Zettabit
The zettabit is a multiple of the unit bit for digital information or computer storage. The prefix zetta (symbol Z) is defined in the International System of Units (SI) as a multiplier of 1021 (1 sextillion, short scale),〔(The NIST Reference on Constants, Units, and Uncertainty: ''SI prefixes'' )〕 and therefore :1 zettabit = = = 1000 exabits. The zettabit has the unit symbol Zbit or Zb. The zettabit is closely related to the zebibit, a unit multiple derived from the binary prefix zebi of the same order of magnitude,〔(The NIST Reference on Constants, Units, and Uncertainty: ''Prefixes for binary multiples'' )〕 which is equal to = , or approximately 18% larger than the zettabit. ==See also==
