Decimal vs binary: KB, MB and GB use powers of 1,000 (SI), while KiB, MiB and GiB use powers of 1,024. Storage makers use decimal units; many operating systems and memory sizes use binary ones, which is why a "500 GB" drive shows less space.

About the units

Megabit (Mbit): 1,000,000 bits; internet providers advertise connection speeds in megabits per second.
Gigabit (Gbit): 1,000,000,000 bits; used for fast networks and fibre connections.
