This page defines the conversion data used by Module:Convert. All documentation (from Module:Convert/doc) is at that page.

Do not manually add units to this page. First add the unit definitions in Module:Convert/documentation/conversion data/doc. And then update this page by copying the results from Module:Convert/makeunits (those results appear at Module talk:Convert/makeunits).

Any changes should first be tested at Module:Convert/data/sandbox—see Module:Convert/sandbox/testcases.

New units can be manually added at Module:Convert/extra as a temporary measure before being incorporated into this main table.

-- Conversion data used by [[Module:Convert]] which uses mw.loadData() for
-- read-only access to this module so that it is loaded only once per page.
-- See [[:en:Template:Convert/Transwiki guide]] if copying to another wiki.
--
-- These data tables follow:
--   all_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)
--
-- These tables are generated by a script which reads the wikitext of a page that
-- documents the required properties of each unit; see [[:en:Module:Convert/doc]].
 
---------------------------------------------------------------------------
-- Do not change the data in this table because it is created by running --
-- a script that reads the wikitext from a wiki page (see note above).   --
