The two units
Megabyte (MB). One million bytes. Windows shows sizes in units of 1,048,576 bytes but labels them MB.
Kibibyte (KiB). 1,024 bytes (2¹⁰), the binary unit defined by the IEC in 1998.
Because both units are defined in terms of the same base unit, the factor 976.5625 is exact, not a rounded measurement.
