B to MB Converter

Convert bytes (B) to megabytes (MB). 1 B = 0.000001 MB.

How to convert B to MB

Bytes and megabytes are both decimal (power-of-1000) units defined by the SI standard. One B is 1 bytes and one MB is 1,000,000 bytes, so multiply a B value by 0.000001 to get MB.

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.
