1 yobibit = 280 bits = 1208925819614629174706176bits = 1024 zebibits
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.
The binary prefixes are not part of the International System of Units (SI).
