The kibibit is a multiple of the bit, a unit of digital information storage, prefixed by the standards-based multiplier kibi (symbol Ki), a binary prefix meaning 2¹⁰.^[1][2] The unit symbol of the kibibit is Kibit.

1 kibibit = 2¹⁰ bits = 1024 bits^[3]

The kibibit has existed since 1998 and is closely related to the kilobit, which is equal to 10³ bits = 1000 bits.

The binary prefixes form part of the International System of Quantities (ISQ).^[4]
