How to Convert Gigabit to Bit

To convert from Gigabit (Gb) to Bit (b), multiply the value by 1,073,741,824.

Formula: b = Gb × 1.073742e+9

Reverse: Gb = b × 9.313226e-10

Step-by-Step Example

Start with your value in Gigabit. For example: 5 Gb
Multiply by the conversion factor: 5 x 1,073,741,824
The result is: 5,368,709,120 b

About Gigabit

The gigabit (Gb) is a unit of digital storage. One gigabit equals 1.342177 × 10^+8 bytes. UnitConvertLab converts it against every other data unit using this exact definition, so results are reproducible to full double precision rather than rounded lookup tables.

Common uses: data calculations, engineering and science, education.

About Bit

The bit (b) is a unit of digital storage. One bit equals 0.125 bytes. UnitConvertLab converts it against every other data unit using this exact definition, so results are reproducible to full double precision rather than rounded lookup tables.

Common uses: data calculations, engineering and science, education.
