User:Gennaro Prota/SI unit named after a person

From Wikipedia, the free encyclopedia
Jump to: navigation, search


This SI unit has a name derived from the proper name of a person. As such, its symbol begins with a capital letter ({{{symbol}}}). Its name, instead, is always spelled out in lowercase ({{{name}}}), unless it begins a sentence (or is the name "degree Celsius").
— Based on the 7th edition of The International System of Units reference


Usage of the template
  • {{SI unit named after a person | image=André-Marie Ampère.jpg | name=ampere | symbol=a}}
  • {{SI unit named after a person | name=ampere | symbol=a}}
(The parameter image is optional and defaults to the SI Brochure Cover image)
Rationale for the template
These are important SI-related conventions that many get wrong, so it is better making them systematically conspicuous. Using the lowercase template, though not incorrect, would simply point out a different, general, issue.




Some versions which try to incorporate comments provided as of March 11, 2006[edit]

Version 2

Quite explicit, but still not completely exact ("litre" may also be written with an uppercase 'L'):

The {{{name}}} is an SI unit. As such, its symbol ({{{symbol}}}) is internationally fixed, including its letter case, and unaltered in the plural. Its name, instead, may vary across languages and follow local rules or conventions. In English unit names follow the grammar rules for common nouns, except that they are never pluralised.


Version 3

Couldn't be shorter ;)
