Template:Convert

Template documentation[view] [edit] [history] [purge]

For currency conversion into US dollars, see Template:To USD

Template {{convert}} calculates from one measurement unit to another one, and then presents the results formatted. The complete list of unit symbols recognized by the template is at Module:Convert/documentation/conversion data.

For example:

{{convert|2|km|mi}} → Template:Convert/km

(km entered, so converted into mile)

{{convert|7|mi|km}} → Template:Convert/mi

(mi entered, so converted into km)

Numbers can be rounded, units can be abbreviated into symbols:

{{convert|2|km|mi|2|abbr=on}} → Template:Convert/km

{{convert|7|mi|km|2|abbr=on}} → Template:Convert/mi

Value ranges can be entered using |to|... or |-|...:

{{convert|2|to|5|km|mi}} → Template:Convert/to

{{convert|2|-|5|km|mi}} → Template:Convert/-

Combined effect example:

{{convert|2|-|5|km|mi|2|abbr=on}} → Template:Convert/-

{{convert|2|and|5|km|mi|sigfig=3|abbr=off}} → Template:Convert/and

See Help:Convert for more detailed, technical information

Units to convert

See also: the summary at Complete list of units for {{Convert}} and the complete list at Module:Convert/documentation/conversion data

Enter units to convert from into:

• {{convert|1|lb|kg}} → Template:Convert/lb

SI units generally accept prefixes, like "m" for milli (10⁻³), and "M" for mega (10⁶)

For "per" units, use "/" (slash): kg/ha

For three-unit units, etc., see Category:Convert-like templates

Unit name or symbol (abbreviation): 1 pound or 1 lb?

By default, the first quantity shows the unit name, the second shows the symbol (or abbreviation):

• {{convert|1|lb|kg}} → Template:Convert/lb

Using |abbr=in is the reverse behaviour to the default:

• {{convert|1|lb|kg|abbr=in}} → Template:Convert/lb

To abbreviate both or neither:

• {{convert|1|lb|kg|abbr=on}} → Template:Convert/lb

• {{convert|1|lb|kg|abbr=off}} → Template:Convert/lb

Convenience: {{cvt}} has |abbr=on by default

Template {{cvt}} is the same as {{convert}}, except that it has |abbr=on as the default behaviour. In {{cvt}}, all other options are available. So:

{{cvt|1|lb|kg}} → 1 lb (0.45 kg)

is equivalent to:

{{convert|1|lb|kg|abbr=on}} → 1 lb (0.45 kg)

Adjective: a 10-mile distance

Use |adj=on to produce the adjectival (hyphenated) form:

• A {{convert|10|mi|km|adj=on}} distance → A Template:Convert/mi

distance.

Default behaviour, for comparison:

• {{convert|10|mi|km}} to go → Template:Convert/mi

to go.

|adj=on does not produce hyphens with unit symbols, as per Manual of Style:

• A {{convert|9|in|cm|adj=on|abbr=on}} nail → A Template:Convert/in

nail.

Rounding: 100 ft is 30 m or 30.5 m or 30.48 m?

See Help:Convert § Rounding for a more mathematical description of the rounding options

By definition, 100 ft equals Template:Convert/ft . In practical use, it is common to round the calculated metric number. With that, there are several possibilities.

Default rounding

By {{Convert}} default, the conversion result will be rounded either to precision comparable to that of the input value (the number of digits after the decimal point—or the negative of the number of non-significant zeroes before the point—is increased by one if the conversion is a multiplication by a number between 0.02 and 0.2, remains the same if the factor is between 0.2 and 2, is decreased by 1 if it is between 2 and 20, and so on) or to two significant digits, whichever is more precise. An exception to this is rounding temperatures (see below).

