What does MB mean?

MegaByte (MB) is a unit of digital information or computer storage. Although the prefix mega- means 1000000 or (10⁶), the term MegaByte has historically been used to refer to either 10⁶ bytes or 2²⁰ bytes, dependent upon context, in the fields of computer science and information technology.

Base 10
1 MB = 10⁶ bytes = 1000² bytes = 1000000 bytes

Base 2
1 MB = 1 Mebibyte (MiB) = 2²⁰ = 1024² bytes = 1048576 bytes

Note:
Technically a MegaByte (MB) is a power of ten, while a mebibyte (MiB) is a power of two, appropriate for binary machines.
