Template:SI unit lowercase/doc

Usage

Code

{{SI unit lowercase|Blaise Pascal|pascal|Pa}}

Produces

The pascal is named after Blaise Pascal. As with every SI unit named for a person, its symbol starts with an upper case letter (Pa), but when written in full it follows the rules for capitalisation of a common noun; i.e., "pascal" becomes capitalised at the beginning of a sentence and in titles, but is otherwise in lower case.

Rationale

These are important SI-related rules that many get wrong, so it is better that we make them systematically conspicuous. Using the lowercase title template would be incorrect, since SI units behave like all other common nouns. The SI explicitly states that they can be capitalised at the beginning of sentences and in titles.
