模块:Convert/doc

This module converts a value from one unit of measurement to another. For example:

• {{convert|123|lb|kg}} → 123 pounds (56 kg)

The module is called using a template—parameters passed to the template are used by this module to control how a conversion is performed. For example, units can be abbreviated (like kg), or displayed as names (like kilogram), and the output value can be rounded to a specified precision. For usage information, see Help:Convert.

Templates and modules

Templates that invoke this module are:

• Template:Convert
• Template:Cvt (convert with abbr=on)

The following modules are required:

• Module:Convert – (this module) code to convert units
• Module:Convert/data – unit definitions
• Module:Convert/text – text messages, and parameter names and values

The following modules are optional and are used only if required and if the module exists:

• Module:Convert/extra – extra (temporary) unit definitions; used if a unit is not found in Module:Convert/data
• Module:ConvertNumeric – code to spell an input value in words (only English is supported; however, see vi:Module:ConvertNumeric)

For Wikidata support the following modules are required:

• Module:Convert/wikidata

The following help pages are available:

• Help:Convert – overview

A page containing a convert error is added to the following hidden category, providing the page is in a specified namespace (articles, by default):

• Category:未获Convert模块承认的单位或选项（0）

Units are defined in the wikitext of the master list of units.

• Module:Convert/makeunits – translates wikitext from the master list to Lua
• Module talk:Convert/makeunits – makeunits results; copy the text to Module:Convert/data

Module:Convert/data is transcluded into every page using the convert module, so experimenting with a new unit in that module would involve a significant overhead. The Module:Convert/extra module is an alternative which is only transcluded on pages with a unit that is not defined in the main data module.
