If we can just make it so that a meter is 102.4 centimeters, we'll all be okay.

Well, it makes sense based on SI (metric) standards which were designed to handle base-10 metrics, e.g. meters, kilometers, etc. But, it does not make sense when mixed with the term "byte" since a byte is base-2, i.e. binary. Sure, we could all say "Okay, a 'kilobyte' is technically 1000 bytes", but then the term kilobyte just becomes a useless term with no practical application because you're never going to actually do anything with 1000 bytes, your computer is only going to work in binary. Good luck trying to get Oracle to give you an 8000 byte block :) So, I agree the term kilobyte is technically a misnomer, but I think it is pointless trying to change it now.

That does unfortunately make sense.

"kibibyte" for 1024 bytes, and that a kilobyte should = 1000 bytes.
