-- Extra conversion data used by Module:Convert.---- defines all units and is transcluded in all pages-- where 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 .
