In my opinion any time KB, MB, GB, etc, uses multiples of 1000 it is wrong! It all started by those damn hard drive manufacturers to make their drives appear larger than they really are.
Perhaps I’m just a binary purist. I appreciate that MiB, GiB, TiB, takes away the ambiguity and clearly identifies 2^10 multiples, but it’s a shame that they had to be invented in the first place.
