The zebibit is a multiple of the bit, a unit of digital information storage, prefixed by the standards-based multiplier zebi (symbol Zi), a binary prefix meaning 2⁷⁰.^[1][2] The unit symbol of the zebibit is Zibit.

1 zebibit = 2⁷⁰ bits = 1180591620717411303424bits = 1024 exbibits^[3]

The prefix zebi was originally not a part of the system of binary prefixes, but was added together with the prefix yobi by the International Electrotechnical Commission in August 2005.^[4]
