Convert Bits per Second to Kilobits per Second (bps to kbps)
1 bit per second (bps) = 0.001 kilobits per second (kbps). 1 kbps = 1000 bps. Example: 15 bps = 15 × 0.001 = 0.015 kbps.

How to Convert Bit per Second to Kilobit per Second
- 1 bps = 0.001 kbps
- 1 kbps = 1000 bps
- Example: convert 15 bps to kbps: 15 bps = 15 × 0.001 kbps = 0.015 kbps
Formula
kbps = bps ÷ 1000
Derivation from SI units:
- One bit transferred each second.
- 1 kbit/s = 1000 bit/s.
Both units are defined exactly, so the factor is exact. Bit per Second definition: bit per second; Kilobit per Second definition: kilobit per second.
Worked examples
- A reading of 9600 bps converts to 9.6 kbps.
9600 bps × 0.001 = 9.6 kbps - A value of 115200 bps is 115.2 kbps.
115200 bps × 0.001 = 115.2 kbps

Where it's used
Bits per Second are used for serial ports and modems (baud-like rates), 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 bit per second?
1 bps = 0.001 kbps.
How do I convert bits per second to kilobits per second?
Multiply the value in bps by 0.001, or divide it by 1000. For example, 15 bps × 0.001 = 0.015 kbps.
Is the bps to kbps conversion exact?
Yes. Both units are defined exactly, and 1 bps is exactly 0.001 kbps.
