        Because K is a much more useful default quantity to display disk
        space in than 512 (or whatever the filesytem might be) byte 
        blocks?

        Historically under BSD df and friends always used to report in K.

        Coming from an (older) BSD background I'm used to df etc always
        displaying in K. On our SGI systems we have df aliased to 'df -k'
        and du to 'du -k' to give the same effect.
