Data Storage Converter

Convert digital storage: bits, bytes, KB, MB, GB, TB and the binary units KiB, MiB, GiB and TiB.

KB = B × 0.001

Data Storage units and how they relate

KB, MB, GB and TB are decimal (powers of 1,000) as defined by the SI and used by drive makers. KiB, MiB, GiB and TiB are binary (powers of 1,024, IEC 80000-13), which is what Windows reports as "GB".
