Convert Gigabits to Bits (Gbit to bit)
1 gigabit (Gbit) = 1000000000 bits (bit). 1 bit = 1 × 10⁻⁹ Gbit. Example: 15 Gbit = 15 × 1000000000 = 15000000000 bit.

How to Convert Gigabit to Bit
- 1 Gbit = 1000000000 bit
- 1 bit = 1 × 10⁻⁹ Gbit
- Example: convert 15 Gbit to bit: 15 Gbit = 15 × 1000000000 bit = 15000000000 bit
Formula
bit = Gbit × 1000000000
Derivation from SI units:
- 1 Gbit = 10⁹ bits.
- The basic unit of information: one binary digit, 0 or 1.
Both units are defined exactly, so the factor is exact. Gigabit definition: gigabit; Bit definition: bit.
Worked examples
- A reading of 16 Gbit converts to 16000000000 bit.
16 Gbit × 1000000000 = 16000000000 bit - A value of 128 Gbit is 128000000000 bit.
128 Gbit × 1000000000 = 128000000000 bit

Where it's used
Gigabits are used for DRAM and NAND flash chip densities, while bits appear in network speeds (bits per second). Both measure amount of digital information, so the conversion is a fixed factor.
