About this tool
Convert between bits, bytes, decimal SI prefixes (kB, MB, GB, TB) and binary IEC prefixes (KiB, MiB, GiB, TiB).
Formula
value_to = value_from × (factor_from ÷ factor_to), with factors in bytes.
Worked example
1 MB = 1,000,000 B; 1 MiB = 1,048,576 B; so 1 MB ≈ 0.9537 MiB
Notes
Storage manufacturers use decimal (1 GB = 10⁹ B). Operating systems often report binary (1 GiB = 2³⁰ B). The discrepancy is why "1 TB" drives appear smaller in the OS.
