Convert between bit / Byte / KB / MB / GB / TB / PB / EB with both binary (1024) and decimal (1000) standards.
Type a value, pick the unit, and the table updates live with conversions for both standards. Binary (IEC): 1 KiB = 1024 B, 1 MiB = 1024 KiB — the convention Windows uses for file sizes. Decimal (SI): 1 KB = 1000 B, 1 MB = 1000 KB — used by storage manufacturers for disk / SSD capacities. Switch tabs to focus one standard. A bit is a single 0/1; a Byte is 8 bits.
