I've seen them both, but the official form is `L': `Unit symbols are expressed in lowre-cas letters excep the symbol for "litre", the symbols for untis named after people and the symbols for units containing one of the ... prefixes [exa, peta, tera, giga and mega]. ... The use of the capital "L" as the symbol for "litre" is a change from earlier practice, which was to use the lower-case "l" or script "<script l>"'. Of course, a measurement like the litre isn't SI, so different countries may define it and it's symbol differently (the SI unit for volume is the cubic metre (`m^3').

Indeed, but if it were being done SIly, it would probably be `by'.

And then you have people complaining that Telstra have decided to define a megabyte as 1024 kilobytes and a gigabyte as 1000 megabytes (or 1000 gigabytes, depending on what information you read), and yet the go and say things like `How can Telstra decide to take a standard measurement and define it as 1000 mb?! A gigabyte is 1024 mb!'. I'm so glad we aren't using _their_ definition of a gigabyte for our 3 GB cap.
