 | This Lua module is used on 1,000,000+ pages. To avoid large-scale disruption and unnecessary server load, any changes to it should first be tested in the module's /sandbox or /testcases subpages. The tested changes can then be added to this page in a single edit. Please consider discussing changes on the talk page before implementing them. |

 | This module is subject to page protection. It is a highly visible module in use by a very large number of pages, or is substituted very frequently. Because vandalism or mistakes would affect many pages, and even trivial editing might cause substantial load on the servers, it is protected from editing. |
Note: The code which this module's main function (coord) outputs is directly parsed and/or manipulated by Module:Location map and other functions of this module itself (coord2text and coordinsert). If the structure of the output changes (for example, to use the <mapframe> and <maplink> tags), please update the aforementioned scripts as well.
Using the module with coordinsert
When using the {{Coord}} template inside another template, like an infobox, there may be parameters (like type:airport) which should be added automatically. To do so, do something like this:
{{#if:{{{coordinates|}}}|{{#invoke:Coordinates|coordinsert|{{{coordinates|}}}|parameter1:value1|parameter2:value2|parameter3:value3…}}|
Do not add more vertical bars | than necessary.
Using the module with coord2text to extract latitude or longitude
Developers maintaining legacy code may need to extract latitude or longitude to use a parameters in other code, or a mathematical expression. The module's "coord2text" function can be used to extract data from the {{Coord}} template. To extract the latitude from a Coord template, use:
{{#invoke:coordinates|coord2text|{{Coord|57|18|22|N|4|27|32|E}}|lat}} →
To extract the longitude, use:
{{#invoke:coordinates|coord2text|{{Coord|57|18|22|N|4|27|32|E}}|long}} → Lua error in mw.text.lua at line 219: bad argument #1 to 'len' (string expected, got nil).
