Kilobits per Second to Bytes per Second (kbps to B/s)
1 kilobit per second (kbps) = 125 bytes per second (B/s). 1 B/s = 0.008 kbps. Example: 15 kbps = 15 × 125 = 1875 B/s.

How to Convert Kilobit per Second to Byte per Second
- 1 kbps = 125 B/s
- 1 B/s = 0.008 kbps
- Example: convert 15 kbps to B/s: 15 kbps = 15 × 125 B/s = 1875 B/s
Formula
B/s = kbps × 125
Derivation from SI units:
- 1 kbit/s = 1000 bit/s.
- 1 B/s = 8 bit/s.
- 1 kbps = 1000 bps ÷ 8 bps per B/s = 125 B/s
Both units are defined exactly, so the factor is exact. Kilobit per Second definition: kilobit per second; Byte per Second definition: byte per second.
Worked examples
- A reading of 192 kbps converts to 24000 B/s.
192 kbps × 125 = 24000 B/s - A value of 512 kbps is 64000 B/s.
512 kbps × 125 = 64000 B/s

Where it's used
Kilobits per Second are used for audio bitrates (MP3, AAC), while bytes per second appear in file transfer speeds. Both measure data transfer rate (bandwidth), so the conversion is a fixed factor.

Frequently asked questions
How many bytes per second are in 1 kilobit per second?
1 kbps = 125 B/s.
How do I convert kilobits per second to bytes per second?
Multiply the value in kbps by 125. For example, 15 kbps × 125 = 1875 B/s.
Is the kbps to B/s conversion exact?
Yes. Both units are defined exactly, and 1 kbps is exactly 125 B/s.
