Technically, no, they're not strictly part of SI, but they're endorsed by the BIPM for use alongside SI units (http://www.bipm.org/en/publications/si-brochure/chapter3.html). and more importantly, the BIPM forbids the use of the SI prefixes to mean powers-of-2 multipliers. B for 'byte' is an accepted usage, and unlikely to be confused with B for 'Bel' (also not an SI unit, and in any case almost never seen as anything other than dB.) I don't believe this to be a problem. If we ever have to worry about measuring anything to do with package management in dB, then we can certainly revisit the whole subject. Cheers, Matthew
