Petabit
The petabit is a multiple of the unit bit for digital information or computer storage. The prefix peta (symbol P) is defined in the International System of Units (SI) as a multiplier of 1015 (1 quadrillion, short scale),〔(The NIST Reference on Constants, Units, and Uncertainty: ''SI prefixes'' )〕 and therefore :1 petabit = = = 1000 terabits. The petabit has the unit symbol Pbit or Pb. The petabit is closely related to the pebibit, a unit multiple derived from the binary prefix pebi of the same order of magnitude,〔(The NIST Reference on Constants, Units, and Uncertainty: ''Prefixes for binary multiples'' )〕 which is equal to = , or approximately 13% larger than the petabit. ==See also==
