Jimbuna already gave the answer, but I'll just add one bit which helps with bits and bytes:

Google is easily the most convenient "converter" out there. At least in Opera it works straight from the address bar, so you just type for example "600 megabits to megabytes" or "600 Mb to MB" and voila, it gives you the answer. Works on practically every other conversion too, you just have to be careful to give the correct units.

Yep :yep:
