Mô đun:Convert/extra
Tài liệu mô đunThis module can be used to quickly add a new unit for use with {{convert}}. When satisfied that a unit is working correctly, ask at Thảo luận Mô đun:Convert for the unit to be moved to the permanent list of units.
The following extracts from Mô đun:Convert/data show examples that could be used to define a new unit. Any number of spaces can be used where blanks are shown in the following.

|---|---|
symbol | Unit identifier used when abbr=on is in effect. |
name1 | Singular name of the unit used when abbr=off is in effect. |
name2 | Plural name of the unit; not required if it is the same as name1 plus "s". |
name1_us | Singular name when sp=us is in effect; not required if the same as name1. |
name2_us | Plural name when sp=us is in effect; not required if the same as name1_us plus "s". |
utype | Unit type; must be exactly the same as the utype of any other unit used in a conversion. |
scale | Number of base units in the unit being defined. |
default | Unit code of the default output used when no output unit is specified in a conversion. |
target | Unit code of an existing unit (the unit being defined "redirects" to the existing unit). |
prefixes | Use 1 if an SI prefix is accepted; 2 is used for m2, and 3 is used for m3. |
link | Article title used when lk=on is in effect; not required if it is the same as name1. |
-- Extra conversion data used by Mô đun:Convert.---- [[Mô đun:Convert/data]] defines all units and is transcluded in all pages-- where [[Mô đun: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 [[Mô đun:Convert/data]].local extra_units = { ["Mile"] = { symbol = "dặm", usename = 1, utype = "length", scale = 1609.344, default = "km", }, -- [[Hệ đo lường cổ Việt Nam]] ["chai vai"] = { name1 = "chai vai", symbol = "chai vai", utype = "length", scale = 14.63, default = "m", link = "Hệ đo lường cổ Việt Nam", }, ["công"] = { name1 = "công", symbol = "công", utype = "area", scale = 1000, default = "m2", link = "Hệ đo lường cổ Việt Nam", }, ["túc"] = { name1 = "túc", symbol = "túc", utype = "volume", scale = (3+1/3)*10^-9, default = "µL", link = "Hệ đo lường cổ Việt Nam", }, ["uyên"] = { name1 = "uyên", symbol = "uyên", utype = "volume", scale = 0.001, default = "L", link = "Hệ đo lường cổ Việt Nam", }, ["tau"] = { name1 = "tau", symbol = "tau", utype = "volume", scale = 0.001*20, default = "L", link = "Hệ đo lường cổ Việt Nam", }, ["cây"] = { name1 = "cây", symbol = "cây", utype = "mass", scale = 0.001*37.50, default = "g", link = "Hệ đo lường cổ Việt Nam", }, ["chỉ"] = { name1 = "chỉ", symbol = "chỉ", utype = "mass", scale = 0.001*3.75, default = "g", link = "Hệ đo lường cổ Việt Nam", }, ["canh"] = { name1 = "canh", symbol = "canh", utype = "time", scale = 3600*2, default = "h", link = "Hệ đo lường cổ Việt Nam", },}return { extra_units = extra_units }
