Why convert MB to MiB?
Decimal units (KB, MB, GB) are used by drive makers and networks; binary units (KiB, MiB, GiB) by operating systems and RAM. The roughly 7% gap per step is why drives look 'smaller' than advertised.
Storage makers use decimal units: 1 GB = 1,000 MB = 1,000,000,000 bytes. Operating systems often show binary units, where 1 GiB = 1,024 MiB — which is why a '1 TB' drive appears as about 931 GiB (IEC 80000-13).
