letter indicator

[Brendan Goldberg]

I have a "r m/s", where r is a variable and m/s is meters per second.

Which one(s) get the letter indicator?

m/s will be transcribed in Nemeth, according to Rule 4.4.10 since the slash means "per". Rule 10.3 of the Nemeth Code states that the English-letter indicator is used before an abbreviation which consists of one letter. So m and s will each require an ELI.

Whether the variable r needs an ELI depends on the preceding material. Can you provide more context?

The phrase is in the middle of normal text. Basically, "the formula is ..."

Thanks

In order to determine whether a variable needs an English-letter indicator you need to understand the Nemeth definition of "single letter" given in Rule 6.3.1 of the Nemeth code. If your text actually says "the formula is r m/s" then yes the letter r will need an ELI.
