The '''gigabit''' is a multiple of the unit [[bit]] for digital [[information]] or [[computer storage]]. The prefix [[giga-|giga]] (symbol G) is defined in the [[International System of Units]] (SI) as a multiplier of 10<sup>9</sup> (1 billion, [[short scale]]),<ref>[http://physics.nist.gov/cuu/Units/prefixes.html The NIST Reference on Constants, Units, and Uncertainty: ''SI prefixes'']</ref> and therefore |
|||
:1 gigabit = {{gaps|10<sup>9</sup>|bits}} = {{gaps|1|000|000|000|bits}}. |
|||
The gigabit has the unit symbol '''Gbit''' or '''Gb'''. |
|||
Using the common [[byte]] size of 8 bits, 1 Gbit is equal to 125 [[megabyte]]s (MB) or approximately 119 [[mebibyte]]s (MiB). |
|||
The gigabit is closely related to the [[gibibit]], a unit multiple derived from the [[binary prefix]] [[gibi-|gibi]] (symbol Gi) of the same order of magnitude,<ref>[http://physics.nist.gov/cuu/Units/binary.html The NIST Reference on Constants, Units, and Uncertainty: ''Prefixes for binary multiples'']</ref> which is equal to {{gaps|2<sup>30</sup>|bits}} = {{gaps|1|073|741|824|bits}}, or approximately 7% larger than the gigabit. |
