Bytes per Second to Kilobytes per Second (B/s to kB/s)
1 byte per second (B/s) = 0.001 kilobytes per second (kB/s). 1 kB/s = 1000 B/s. Example: 15 B/s = 15 × 0.001 = 0.015 kB/s.

How to Convert Byte per Second to Kilobyte per Second
- 1 B/s = 0.001 kB/s
- 1 kB/s = 1000 B/s
- Example: convert 15 B/s to kB/s: 15 B/s = 15 × 0.001 kB/s = 0.015 kB/s
Formula
kB/s = B/s ÷ 1000
Derivation from SI units:
- 1 B/s = 8 bit/s.
- 1 kB/s = 1000 B/s = 8000 bit/s.
- 1 B/s = 8 bps ÷ 8000 bps per kB/s = 0.001 kB/s
Both units are defined exactly, so the factor is exact. Byte per Second definition: byte per second; Kilobyte per Second definition: kilobyte per second.
Worked examples
- A reading of 100 B/s converts to 0.1 kB/s.
100 B/s × 0.001 = 0.1 kB/s - A value of 1024 B/s is 1.024 kB/s.
1024 B/s × 0.001 = 1.024 kB/s

Where it's used
Bytes per Second are used for file transfer speeds, 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 byte per second?
1 B/s = 0.001 kB/s.
How do I convert bytes per second to kilobytes per second?
Multiply the value in B/s by 0.001, or divide it by 1000. For example, 15 B/s × 0.001 = 0.015 kB/s.
Is the B/s to kB/s conversion exact?
Yes. Both units are defined exactly, and 1 B/s is exactly 0.001 kB/s.
