Kilobytes per Second to Megabits per Second (kB/s to Mbps)
1 kilobyte per second (kB/s) = 0.008 megabits per second (Mbps). 1 Mbps = 125 kB/s. Example: 15 kB/s = 15 × 0.008 = 0.12 Mbps.

How to Convert Kilobyte per Second to Megabit per Second
- 1 kB/s = 0.008 Mbps
- 1 Mbps = 125 kB/s
- Example: convert 15 kB/s to Mbps: 15 kB/s = 15 × 0.008 Mbps = 0.12 Mbps
Formula
Mbps = kB/s ÷ 125
Derivation from SI units:
- 1 kB/s = 1000 B/s = 8000 bit/s.
- 1 Mbit/s = 10⁶ bit/s.
- 1 kB/s = 8000 bps ÷ 1000000 bps per Mbps = 0.008 Mbps
Both units are defined exactly, so the factor is exact. Kilobyte per Second definition: kilobyte per second; Megabit per Second definition: megabit per second.
Worked examples
- A reading of 25 kB/s converts to 0.2 Mbps.
25 kB/s × 0.008 = 0.2 Mbps - A value of 200 kB/s is 1.6 Mbps.
200 kB/s × 0.008 = 1.6 Mbps

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

Frequently asked questions
How many megabits per second are in 1 kilobyte per second?
1 kB/s = 0.008 Mbps.
How do I convert kilobytes per second to megabits per second?
Multiply the value in kB/s by 0.008, or divide it by 125. For example, 15 kB/s × 0.008 = 0.12 Mbps.
Is the kB/s to Mbps conversion exact?
Yes. Both units are defined exactly, and 1 kB/s is exactly 0.008 Mbps.
