gigabit
The gigabit is a multiple of the unit bit for digital information or computer storage. The prefix giga (symbol G) is defined in the International System of Units (SI) as a multiplier of 109 (1 billion, short scale),〔(The NIST Reference on Constants, Units, and Uncertainty: ''SI prefixes'' )〕 and therefore :1 gigabit = = . The gigabit has the unit symbol Gbit or Gb. Using the common byte size of 8 bits, 1 Gbit is equal to 125 megabytes (MB) or approximately 119 mebibytes (MiB). The gigabit is closely related to the gibibit, a unit multiple derived from the binary prefix gibi (symbol Gi) of the same order of magnitude,〔(The NIST Reference on Constants, Units, and Uncertainty: ''Prefixes for binary multiples'' )〕 which is equal to = , or approximately 7% larger than the gigabit. ==See also==