Examples of rounding
Input	Displays as	Note
{{convert|123|ft|m|-1}}	Template:Convert/ft
{{convert|123|ft|m}}	Template:Convert/ft	same output as with 0 (below)
{{convert|123|ft|m|0}}	Template:Convert/ft
{{convert|123|ft|m|1}}	Template:Convert/ft
{{convert|123|ft|m|2}}	Template:Convert/ft	The more-exact value is 37.4904 m or so, which gets converted to 37 m if this parameter is not specified at all.
{{convert|500|ft|m|-1}}	Template:Convert/ft
{{convert|500|ft|m}}	Template:Convert/ft	same output as with −1 (above), because the conversion factor is between 0.2 and 2 (hence, it should produce same double-zero precision (−2) as in the input value), but the conversion must produce two significant digits at a minimum (hence, a higher single-zero precision (−1) is used)
{{convert|500|ft|m|0}}	Template:Convert/ft
{{convert|500|ft|m|1}}	Template:Convert/ft
{{convert|500|ft|m|2}}	Template:Convert/ft	exact value is 152.4 m
{{convert|500|ft|cm|-3}}	Template:Convert/ft
{{convert|500|ft|cm}}	Template:Convert/ft	same output as with −3 (above), because the conversion factor is between 20 and 200 (hence, it should decrease input value's double-zero precision (−2) by 2), but the conversion must produce two significant digits at a minimum (hence, a higher triple-zero precision (−3) is used)
{{convert|500|ft|cm|0}}	Template:Convert/ft

Convert supports four types of rounding:

Round to a given precision: use a precision number

Specify the desired precision with the fourth unnamed parameter (or third unnamed parameter if the "convert to" parameter is omitted; or fifth unnamed parameter if a range is specified; or fourth unnamed parameter again if a range is specified and the "convert to" parameter is omitted; needs to be replaced with a "precision" named parameter). The conversion is rounded off to the nearest multiple of ​¹⁄₁₀ to the power of this number. For instance, if the result is 8621 and the round number is "-2", the result will be 8600. If the result is "234.0283043" and the round number is "0", the result will be 234.

Round to a given number of significant figures: |sigfig=

To specify the output number to be with n significant figures use |sigfig=<number>:

• {{convert|1200|ft|m|sigfig=4}} → Template:Convert/ft

• {{convert|1200|ft|m|sigfig=3}} → Template:Convert/ft

• {{convert|1200|ft|m|sigfig=2}} → Template:Convert/ft

• {{convert|1200|ft|m|sigfig=1}} → Template:Convert/ft

Default behaviour, for comparison:

• {{convert|1200|ft|m}} → Template:Convert/ft

Setting |sigfig= to a value less than 1 is meaningless:

• {{convert|1200|ft|m|sigfig=0}} → Template:Convert/ft

N

Round to a multiple of 5: 15, 20, 25, ...

Using |round=5 rounds the outcome to a multiple of 5.

• {{convert|10|m|ft}} → Template:Convert/m

• {{convert|10|m|ft|round=5}} → Template:Convert/m

Similar: using |round=25 rounds the outcome to a multiple of 25.

• {{convert|10|m|ft}} → Template:Convert/m

• {{convert|10|m|ft|round=25}} → Template:Convert/m

Default behaviour, for comparison:

• {{convert|10|m|ft|sigfig=4}} → Template:Convert/m

In a range, one can round each value individually to the default. Use |round=each:

• {{convert|10 x 200 x 3000|m|ft}} → Template:Convert/m

• {{convert|10 x 200 x 3000|m|ft|round=each}} → Template:Convert/m

Round to a multiple of a given fraction: ​2 ³⁄₁₆ inch

Specify the desired denominator using |frac=<some positive integer>. (Denominator is the below-the-slash number, for example the 3 in ​¹⁄₃).

• {{convert|5.56|cm|in|frac=16}} → Template:Convert/cm

• {{convert|8|cm|in|frac=4}} → Template:Convert/cm

The fraction is reduced when possible:

• {{convert|8|cm|in|frac=100}} → Template:Convert/cm

Default behaviour uses decimal notation:

• {{convert|5.56|cm|in}} → Template:Convert/cm

Rounding temperatures: °C, °F and K

In temperatures, the conversion will be rounded either to the precision comparable to that of the input value or to that which would give three significant figures when expressed in kelvins, whichever is more precise.

