Well, it is wrong. Besides, kilo isn't consistently used to mean the number 1024 even in IT. Disk manufactureres usually use kilo and mega correctly, while operating systems tend to use the wrong meaning. Telecoms has always used kilo correctly, so transmission speeds are measured in kilobits, megabits and gigabits, where the prefixes do mean a power of ten. Clock speeds are measured correctly. etc. To clean up this long standing mess, several standards bodies recommend the use of a new binary prefix when referring to powers of two. Having a notational prefix, a constant, which can mean one thing for scientists in most fields, and another for sloppy IT workers, is a receipe for disaster and misunderstanding. To avoid confusion these standards bodies recommend the use of a completely different name (kibi) for the binary prefixes, not just "binary kilobytes" which still use the prefix kilo.
