Mebibytes per Second to Kilobytes per Second (MiB/s to kB/s)
1 mebibyte per second (MiB/s) = 1048.576 kilobytes per second (kB/s). 1 kB/s = 0.0009536743164 MiB/s. Example: 15 MiB/s = 15 × 1048.576 = 15728.64 kB/s.

How to Convert Mebibyte per Second to Kilobyte per Second
- 1 MiB/s = 1048.576 kB/s
- 1 kB/s = 0.0009536743164 MiB/s
- Example: convert 15 MiB/s to kB/s: 15 MiB/s = 15 × 1048.576 kB/s = 15728.64 kB/s
Formula
kB/s = MiB/s × 1048.576
Derivation from SI units:
- 1 MiB/s = 1,048,576 B/s.
- 1 kB/s = 1000 B/s = 8000 bit/s.
- 1 MiB/s = 8388608 bps ÷ 8000 bps per kB/s = 1048.576 kB/s
Both units are defined exactly, so the factor is exact. Mebibyte per Second definition: mebibyte per second; Kilobyte per Second definition: kilobyte per second.
Worked examples
- A reading of 25 MiB/s converts to 26214.4 kB/s.
25 MiB/s × 1048.576 = 26214.4 kB/s - A value of 200 MiB/s is 209715.2 kB/s.
200 MiB/s × 1048.576 = 209715.2 kB/s