1. {{convert|10,000|C|F K}} → Template:Convert/C

1. {{convert|10,000.1|C|F K}} → Template:Convert/C

1. {{convert|-272|C|F K}} → Template:Convert/C

1. {{convert|-272|C}} → Template:Convert/C

1. {{convert|100|C|F K}} → Template:Convert/C

1. {{convert|0|C|F K}} → Template:Convert/C

The precision of the input number in example (1) is one digit, but the precision of its Kelvins expression is three, so the precision of the Fahrenheit conversion is made three (made 180...) . (1) and (2) seem to belie the fact that a Template:Convert/C-change , and make the 32 degrees difference shown in (1) begin to seem off somehow. Result (1) seems off until you set the significant figures yourself with |sigfig=:

{{convert|10000|C|sigfig=5}} → Template:Convert/C

or you set the precision positionally, relative to the decimal point (zero being at the decimal point):

{{convert|10000|C|0}} → Template:Convert/C

The precision of the input number in example (2) is six, so the precision of the Fahrenheit output is, whereas before, Kelvins had determined it to be three. Examples (3) and (4) show how this can be hidden and generate questions, but it occurs there because the Kelvins conversion generated two fractional parts. (Before it was the input number that generated the fractional part.) In example (3) the three input digits converted into five significant output digits because of the two digits after the decimal point, generated by the Kelvins conversion. This happened again in (5), but in (6) decimal fractions were neither given as input nor induced by the Kelvins conversion.

Rounding input

There is limited support for rounding the displayed input number. The rounding takes place after conversion, so the output is based on the full-precision input. This is useful when the input is produced by {{#expr:}} or otherwise available to a higher precision than is usefully displayed, and it's desirable to avoid double-rounding.

To round the input to a specified number of digits after the decimal point, use one of the parameters:

• |adj=ri0
• |adj=ri1
• |adj=ri2
• |adj=ri3

Note that there is no |adj=ri-1N or similar for rounding above the decimal place. Neither is there support for significant figures, multiples of 5, or any other output-rounding feature.

The default precision is computed based on the input, so an explicit output precision must usually be supplied:

• {{convert|4.14159|mi|km|adj=ri0}} → Template:Convert/mi

N (precisions are mismatched)

• {{convert|4.14159|mi|km|0|adj=ri0}} → Template:Convert/mi

Y

In this case, if the input were rounded before conversion, a different result would be obtained:

• {{convert|{{#expr:4.14159 round 0}}|mi|km|0}} → Template:Convert/mi

N (double rounding)

==Into multiple units: Template:Convert/C == Separate the multiple output units by a space:

• {{convert|10|C|F K}} → Template:Convert/C

• {{convert|5|km|mi nmi}} → Template:Convert/km

If the output unit names contain spaces, use + as the separator.

See also:

• For multiple-unit options like 1 ft 5 in, see § In input and § In output.

Ranges of values

For a conversion of a difference, see § Units of difference.

A range converts two values and separates them by your choice of words and punctuation.

A range: 6 to 17 kg (13 to 37 lb)

Range indicators are entered as the second parameter (between the values). Range separators can be:

Range separators in {{convert}}
Separator	Convert	Result	Notes
-	{{convert|3|-|6|ft}}	Template:Convert/-	Input can be hyphen (-) or en dash (–), output uses en dash
– – (en dash)	{{convert|3|–|6|ft}}	Template:Convert/–
and	{{convert|3|and|6|ft}}	Template:Convert/and
and(-)	{{convert|3|and(-)|6|ft}}	Template:Convert/and(-)	|abbr=on abbreviates the first unit
and(-)|abbr=on	{{convert|3|and(-)|6|ft|abbr=on}}	Template:Convert/and(-)

,	{{convert|3|,|6|ft}}	Template:Convert/,
, and	{{convert|3|, and|6|ft}}	Template:Convert/, and
, or	{{convert|3|, or|6|ft}}	Template:Convert/, or
by	{{convert|3|by|6|ft}}	Template:Convert/by
x	{{convert|3|x|6|ft}}	Template:Convert/x	|abbr=on abbreviates and repeats the first unit
× ×	{{convert|3|×|6|ft}}	Template:Convert/×
x|abbr=on	{{convert|3|x|6|ft|abbr=on}}	Template:Convert/x
xx	|xx| is deprecated. Use |x| instead
*	|*| is deprecated. Use |x| instead

===Multiple dimensions: Template:Convert/x === Use by:

• {{convert|6|by|12|ft|m}} → Template:Convert/by

Use ×, multiplication sign, or x, letter:

• {{convert|6|x|12|m|ft}} → Template:Convert/x

In science, the formal way is to set |x| and |abbr=on (keeping dimensions right, like in area = x km²):

