Mebibyte

The mebibyte (symbol: MiB) is a unit of information or computer data storage.

1 MiB = 2²⁰ bytes = 1,048,576 bytes = 1,024 kibibytes

The mebibyte is closely related to the megabyte (MB). The megabyte refers to 10⁶ bytes = 1 000 000 bytes (see binary prefix for background). The two units are relatively close together, but mistaking the two has nevertheless led to problems.

The unit MiB 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 becoming more common.

One mebibyte equals 1024 (= 2¹⁰) kibibytes, and 1024 mebibytes equal one gibibyte.
