Kilobytes per Second to Kilobits per Second (kB/s to kbps)
1 kilobyte per second (kB/s) = 8 kilobits per second (kbps). 1 kbps = 0.125 kB/s. Example: 15 kB/s = 15 × 8 = 120 kbps.

How to Convert Kilobyte per Second to Kilobit per Second
- 1 kB/s = 8 kbps
- 1 kbps = 0.125 kB/s
- Example: convert 15 kB/s to kbps: 15 kB/s = 15 × 8 kbps = 120 kbps
Formula
kbps = kB/s × 8
Derivation from SI units:
- 1 kB/s = 1000 B/s = 8000 bit/s.
- 1 kbit/s = 1000 bit/s.
- 1 kB/s = 8000 bps ÷ 1000 bps per kbps = 8 kbps
Both units are defined exactly, so the factor is exact. Kilobyte per Second definition: kilobyte per second; Kilobit per Second definition: kilobit per second.
Worked examples
- A reading of 25 kB/s converts to 200 kbps.
25 kB/s × 8 = 200 kbps - A value of 200 kB/s is 1600 kbps.
200 kB/s × 8 = 1600 kbps

Frequently asked questions
How many kilobits per second are in 1 kilobyte per second?
1 kB/s = 8 kbps.
How do I convert kilobytes per second to kilobits per second?
Multiply the value in kB/s by 8. For example, 15 kB/s × 8 = 120 kbps.
Is the kB/s to kbps conversion exact?
Yes. Both units are defined exactly, and 1 kB/s is exactly 8 kbps.