• {{convert|6|x|12|m|ft|abbr=on}} → Template:Convert/x

Lists of values: 20, 40, or 60 miles

{{convert|20|,|40|, or|60|mi}} → Template:Convert/,

About feet, inch in ranges and multiples

While it is possible to enter feet, inch in a simple conversion, this is not possible for ranges:

• {{convert|1|ft|3|in|x|3|ft|5|in|mm}} → Template:Convert/ft

N

Default behaviour, for comparison:

• {{convert|1|ft|3|in|mm}} → Template:Convert/ft

However, converting metric units into feet and inches with |order=flip can produce the desired output:

• {{convert|380|x|1040|mm|ftin|order=flip}} → Template:Convert/x

Words

Spelling of unit name: international metre or US meter?

Default spelling of units is in the en (generic) locale. To show en-US spelling, use |sp=us:

{{convert|1|m|ft}} → Template:Convert/m

—default

{{convert|1|m|ft|sp=us}} → Template:Convert/m

Spell out numbers: ten miles

To write a number in words, use |spell=in:

• {{convert|10|mi|m|spell=in}} → Template:Convert/mi

To spell out both in and out values, use |spell=on:

• {{convert|10|mi|m|spell=on}} → Template:Convert/mi

To make first letter a capital, use |spell=In, |spell=On

• {{convert|10|mi|m|spell=In}} → Template:Convert/mi

• {{convert|10|mi|m|spell=On}} → Template:Convert/mi

Remember that the spelling of the units (ft, m) is independently set by |abbr=. To the extreme:

• {{convert|10|mi|m|spell=on|abbr=off|sp=us}} → Template:Convert/mi

Inserted before units: 4 planted acres

• {{convert|4|acre||adj=pre|planted}} → Template:Convert/acre

disp=preunit is similar, but has no separator after the specified text, and can have different text for the output value:

• {{convert|4|acre||disp=preunit|planted }} → Template:Convert/acre

• {{convert|4|acre||disp=preunit|planted |reforested-}} → Template:Convert/acre

===After adjective unit: A Template:Convert/ft

corridor===

Note that two units (in this case, ft and m) are required. Use with just one unit will generate an error message.

{{convert|10|ft|m|adj=mid|-long}} → Template:Convert/ft

Plurals: 1 inch, 2 inches

The unit symbol is singular always. Depending on the preceding number only, a unit name can be shown plural.

• {{convert|1|metre}} → Template:Convert/metre

• {{convert|2|metre}} → Template:Convert/metre

• {{convert|2|metre|abbr=on}} → Template:Convert/metre

Exception

Entering the unit spelled |foot| forces singular output "foot", whatever the number is.

• {{convert|100|foot|abbr=off}} → Template:Convert/foot

Fractions: one-eighth of an imperial pint

The convert template also supports spelling out fractions.

• {{convert|3+1/2|oz|g|spell=in}} → Template:Convert/oz

Any additional words needed for the fraction can also be added at the end of the template.

• {{convert|1/8|imppt|ml|spell=in|adj=pre|of an}} → Template:Convert/imppt

Wrapping and line breaking

See Help:Convert § Wrapping and line breaking

Spelling out "thousands", "millions", etc.

Most unit codes accept a prefix of e3 (thousand) or e6 (million) or e9 (billion).

• {{convert|100|e6mi|e6km}} → Template:Convert/e6mi

• {{convert|120|e6acre}} → Template:Convert/e6acre

• {{convert|120|e6acre|e3km2}} → Template:Convert/e6acre

To display both input and output in scientific notation, use |abbr=on

• {{convert|100|e6mi|e6km|abbr=on}} → Template:Convert/e6mi

To spell out "thousands", "millions", etc., |abbr=unit abbreviates the unit; |abbr=off displays both full unit names.

• {{convert|100|e6mi|e6km|abbr=unit}} → Template:Convert/e6mi

• {{convert|100|e6mi|e6km|abbr=off}} → Template:Convert/e6mi

Numbers

Using an SI prefix: gigametre (Gm), or micrometre (μm)

Template:Sidebar metric prefixes (small) Units can have an SI prefix like G before the unit: Gm, and giga before the name: gigametre. These are plain multiplication factors.

