Convert bits, bytes and decimal or binary multiples such as MB, GB, MiB and GiB.
Units of data
1 byte (B) = 8 bits. Decimal prefixes (kB, MB, GB) multiply by 1,000: 1 MB = 1,000,000 B. Binary units (KiB, MiB, GiB) multiply by 1,024: 1 MiB = 1,048,576 B. Storage makers use decimal units, while some systems show binary values labelled “GB”, which is why a drive can look smaller than advertised.
Conversion factors
1 MB = 0.001 GB
1 GB = 1,000 MB
