Kilobytes per Second to Gigabits per Second (kB/s to Gbps)
1 kilobyte per second (kB/s) = 0.000008 gigabits per second (Gbps). 1 Gbps = 125000 kB/s. Example: 15 kB/s = 15 × 0.000008 = 0.00012 Gbps.

How to Convert Kilobyte per Second to Gigabit per Second
- 1 kB/s = 0.000008 Gbps
- 1 Gbps = 125000 kB/s
- Example: convert 15 kB/s to Gbps: 15 kB/s = 15 × 0.000008 Gbps = 0.00012 Gbps
Formula
Gbps = kB/s ÷ 125000
Derivation from SI units:
- 1 kB/s = 1000 B/s = 8000 bit/s.
- 1 Gbit/s = 10⁹ bit/s.
- 1 kB/s = 8000 bps ÷ 1000000000 bps per Gbps = 0.000008 Gbps
Both units are defined exactly, so the factor is exact. Kilobyte per Second definition: kilobyte per second; Gigabit per Second definition: gigabit per second.
Worked examples
- A reading of 25 kB/s converts to 0.0002 Gbps.
25 kB/s × 0.000008 = 0.0002 Gbps - A value of 200 kB/s is 0.0016 Gbps.
200 kB/s × 0.000008 = 0.0016 Gbps

Where it's used
Kilobytes per Second are used for download speeds on slow links, while gigabits per second appear in ethernet and fibre links. Both measure data transfer rate (bandwidth), so the conversion is a fixed factor.

Frequently asked questions
How many gigabits per second are in 1 kilobyte per second?
1 kB/s = 0.000008 Gbps.
How do I convert kilobytes per second to gigabits per second?
Multiply the value in kB/s by 0.000008, or divide it by 125000. For example, 15 kB/s × 0.000008 = 0.00012 Gbps.
Is the kB/s to Gbps conversion exact?
Yes. Both units are defined exactly, and 1 kB/s is exactly 0.000008 Gbps.