To illustrate, these are trivial calculations (from metre to metre), showing the multiplication factor:

• Template:Convert/Gm

• Template:Convert/μm

The prefix can be added before the SI unit (here: unit m for metre):

• {{convert|12|Gm|mi|abbr=on}} → Template:Convert/Gm

• Mm: Template:Convert/Mm

• km: Template:Convert/km

• mm: Template:Convert/mm

• μm: Template:Convert/μm

• um: Template:Convert/um

(letter "u" can be used for "μ" here)

The prefix can be used in the output unit:

• {{convert|12000|mi|Mm|abbr=on}} → Template:Convert/mi

• {{convert|12|in|μm|abbr=on}} → Template:Convert/in

As an exception, the non-SI unit "inch" can have the "μ" prefix too:

• {{convert|12|μm|μin|abbr=on}} → Template:Convert/μm

Further information: Help:Convert units § SI prefixes

Engineering notation: 7 × 10⁶ m

In the unit: e6m

Engineering notation can be entered as a "prefix" to the unit:

• {{convert|70|e6m}} → Template:Convert/e6m

The same is possible for the output unit:

• {{convert|23,000,000|ft|e6m}} → Template:Convert/ft

Any standard unit (not a combination, multiple, or built-in unit) can have such a prefix:

• e3 (thousand),
• e6 (million),
• e9 (billion),
• e12 (trillion),
• e15 (quadrillion).

Scientific notation: 1.23 × 10⁻¹⁴

In scientific notation, a number is written like 1.23×10⁻¹⁴. The plain number has exactly one digit before the decimal point.

With {{convert}}, the input can be in e-notation such as 12.3e4. This value is displayed as a power of ten, and the output is displayed in scientific notation, except that an output value satisfying 0.01 <= v < 1000 is shown as a normal number. In addition, if the output value is 1000 and sigfig=4 is used, the value is displayed as a normal number.

• {{convert|12.3e-15|atm|atm|abbr=on}} → Template:Convert/atm

• {{convert|0.00000005|atm|atm|abbr=on}} → Template:Convert/atm

===Input with fractions: Template:Convert/in === The number to convert can be written in fractions. Both / (keyboard slash) and ⁄ (fraction slash) are accepted:

• {{convert|1/2|in|mm|1}} → Template:Convert/in

• {{convert|1⁄2|in|mm|1}} → Template:Convert/in

With positive mixed numbers (a positive integer and a fraction), use a + sign

• {{convert|2+1⁄2|in|mm|1}} → Template:Convert/in

With negative mixed numbers, use a hyphen - and repeat it:

• {{convert|-2-1⁄2|in|mm|1}} → Template:Convert/in

Note that the following cases are not interpreted as mixed numbers:

• {{convert|2-1⁄2|in|mm|1}} → Template:Convert/in

. This is interpreted as a range from 2 inches to 1⁄2 inch.

• {{convert|-2+1⁄2|in|mm|1}} → Template:Convert/in

N This is neither a mixed number nor a range, and mathematical expressions requiring calculations are not allowed here.

Horizontal fraction bar: 1/2 inch

Using a double slash (//) provides a horizontal fraction bar for the original (input) unit:

• {{convert|1//2|in|mm|1}} → Template:Convert/in

• {{convert|6+3//8|in|mm|1}} → Template:Convert/in

Using a negative value for |frac= provides a horizontal fraction bar for the converted (output) unit:

• {{convert|12.7|mm|frac=-2}} → Template:Convert/mm

• {{convert|161.9|mm|frac=-8}} → Template:Convert/mm

Thousands separator: 1,000 mi or 1000 mi

In input, a comma for thousands separator is accepted but not required; a gap (space) is not accepted. In output, by default, the thousand separator is the comma:

• {{convert|1234567|m|ft}} → Template:Convert/m

• {{convert|1,234,567|m|ft}} → Template:Convert/m

Set |comma=off to remove the separator from the output:

• {{convert|1234567|m|ft|comma=off}} → Template:Convert/m

Use |comma=gaps to use digit grouping by gap (thin space) as a thousands separator:

• {{convert|1234567|m|ft|comma=gaps}} → Template:Convert/m

Default behaviour, for comparison:

• {{convert|1234567|m|ft}} → Template:Convert/m

Setting |comma=5 will only add the separator when the number of digits is 5 or more:

