Bits per Second to Kilobytes per Second (bps to kB/s)
1 bit per second (bps) = 0.000125 kilobytes per second (kB/s). 1 kB/s = 8000 bps. Example: 15 bps = 15 × 0.000125 = 0.001875 kB/s.

How to Convert Bit per Second to Kilobyte per Second
- 1 bps = 0.000125 kB/s
- 1 kB/s = 8000 bps
- Example: convert 15 bps to kB/s: 15 bps = 15 × 0.000125 kB/s = 0.001875 kB/s
Formula
kB/s = bps ÷ 8000
Derivation from SI units:
- One bit transferred each second.
- 1 kB/s = 1000 B/s = 8000 bit/s.
Both units are defined exactly, so the factor is exact. Bit per Second definition: bit per second; Kilobyte per Second definition: kilobyte per second.
Worked examples
- A reading of 9600 bps converts to 1.2 kB/s.
9600 bps × 0.000125 = 1.2 kB/s - A value of 115200 bps is 14.4 kB/s.
115200 bps × 0.000125 = 14.4 kB/s

Where it's used
Bits per Second are used for serial ports and modems (baud-like rates), while kilobytes per second appear in download speeds on slow links. Both measure data transfer rate (bandwidth), so the conversion is a fixed factor.

Frequently asked questions
How many kilobytes per second are in 1 bit per second?
1 bps = 0.000125 kB/s.
How do I convert bits per second to kilobytes per second?
Multiply the value in bps by 0.000125, or divide it by 8000. For example, 15 bps × 0.000125 = 0.001875 kB/s.
Is the bps to kB/s conversion exact?
Yes. Both units are defined exactly, and 1 bps is exactly 0.000125 kB/s.
