Can someone please enlighten me as to current usage of KB and Kb I had always thought that Kb meant Kilobit and KB Kilobyte. Is this in fact right or have I been labouring under a misapprehension? I could never really see the need to measure things in Kilobits and lots of apps seem to use Kb to refer to Kilobytes. Is this now the accepted usage? I have no axe to grind either way. I would just like to know.
