It says it is a symbol for litre (unit). AIUI, this is just a script version of the letter l. All Wikipedia says is that it is "sometimes used in mathematics and elsewhere" (e.g. ℓ-adic representations). Equinox ◑ 00:00, 10 June 2012 (UTC)

- It is a script version of l, but it's used, just like l is. It's tedious to search for, but one book suggests it's most common in the US, Japan and Greece. - -sche (discuss) 20:43, 11 June 2012 (UTC)
- RFV-failed for now, sense (re)moved: the entry now says "script version of l", and "l" is an abbreviation for liter, so the information is still there, people just have to click through to [[l]]. - -sche (discuss) 05:10, 12 October 2012 (UTC)
