Bytes per Second to Kilobits per Second (B/s to kbps)
1 byte per second (B/s) = 0.008 kilobits per second (kbps). 1 kbps = 125 B/s. Example: 15 B/s = 15 × 0.008 = 0.12 kbps.

How to Convert Byte per Second to Kilobit per Second
- 1 B/s = 0.008 kbps
- 1 kbps = 125 B/s
- Example: convert 15 B/s to kbps: 15 B/s = 15 × 0.008 kbps = 0.12 kbps
Formula
kbps = B/s ÷ 125
Derivation from SI units:
- 1 B/s = 8 bit/s.
- 1 kbit/s = 1000 bit/s.
- 1 B/s = 8 bps ÷ 1000 bps per kbps = 0.008 kbps
Both units are defined exactly, so the factor is exact. Byte per Second definition: byte per second; Kilobit per Second definition: kilobit per second.
Worked examples
- A reading of 100 B/s converts to 0.8 kbps.
100 B/s × 0.008 = 0.8 kbps - A value of 1024 B/s is 8.192 kbps.
1024 B/s × 0.008 = 8.192 kbps

Where it's used
Bytes per Second are used for file transfer speeds, 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 byte per second?
1 B/s = 0.008 kbps.
How do I convert bytes per second to kilobits per second?
Multiply the value in B/s by 0.008, or divide it by 125. For example, 15 B/s × 0.008 = 0.12 kbps.
Is the B/s to kbps conversion exact?
Yes. Both units are defined exactly, and 1 B/s is exactly 0.008 kbps.
