The problem was that IT handled prefixes as powers of 2. So the kb were 1024*8 bits, the MB were 2^20*8 bits and so on. That is why you've ment 1Gb=2^30*8 bits. AFAIK they changed the international convention from KB,MB,GB... to KiB, MiB, GiB so that now the old k/M/G are exactly in SI-style (1000/1000000/1000000000) and Ki/Mi/Gi stand for the IT-version (powers of 2: 1024/2^20/2^30). -- mail: adi@thur.de http://adi.thur.de PGP: v2-key via keyserver Reset-Knopf?

Sorry to answer to this one specific mail out of a rather large number that I received on the subject (it just happened to be the last I saw). Believe me, I do know the difference between 2 and 10 based definitions of of Kilo, Mega, Giga, Tera and so on. It was just meant to show why the question has arised in the first place. I wonder why not one of the respondents noticed the smiley at the end of what I wrote? ^ permalink raw reply [flat|nested] 6+ messages in thread
