Mebibyte

The mebibyte is a multiple of the unit byte for digital information. The binary prefix mebi means 220, therefore 1 mebibyte is 1,048,576 bytes. The unit symbol for the mebibyte is MiB. The unit was established by the International Electrotechnical Commission (IEC) in 2000. It was designed to replace the megabyte used in some computer science contexts to mean 220 bytes, which is similar to but conflicts with the SI definition of the prefix mega (106).
