Take a look at the properties of a file in Nautilus. It will tell you
a file is x MB, and y bytes.

I have a file here of "701.2 MB", which is "735270912 bytes". Now, if
it really *were* 701.2 MB, then it would be 701200000 bytes. So that's
clearly base 2, which should be MiB.

While that may be true, the most useful thing about base 10 is that
normal humans can actually understand it. We cannot calculate using a
binary number system. Base 2 is not useful for anything, except
sometimes in programming.
