binary prefix thanks for your recent edit at binary prefix some of the changes do improve the flow however your assertion about computing contexts always using powers of two is inaccurate consider storage devices hard disks floppy disks clock speeds and data speeds kbps b s in fact apart from ram and some places in an oses there is no place where binary prefixes are always used could you fix your edit about non computing contexts etc i'll do it myself if i get the time later thanks
