MiB to MB Converter
Convert mebibytes (MiB) to megabytes (MB). 1 MiB = 1.048576 MB.
How to convert MiB to MB
Mebibytes and megabytes are both different kinds of units. One MiB is 1,048,576 bytes and one MB is 1,000,000 bytes, so multiply a MiB value by 1.048576 to get MB.
Watch out: this conversion crosses between decimal and binary units. MiB is based on 1024 while MB is based on 1000 - they are close but not equal, which is why a "500 GB" drive shows up as roughly 465 GiB in your operating system.

KB vs KiB: 1000 or 1024?
SI units (KB, MB, GB, TB) are powers of 1000. Binary units (KiB, MiB, GiB, TiB) are powers of 1024. Storage manufacturers advertise in decimal units while operating systems often report binary units, which is why drives appear "smaller" than advertised. When precision matters, name the unit explicitly.
