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

--[[ 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.

These data tables follow:
    SIprefixes          prefixes like 'M' (mega, 10^6)
    units               all properties for a unit, including default output
    default_exceptions  exceptions for default output ('kg' and 'g' have different defaults)
    link_exceptions     exceptions for links ('kg' and 'g' have different links)

SIprefixes is maintained by editing this file.
However, the other tables are generated by a script which reads the wikitext
of a wiki page that documents the required properties of each unit.
The wiki page is currently:

    local result = {}

    end
    return result
end

local function shouldbe(ucode, shouldbe)
    -- Return an error message for a unit that "should be" something else.
    -- Old Template:Convert outputs a much more elaborate message.
