Gigabits per Second to Kilobits per Second (Gbps to kbps)
1 gigabit per second (Gbps) = 1000000 kilobits per second (kbps). 1 kbps = 0.000001 Gbps. Example: 15 Gbps = 15 × 1000000 = 15000000 kbps.

How to Convert Gigabit per Second to Kilobit per Second
- 1 Gbps = 1000000 kbps
- 1 kbps = 0.000001 Gbps
- Example: convert 15 Gbps to kbps: 15 Gbps = 15 × 1000000 kbps = 15000000 kbps
Formula
kbps = Gbps × 1000000
Derivation from SI units:
- 1 Gbit/s = 10⁹ bit/s.
- 1 kbit/s = 1000 bit/s.
- 1 Gbps = 1000000000 bps ÷ 1000 bps per kbps = 1000000 kbps
Both units are defined exactly, so the factor is exact. Gigabit per Second definition: gigabit per second; Kilobit per Second definition: kilobit per second.
Worked examples
- A reading of 5 Gbps converts to 5000000 kbps.
5 Gbps × 1000000 = 5000000 kbps - A value of 40 Gbps is 40000000 kbps.
40 Gbps × 1000000 = 40000000 kbps

Where it's used
Gigabits per Second are used for ethernet and fibre links, while kilobits per second appear in audio bitrates (MP3, AAC). Both measure data transfer rate (bandwidth), so the conversion is a fixed factor.

Frequently asked questions
How many kilobits per second are in 1 gigabit per second?
1 Gbps = 1000000 kbps.
How do I convert gigabits per second to kilobits per second?
Multiply the value in Gbps by 1000000. For example, 15 Gbps × 1000000 = 15000000 kbps.
Is the Gbps to kbps conversion exact?
Yes. Both units are defined exactly, and 1 Gbps is exactly 1000000 kbps.
