1 gigabit = 10⁹ = 1,000,000,000 bits (which is equal to 125 decimal megabytes) or 2³⁰ (= 1024 Mb = 1,048,576 Kb) = 1,073,741,824 bits (which is equal to 128 binary megabytes) (see Binary prefix).

The gigabit is closely related to the gibibit, which is unambiguously equal to 2³⁰ bits = 1,073,741,824 bits. A gibibit is a unit of information or computer storage. ...

Note that the difference between a billion bits and a gibibit is fully 7%. This is sufficient to make it economically compelling to represent certain classes of storage devices in (true) gigabits or gigabytes rather than gibibits/gibibytes. RAM and Flash chips are usually required to have a capacity that is a power of two, but other devices like disk drives need not.