• {{convert|1234|m|ft|comma=5}} → Template:Convert/m

• {{convert|1234567|m|ft|comma=5}} → Template:Convert/m

Default behaviour, for comparison:

• {{convert|1234|m|ft}} → Template:Convert/m

Output manipulation

Brackets and separators: 10 m [33 ft]

Punctuation that distinguishes the two measurements is set by |disp=.
Options are: b (the default), sqbr, comma, or, br, br(), x|…:

• {{convert|10|m|ft|disp=sqbr}} → Template:Convert/m

• {{convert|10|m|ft|disp=comma}} → Template:Convert/m

• {{convert|10|m|ft|disp=or}} → Template:Convert/m

Default behaviour, for comparison:

• {{convert|10|m|ft}} → Template:Convert/m

Setting |disp=br will force a new line (<br/>)

• {{convert|10|m|ft|disp=br}} → Template:Convert/m

Also |disp=br() will force a new line, and keep the brackets (useful in tables):

• {{convert|10|m|ft|disp=br()}} → Template:Convert/m

Setting |disp=x|… allows any text as separator:

• {{convert|10|m|ft|disp=x|_MyText_}} → Template:Convert/m

(To display spaces, use  )

===Flipping (reordering) the two measurements: Template:Convert/mi === Setting |order=flip will flip (swap) the two measurements:

• {{convert|1|mi|m|order=flip}} → Template:Convert/mi

Default behaviour, for comparison:

• {{convert|1|mi|m}} → Template:Convert/mi

When converting to multiple units, the effect is:

• {{convert|10|km|mi nmi|order=flip}} → Template:Convert/km

• {{convert|10|km|nmi mi|order=flip}} → Template:Convert/km

===Fixed ordering of output units: Template:Convert/C === Setting |order=out shows the output-units as ordered; the input unit is skipped:

• {{convert|100|C|F C K|abbr=on|order=out}} → Template:Convert/C

• {{convert|200|PS|kW hp|0|abbr=on|order=out}} → Template:Convert/PS

See also: § Displaying parts of the output.

=== Displaying parts of the result: Template:Convert/cuyd === It is possible to display only parts of the conversion result:

Convert	Output	Returns
{{convert|2|cuyd|m3}}	Template:Convert/cuyd	Regular output (for comparison)
{{convert|2|cuyd|m3|abbr=values}}	Template:Convert/cuyd	Input and output numbers
{{convert|2|cuyd|m3|disp=unit}}	Template:Convert/cuyd	Input unit
{{convert|2|cuyd|m3|disp=unit|adj=on}}	Template:Convert/cuyd	Input unit, adjective (hyphenated)
{{convert|2|cuyd|cuyd|disp=out}}	Template:Convert/cuyd	Input (workaround. Note repetition of unit in input)
{{convert|2|cuyd|m3|abbr=~}}	Template:Convert/cuyd	Input: both name and symbol
{{convert|2|cuyd|m3|disp=unit2}}	Template:Convert/cuyd	Output unit (symbol)
{{convert|2|cuyd|m3|disp=unit2|abbr=off}}	Template:Convert/cuyd	Output unit (name)

{{convert|2|cuyd|m3|disp=out|abbr=off}}	Template:Convert/cuyd	Output value and unit symbol

Display both input name and symbol: 2 kilopascals [kPa]

Setting |abbr=~ returns both name and symbol of the first (input) unit:

• {{convert|2|kPa|psi|abbr=~}} → Template:Convert/kPa

• A {{convert|2|kPa|psi|abbr=~|adj=on}} pressure → A Template:Convert/kPa

pressure

Table options

For the wikitable structure, there are three options: add a line-break, split the result over columns and make the table sortable.

Enforced line break

|disp=br adds a line-break and omits brackets.

|disp=br() adds a line-break and does add brackets to the converted value. This may be useful in tables:

|disp=br	|disp=br()
Template:Convert/km	Template:Convert/km

Table columns

Using {convert} in a table cell, with |disp=table splits the result over two (or more) columns. By default units are not included in the table, however, they can be added using the |abbr= parameter. Multiple-unit outputs, like ftin, always output their units to the table.

