Kilobytes per Second to Mebibytes per Second (kB/s to MiB/s)

Formula

MiB/s = kB/s × 0.0009536743164063

or MiB/s = kB/s ÷ 1048.576

Derivation from SI units:

• 1 kB/s = 1000 B/s = 8000 bit/s.
• 1 MiB/s = 1,048,576 B/s.
• 1 kB/s = 8000 bps ÷ 8388608 bps per MiB/s = 0.0009536743164063 MiB/s

Both units are defined exactly, so the factor is exact. Kilobyte per Second definition: kilobyte per second; Mebibyte per Second definition: mebibyte per second.

Worked examples

1. A reading of 25 kB/s converts to 0.02384185791 MiB/s.
   25 kB/s × 0.0009536743164 = 0.02384185791 MiB/s
2. A value of 200 kB/s is 0.1907348633 MiB/s.
   200 kB/s × 0.0009536743164 = 0.1907348633 MiB/s

Where it's used

Kilobytes per Second are used for download speeds on slow links, while mebibytes per second appear in file copy dialogs. Both measure data transfer rate (bandwidth), so the conversion is a fixed factor.
