Kibibytes per Second to Kilobytes per Second (KiB/s to kB/s)
1 kibibyte per second (KiB/s) = 1.024 kilobytes per second (kB/s). 1 kB/s = 0.9765625 KiB/s. Example: 15 KiB/s = 15 × 1.024 = 15.36 kB/s.

How to Convert Kibibyte per Second to Kilobyte per Second
- 1 KiB/s = 1.024 kB/s
- 1 kB/s = 0.9765625 KiB/s
- Example: convert 15 KiB/s to kB/s: 15 KiB/s = 15 × 1.024 kB/s = 15.36 kB/s
Formula
kB/s = KiB/s × 1.024
Derivation from SI units:
- 1 KiB/s = 1024 B/s.
- 1 kB/s = 1000 B/s = 8000 bit/s.
- 1 KiB/s = 8192 bps ÷ 8000 bps per kB/s = 1.024 kB/s
Both units are defined exactly, so the factor is exact. Kibibyte per Second definition: kibibyte per second; Kilobyte per Second definition: kilobyte per second.
Worked examples
- A reading of 25 KiB/s converts to 25.6 kB/s.
25 KiB/s × 1.024 = 25.6 kB/s - A value of 200 KiB/s is 204.8 kB/s.
200 KiB/s × 1.024 = 204.8 kB/s

Where it's used
Kibibytes per Second are used for linux command-line 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 kibibyte per second?
1 KiB/s = 1.024 kB/s.
How do I convert kibibytes per second to kilobytes per second?