{{convert|10|m|ft|disp=table}} →

Template:Convert/m

|disp=tablecen does the same, and also centers the text:

{{convert|20|m|ft|disp=tablecen}} →

Template:Convert/m

The units are added as a column header:

	kilograms	pounds	stone and pounds
|disp=table	Template:Convert/kg
|disp=table and |abbr=on	Template:Convert/kg
|disp=table and |abbr=off	Template:Convert/kg
|disp=tablecen	Template:Convert/kg
|disp=<other> (default)	Template:Convert/kg

Sorting

Use |sortable=on to include a hidden numerical sortkey in the output, suitable for use in a table with sortable columns. Technically, this places a hidden string before the actual displayed values:

{{convert|10|m|ft|sortable=on}} → <span data-sort-value="7001100000000000000♠"></span>10 metres (33 ft)

showing: Template:Convert/m

.

Use both |disp=table and |sortable=on together to produce table columns (pipe symbols) for each value in sortable columns:

	m	m	ft
A	15.75 m	Template:Convert/m
B	15.5 m	Template:Convert/m
C	16 m	Template:Convert/m
D	16 m	Template:Convert/m

The generated sortkey is calculated in a consistent way based on both the value and its unit as passed to the convert template. In most cases convert uses the passed value converted to SI base units. It is therefore not necessarily the displayed value or other alternate units and is calculated regardless of output format options. Using different units or different order of units in individual rows should therefore not lead to incorrect sorting, although variations in rounding can give surprising results, since an unrounded number is used for the sortkey.

Units

The conversion factors and physical constants are sourced here.

All units

Units are case-sensitive: use kW, not KW or kw

The table below lists units supported by {{convert}}. More complete lists are linked for each dimension. For a complete list of all dimensions, see full list of units.

{{Convert}} uses unit-codes, which are similar to, but not necessarily exactly the same as, the usual written abbreviation for a given unit. These unit-codes are displayed in column 3 of the following tables. These are accepted as input by {{convert}} as the second and third unnamed parameters:

• {{convert|100|kg|lb}} → Template:Convert/kg

• {{convert|100|lb|kg}} → Template:Convert/lb

The unit-codes should be treated as case-sensitive:

• {{convert|100|Mm|mm}} → Template:Convert/Mm

The output of {{convert}} can display multiple converted units, if further unit-codes are specified after the second unnamed parameter (without the pipe separator). Typical combination output units are listed below in column 7.

• {{convert|55|nmi|km mi}} → Template:Convert/nmi

• {{convert|1|oz|ozt g gr}} → Template:Convert/oz

Some units have alternative unit-codes. These are shown in brackets in column 3, e.g. °F (F). Either may be entered for Fahrenheit (but not a lower-case f).

'per' units: kg/hl, miles per gallon

When using a slash (/), a unit like kg/hl is recognized as kilograms per hectolitre and will be converted with other mass/volume units.

• {{convert|1000|kg/hl}} → Template:Convert/kg/hl

Population density (inhabitants per square mile) can be converted using

• {{convert|10|PD/sqmi|PD/km2}} → Template:Convert/PD/sqmi

Vehicular fuel efficiency, commonly expressed in miles per gallon or litres per 100 km can also be converted

• {{convert|26|mpgUS|l/100km mpgimp}} → Template:Convert/mpgUS

Units of difference: Expressing a change or difference in temperature

We have already discussed standard temperature conversions (°C, °F, K), as shown in these two examples:

• {{convert|10|C}} → Template:Convert/C

(standard temperature conversion)

• {{convert|10–15|C}} → Template:Convert/C

(standard temperature range conversion)

When expressing a temperature change (e.g., "The temperature increased by 10 °C"), or when comparing temperatures (e.g., "10 to 15 °C warmer"), we cannot use the standard temperature units (|C, |F and |K), which refer to points on the respective scale. Instead, we must use one of the following "units of difference": |C-change, |F-change and |K-change.

Compare the following two examples with the two above:

• {{convert|10|C-change}} → Template:Convert/C-change

increase in temperature

• {{convert|10–15|C-change}} → Template:Convert/C-change

warmer than normal

To produce multiple units in the output:

• {{convert|10|C-change|F-change K-change}} → Template:Convert/C-change

difference

Multiple units: 1 ft 5 in

In input

Base document § Input multiples lists options for multiple unit input (like ft,in). It can catch predefined sets only (units that can be subdivided; e.g., yd into ft):

• {{convert|1|yd|2|ft|3|in}} → Template:Convert/yd

• {{convert|2|ft|3|in|cm}} → Template:Convert/ft

• {{convert|1|lb|5|oz|g}} → Template:Convert/lb

In output

Available multiple-unit output options predefined, like ftin and ydftin. The full list is at § Output multiples.

