Wikipedia Manual of Style Units of Measurement. The main unit in which a quantity is expressed should generally be an SI <https://nam01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fen.wikipedia.org%2Fwiki%2FInternational_System_of_Units&data=02%7C01%7Cusma%40lists.colostate.edu%7C7efefa4551744e46f44c08d7d85ae59a%7Cafb58802ff7a4bb1ab21367ff2ecfc8b%7C0%7C0%7C637215757224986986&sdata=cwsZ5%2BZvtytV5OYChjt5EOMiEr1pt8%2BPle5nMOhMFPE%3D&reserved=0> unit or non-SI unit officially accepted for use with the SI <https://nam01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fen.wikipedia.org%2Fwiki%2FNon-SI_units_mentioned_in_the_SI&data=02%7C01%7Cusma%40lists.colostate.edu%7C7efefa4551744e46f44c08d7d85ae59a%7Cafb58802ff7a4bb1ab21367ff2ecfc8b%7C0%7C0%7C637215757224986986&sdata=kanri8zDKjvVK35OsclWojxFy%2BrAWABvJ0tfqF4%2BnfY%3D&reserved=0>. However, Scientific articles may also use specialist units appropriate for the branch of science in question. In non-scientific articles with strong ties to the United States, the main unit is generally a U.S. customary unit (22 pounds (10 kg)). In non-scientific articles with strong ties to the United Kingdom, although the main unit is generally a metric unit (10 kilograms (22 lb)), imperial units are still used as the main units in some contexts (7 miles (11 km) by road). Where English-speaking countries use different units for the same measurement, provide a conversion in parentheses. Examples: the Mississippi River is 2,320 miles (3,734 km) long; the Murray River is 2,375 kilometres (1,476 mi) long. The {{convert <https://nam01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fen.wikipedia.org%2Fwiki%2FTemplate%3AConvert&data=02%7C01%7Cusma%40lists.colostate.edu%7C7efefa4551744e46f44c08d7d85ae59a%7Cafb58802ff7a4bb1ab21367ff2ecfc8b%7C0%7C0%7C637215757224986986&sdata=lEgxoKvmg1JlDOFYfjTdLE9jS0NP0gh4m18L2Wic1yI%3D&reserved=0>}} template is useful for producing such expressions. In a direct quotation, always retain the source's units. Any conversion should follow in square brackets (or, an obscure use of units can be explained in a footnote <https://nam01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fen.wikipedia.org%2Fwiki%2FWikipedia%3AFootnotes&data=02%7C01%7Cusma%40lists.colostate.edu%7C7efefa4551744e46f44c08d7d85ae59a%7Cafb58802ff7a4bb1ab21367ff2ecfc8b%7C0%7C0%7C637215757224986986&sdata=8DEybr3Hh60P9yqPFsREIoN2OCm4GYHm7COMpBq6roU%3D&reserved=0>). Where space is limited (such as tables, infoboxes, parenthetical notes, and mathematical formulas) unit symbols are preferred. In prose, unit names should be given in full if used only a few times but symbols may be used when a unit (especially one with a long name) is used repeatedly after spelling out the first use (e.g. Up to 15 kilograms of filler is used for a batch of 250 kg), except for unit names that are hardly ever spelled out (°C rather than degrees Celsius). Most unit names are not capitalized. (For spelling differences, follow § National varieties of English <https://nam01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fen.wikipedia.org%2Fwiki%2FWikipedia%3AManual_of_Style%23National_varieties_of_English&data=02%7C01%7Cusma%40lists.colostate.edu%7C7efefa4551744e46f44c08d7d85ae59a%7Cafb58802ff7a4bb1ab21367ff2ecfc8b%7C0%7C0%7C637215757224986986&sdata=vnnLk%2F3euPXYVkRXdZoC%2BhMjG73FL1T%2Ba5aAB9eoKIw%3D&reserved=0>.) Use "per" when writing out a unit, rather than a slash: metre per second, not metre/second. Units unfamiliar to general readers should be presented as a name–symbol pair on first use, linking the unit name (Energies were originally 2.3 megaelectronvolts <https://nam01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fen.wikipedia.org%2Fwiki%2FMegaelectronvolt&data=02%7C01%7Cusma%40lists.colostate.edu%7C7efefa4551744e46f44c08d7d85ae59a%7Cafb58802ff7a4bb1ab21367ff2ecfc8b%7C0%7C0%7C637215757224986986&sdata=6tPV10kt%2FXFRGH9Tz9VTypQ%2BtYH0EZZhRIZ9cLuZ%2F%2B8%3D&reserved=0> (MeV), but were eventually 6 MeV).
The above does not seem to deter some people from choosing non metric units and insisting that it is the norm, as in Canada. It’s difficult keeping everyone happy !
