Module:Convert/data

Documentation for this module may be created at Module:Convert/data/doc

--[[
This module contains most conversion data used by Module:Convert.
This is a separate file on the assumption that the bytecode will be cached,
and having Module:Convert "require" this should not be slow.

Three data tables follow:
    SIprefixes      prefixes like 'M' (mega, 10^6)
    units           all properties for a unit, including default output
    defaultunits    default output exceptions ('Mg' and 'g' have different defaults)

SIprefixes and defaultunits are maintained by editing this file.
However, the units table is generated by a script which reads the wikitext
for a wiki page that documents properties of units.
The wiki page is currently:
http://en.wikipedia.org/wiki/User:Johnuniq/Conversion_data

Check values at:
