Because kilobits are ambiguous and misuse the prefix "kilo" as defined by the International System of Units, the International Electrotechnical Commission established Kibibits in 1998.

A kibibit is always equal to 2^10, or 1,024 bits.

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

Very similar to Kilobits, which use a less exact prefix established by the International System of Units (SI) but are used much more commonly.
