A mebibyte (a contraction of mega binary byte) is a unit of information or computer storage, abbreviated MiB.
The mebibyte is closely related to the megabyte (MB), which can either be a synonym for mebibyte, or refer to 106 bytes = 1,000,000 bytes, depending on context (see binary prefix for background). The two numbers are relatively close together, but mistaking the two has nevertheless occasionally led to problems.
The unit was defined by the International Electrotechnical Commission (IEC) in December 1998. Use of mebibyte and related units is strongly endorsed by IEEE and CIPM and is slowly becoming more common.
One mebibyte equals 1024 (= 210) kibibytes, and 1024 mebibytes equal one gibibyte.
Mibibyte is a common misspelling, presumably from the "i" in the abbreviation or confusion about how the surrounding prefixes (i.e. "kibi" and "gibi") were actually formed. The "i" is actually from the end of the prefix. Tebi- and pebi- are similarly abbreviated Ti- and Pi-, but they are not usually misspelled, as storage sizes (and corresponding terms) currently are only this large in specialized situations.
