 | This Lua module is used on
approximately 266,000 pages. To avoid major disruption and server load, any changes should be tested in the module's /sandbox or /testcases subpages, or in your own module sandbox. The tested changes can be added to this page in a single edit. Consider discussing changes on the talk page before implementing them. |
 | This module is rated as beta, and is ready for widespread use. It is still new and should be used with some caution to ensure the results are as expected. |
Usage
Intended for use in infoboxes; {{#invoke:person height|main|5ft 6in}} → 5 ft 6 in (168 cm). See
Template:Infobox person/height for details.
