    This is a recurring confusion, and it has been a mix-up for many years now.

    There have been attempts at changing the prefixes, but those are not so
    widely spread or used. How many uses Kibi- or Gibi-bytes in specs today?

    IEC:s definition: http://www.iec.ch/zone/si/si_bytes.htm

    (If we only had eight fingers, I'd think that problem would not exist.)
