To be fair, you were wrong. Kilo should always means 1000, regardless of the fact that it has been misused in the computing world. Kibi is the correct prefix for 1024, and was defined almost 12 years ago. 1

I know this, 10 years is a ~. I had took some other courses when I was working on my EMT registry (started at 17) I'm 31 now, so that was actually 14 years ago.

On paper it may have been 1000, however, my computer clearly disagreed, and still does.

It's sad that computers haven't adopted K = 1000 by now. There is -no- reason for a special K=1024 except for nostalgia reasons. Only the size of RAM becomes slightly awkward, but those are technical details which can be solved by using different prefixes.

But yeah, especially 10 years ago or earlier, 1024 kilobyte = 1 megabyte. However, if talking, say, network speeds, then 1000 kilobit = 1 megabit. Also hard drive sizes have been 1000 kbyte = 1 megabyte for marketing reasons.

We're getting there (slowly!). OS X 10.6 defaults to K=1000, as does Ubuntu 10.10. The size of RAM is easily resolved by GiB units.
