I believe at one time it was. Also my file size descriptions use the 1024 ratio in going from kbytes the Mbytes.

Yes, files do. Interestingly (or maybe not ) HD manufacturers cheat and use 1000 instead of 1024. 1TB in their currency is 1000,000,000,000 bytes, or 931.3GB in real money.
The reason bitrates are 1000 based is because the clock frequencies to drive those rates would be really weird!
Also, K was originally 1000, M 1000,000, but the computer world misused it to mean 1024 and 1048576 because they are convenient a bit boundaries (which is the HD manufacturers argument for using 1000).
There's probably a wiki page that explains it better than me....
