-- Extra conversion data used by Module:Convert. -- เดี่ยวเพิ่มภาษาไทย -- -- [[Module:Convert/data]] defines all units and is transcluded in all pages -- where [[Module:Convert]] is used. Testing new units by editing that module -- would invalidate the cache for all affected pages. -- -- For quick changes and experiments with new units, this module can be edited. -- Since this module is transcluded in only a small number of pages, changes -- should cause little server overhead and should propagate quickly. -- -- If a unit is defined in the data module, any definition here is ignored, -- so defining the same unit in both modules is not an error. -- A unit defined here can refer to units that are also defined here, and -- can refer to units defined in the data module. -- -- Periodically, those extra units that are wanted permanently can be removed -- from here after being added to [[Module:Convert/data]].  local extra_units = { }  return { extra_units = extra_units }
