    And when you do have base 2 numbers then multiplication/division gives other nice base 2 numbers like 10 MiB / 2 KiB = 5 KiB.

    The units cancel, so you get 5K er... 5*1024 = 5120.

    My favorite solution to the issue is to treat GB, MB, and KB as special units whose meanings are 1024MB, 1024KB, and 1024B, respectively. That's what they've meant for decades, and I'm not going fiddle with giving them two incompatible meanings now. IMO if powers of two don't matter in a particular context, it's cleanest to use Gb, Mb, and kb, SI units referring to 1000Mb, 1000kb, and 1000b (bits), respectively. Bits are a fairly fundamental unit.
