Kilobytes per Second to Megabytes per Second (kB/s to MB/s)
1 kilobyte per second (kB/s) = 0.001 megabytes per second (MB/s). 1 MB/s = 1000 kB/s. Example: 15 kB/s = 15 × 0.001 = 0.015 MB/s.

How to Convert Kilobyte per Second to Megabyte per Second
- 1 kB/s = 0.001 MB/s
- 1 MB/s = 1000 kB/s
- Example: convert 15 kB/s to MB/s: 15 kB/s = 15 × 0.001 MB/s = 0.015 MB/s
Formula
MB/s = kB/s ÷ 1000
Derivation from SI units:
- 1 kB/s = 1000 B/s = 8000 bit/s.
- 1 MB/s = 10⁶ B/s = 8 Mbit/s.
- 1 kB/s = 8000 bps ÷ 8000000 bps per MB/s = 0.001 MB/s
Both units are defined exactly, so the factor is exact. Kilobyte per Second definition: kilobyte per second; Megabyte per Second definition: megabyte per second.
Worked examples
- A reading of 25 kB/s converts to 0.025 MB/s.
25 kB/s × 0.001 = 0.025 MB/s - A value of 200 kB/s is 0.2 MB/s.
200 kB/s × 0.001 = 0.2 MB/s

Where it's used
Kilobytes per Second are used for download speeds on slow links, while megabytes per second appear in download and copy speeds. Both measure data transfer rate (bandwidth), so the conversion is a fixed factor.

Frequently asked questions
How many megabytes per second are in 1 kilobyte per second?
1 kB/s = 0.001 MB/s.
How do I convert kilobytes per second to megabytes per second?
Multiply the value in kB/s by 0.001, or divide it by 1000. For example, 15 kB/s × 0.001 = 0.015 MB/s.
Is the kB/s to MB/s conversion exact?
Yes. Both units are defined exactly, and 1 kB/s is exactly 0.001 MB/s.
