A gigabit is a unit of information or computer storage, commonly abbreviated "Gb".

1 gigabit = 10⁹ = 1 000 000 000 bits or 2³⁰ = 1 073 741 824 bits (see Binary prefix).

megabit << gigabit << terabit

The gigabit is closely related to the gibibit, which is unambiguously equal to 2³⁰ bits = 1 073 741 824 bits.
