that's a bit pedantic, ya know... the number only means something to people who know the system even a little bit, and they'll immediately translate to the proper unit because 10 milli-hashes per second makes no sense. Unless you're mining by hand.
It's like ranting that people talk about "10mb" files. Or "100gb" or "100GB" drives. When they're technically "93.1GiB" drives ("gibibyte" [1],[2], or [3]).
