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

Byte (B): Eight bits, the basic unit of computer storage and the size of one character in many encodings.
Kibibyte (KiB): 1,024 bytes (2^10), the binary unit defined by the IEC in 1998.
