Hi Charlie, OK. Here's a question for you. The physical quantities corresponding to the basic SI units are length, mass, time, electric current, thermodynamic temperature, amount of substance, and luminous intensity. What physical quantity or combination of quantities would have bit or byte as a unit? Bear in mind that "information" isn't a recognized physical quantity. The closest I can think of is the dimensionless quantity one, in which cast one could put the unit "1" for bit countst and the unit "8" for bytes. I could add "bit" and "byte" definitions as "1" and "8", respectively. What do you think? > Dear UDUnits folks, > > A NASA colleague of mine stores fields that count > bits and bytes.
