Kilobytes per Second to Bits per Second (kB/s to bps)
1 kilobyte per second (kB/s) = 8000 bits per second (bps). 1 bps = 0.000125 kB/s. Example: 15 kB/s = 15 × 8000 = 120000 bps.

How to Convert Kilobyte per Second to Bit per Second
- 1 kB/s = 8000 bps
- 1 bps = 0.000125 kB/s
- Example: convert 15 kB/s to bps: 15 kB/s = 15 × 8000 bps = 120000 bps
Formula
bps = kB/s × 8000
Derivation from SI units:
- 1 kB/s = 1000 B/s = 8000 bit/s.
- One bit transferred each second.
Both units are defined exactly, so the factor is exact. Kilobyte per Second definition: kilobyte per second; Bit per Second definition: bit per second.
Worked examples
- A reading of 25 kB/s converts to 200000 bps.
25 kB/s × 8000 = 200000 bps - A value of 200 kB/s is 1600000 bps.
200 kB/s × 8000 = 1600000 bps

Where it's used
Kilobytes per Second are used for download speeds on slow 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 kilobyte per second?
1 kB/s = 8000 bps.
How do I convert kilobytes per second to bits per second?
Multiply the value in kB/s by 8000. For example, 15 kB/s × 8000 = 120000 bps.
Is the kB/s to bps conversion exact?
Yes. Both units are defined exactly, and 1 kB/s is exactly 8000 bps.
