The yobibit is a multiple of the bit, a unit of digital information storage, prefixed by the standards-based multiplier yobi (symbol Yi), a binary prefix meaning 2⁸⁰. The unit symbol of the yobibit is Yibit.^[1][2]

1 yobibit = 2⁸⁰ bits = 1208925819614629174706176bits = 1024 zebibits^[3]

The prefixes zebi and yobi were originally not part of the system of binary prefixes, but were added by the International Electrotechnical Commission in August 2006.^[4]