• {{convert|2|m|ftin}} → Template:Convert/m

• {{convert|2|m|ft in}} → Template:Convert/m

, using a space, returns the decimal point Default behaviour, for comparison:

• {{convert|2|m}} → Template:Convert/m

• {{hands}} a length used to measure horses
• {{Long ton}} a weight in ton, cwt, qr and lb

Currency per unit: $/mi → $/km

Using currency symbols in a $ per unit value, you can convert the per-unit:

• {{convert|10|$/mi|$/km}} → Template:Convert/$/mi

• {{convert|1500|$/ozt|$/g}} → Template:Convert/$/ozt

You can set the currency in both values using |$=€:

• {{convert|10|$/mi|$/km|$=€}} → Template:Convert/$/mi

It is not possible to convert the currency. So, this result (mixed currencies) is not possible: $15 per mile (€8.6/km) N

Using convert inside templates

For usage in template code, like infoboxes, {{Convert}} has these options:

Pre-formatting fraction input

• Module:Convert/helper can read regular input and pre-format it into {{Convert}}-accepted input.

Your template can accept |input=16 7/8 and use {{#invoke:Convert/helper|number|16 7/8}} →

Using a Wikidata property

• Adding the Wikidata property code, like code |input=P2073, to your template code automatically returns the Wikidata property for that article, and convert it. Both number and unit are read.

Note: to return that property value for an other article, use |qid=.

Example for (P2073): Note: this example uses |qid=Q1056131 (testing for (Q1056131))

• {{convert|input=P2073|qid=Q1056131|ftin|abbr=on}} → {{convert/{{{2}}}|ftin|0

|||||r=re |d=LoffAonDbSoff|s=}}

• {{convert|input=P2073|qid=Q1056131|km|abbr=on}} → {{convert/{{{2}}}|km|0

|||||r=re |d=LoffAonDbSoff|s=}}

• {{convert|input=P2073|qid=Q1056131|km|abbr=on|disp=out}} → {{convert/{{{2}}}|km|0

|||||r=re |d=LoffAonDoutSoff|s=}}

For example see template:Infobox Telescope.

Sometimes a property may have more than one value against it in Wikidata. You can use the |qual= parameter to specify which of the values you want to use.

Example for (P2386): Note: this example uses |qid=Q1513315 (testing for (Q1513315))

• (Q613628): {{convert|input=P2386|qual=Q613628|ft|abbr=on}} → {{convert/{{{2}}}|ft|0

|||||r=re |d=LoffAonDbSoff|s=}}

• (Q1395645): {{convert|input=P2386|qual=Q1395645|ft|abbr=on}} → {{convert/{{{2}}}|ft|0

|||||r=re |d=LoffAonDbSoff|s=}}

Link units	lk	Indication of what units to apply wikilinks to. Use “on” for all, “in” for the input unit, “out” for the output units, or “off” for none of the units. Default off Example on	String	optional
Abbreviation	abbr	Display for the units: “on” to display all units using their unit symbols, “off” to display all units in full words, “in” to display the unit symbol for the input unit, “out” to display the unit symbols for the output units, “unit” to display unit symbols for both input and output units when using scientific notation, “values” for no units at all (neither unit symbols nor full words of units). Default out Example on, unit, in, out, off	String	suggested
Spelling	sp	Spelling of units. Use “us” to display unit names using U.S. spelling. Example us	String	optional
Adjective	adj	Whether to use adjectival form. Use “on” for singular unit name appended by a hyphen, “mid” to put conversion at end, or “off” (default) for no adjectival form. Default off Example on	Unbalanced wikitext	optional
Conversion	disp	Display conversion result: “or”: after ‘or’, “x”: with custom prefix and suffix, “b”: in parentheses, “table”/“tablecen”, “output only”: alone, “output number only”: alone and without unit, “unit”: not at all but input unit; if the value is a number it is used as precision.
