Kibibyte

Because kilobytes are ambiguous and misuse the prefix "kilo" as defined by the International System of Units, the International Electrotechnical Commission established Kibibytes in 2000.

A kibibyte is always equal to 2^10, or 1,024 bytes.

Kibibytes are 1,024 bytes and precede mebi, gibi, tebi, pebi, exbi, zebi and yobi in byte measurement.
