I work for an ISP as a net engineer, and we distinguish between our pipes (measured in Mb/s) and our server memory/disk capacity (measured in MB or GB). > In my younger days, no one was particularly interested in bits, and Mb meant > megabyte.

At this stage I was reading British electronics magazines (Elektor and the like), and they are usually pretty good at sticking to standards. I have never actually _seen_ any document that stated with great authority that "this means 'bits' and that means 'bytes'". That was left either as an exercise for the reader, or was listed in one of those "jargon for the computing idiot" lists that came out every now-and-then. (hmm.. thinks - (just had a look) there is no reference in the Jargon File) > Still, should I quibble over this when I can still buy cans of food marked > 450gm. Gram metres must be useful for something, but not measuring food. :-) I once bought pills (Aspirin I think) that claimed to have a ton of the stuff per tablet (1Mg) :-).
