The purpose of this module is to prepare the data used by Module:Convert to allow conversion between units of measurement.
Usage: Put one of the following lines (with nothing else) in a sandbox:
{{#invoke:convert/makeunits|makeunits}}{{subst:#invoke:convert/makeunits|makeunits}}
Previewing the sandbox should display the wikitext that needs to be copied and pasted into Module:Convert/data. If a problem occurs, warning messages will be displayed to indicate that the unit definitions need to be fixed.
A bug somewhere means that currently the first method shown above fails (see report). However, the second works.
By default, the module reads the unit definitions from Module:Convert/documentation/conversion data/doc. For testing purposes, it is possible to specify that the definitions are read from another page, for example, User:Johnuniq/sandbox2, by specifying the wanted title:
{{#invoke:convert/makeunits|makeunits|User:Johnuniq/sandbox2}}{{subst:#invoke:convert/makeunits|makeunits|User:Johnuniq/sandbox2}}
The module reads localization information from Module:Convert/text.
The module contains table specials which is used to insert a small amount of "built-in" data that is not currently defined in the input wikitext.
