Kilobits per Second to Kilobytes per Second (kbps to kB/s)
1 kilobit per second (kbps) = 0.125 kilobytes per second (kB/s). 1 kB/s = 8 kbps. Example: 15 kbps = 15 × 0.125 = 1.875 kB/s.

How to Convert Kilobit per Second to Kilobyte per Second
- 1 kbps = 0.125 kB/s
- 1 kB/s = 8 kbps
- Example: convert 15 kbps to kB/s: 15 kbps = 15 × 0.125 kB/s = 1.875 kB/s
Formula
kB/s = kbps ÷ 8
Derivation from SI units:
- 1 kbit/s = 1000 bit/s.
- 1 kB/s = 1000 B/s = 8000 bit/s.
- 1 kbps = 1000 bps ÷ 8000 bps per kB/s = 0.125 kB/s
Both units are defined exactly, so the factor is exact. Kilobit per Second definition: kilobit per second; Kilobyte per Second definition: kilobyte per second.
Worked examples
- A reading of 192 kbps converts to 24 kB/s.
192 kbps × 0.125 = 24 kB/s - A value of 512 kbps is 64 kB/s.
512 kbps × 0.125 = 64 kB/s

Where it's used
Kilobits per Second are used for audio bitrates (MP3, AAC), 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 kilobit per second?
1 kbps = 0.125 kB/s.
How do I convert kilobits per second to kilobytes per second?
Multiply the value in kbps by 0.125, or divide it by 8. For example, 15 kbps × 0.125 = 1.875 kB/s.
Is the kbps to kB/s conversion exact?
Yes. Both units are defined exactly, and 1 kbps is exactly 0.125 kB/s.
