Convert Gigabits per Second to Bits per Second (Gbps to bps)
1 gigabit per second (Gbps) = 1000000000 bits per second (bps). 1 bps = 1 × 10⁻⁹ Gbps. Example: 15 Gbps = 15 × 1000000000 = 15000000000 bps.

How to Convert Gigabit per Second to Bit per Second
- 1 Gbps = 1000000000 bps
- 1 bps = 1 × 10⁻⁹ Gbps
- Example: convert 15 Gbps to bps: 15 Gbps = 15 × 1000000000 bps = 15000000000 bps
Formula
bps = Gbps × 1000000000
Derivation from SI units:
- 1 Gbit/s = 10⁹ bit/s.
- One bit transferred each second.
Both units are defined exactly, so the factor is exact. Gigabit per Second definition: gigabit per second; Bit per Second definition: bit per second.
Worked examples
- A reading of 5 Gbps converts to 5000000000 bps.
5 Gbps × 1000000000 = 5000000000 bps - A value of 40 Gbps is 40000000000 bps.
40 Gbps × 1000000000 = 40000000000 bps

Where it's used
Gigabits per Second are used for ethernet and fibre links, while bits per second appear in serial ports and modems (baud-like rates). Both measure data transfer rate (bandwidth), so the conversion is a fixed factor.

Frequently asked questions
How many bits per second are in 1 gigabit per second?
1 Gbps = 1000000000 bps.
How do I convert gigabits per second to bits per second?
Multiply the value in Gbps by 1000000000. For example, 15 Gbps × 1000000000 = 15000000000 bps.
