OS X and iOS are the weird (but correct) ones (Destiny)

Apple changed how file sizes and free space were reported back in OS X 10.6 (Snow Leopard), moving to a base-10 numbering. The actual number of bits is no different, it’s just that the OS does base-10 math instead of base-2 math. This is true for iOS as well, apparently:

As far as any other “major operating systems” go, however: nope, they all use base-2.

Technically speaking, everyone using base-2 calculations should report file sizes in KiB, MiB, and GiB, while base-10 should report KB, MB, and GB. Here’s a chart from the Wikipedia page on Binary Prefixes:
