Megabits per Second to Bytes per Second (Mbps to B/s)
1 megabit per second (Mbps) = 125000 bytes per second (B/s). 1 B/s = 0.000008 Mbps. Example: 15 Mbps = 15 × 125000 = 1875000 B/s.

How to Convert Megabit per Second to Byte per Second
- 1 Mbps = 125000 B/s
- 1 B/s = 0.000008 Mbps
- Example: convert 15 Mbps to B/s: 15 Mbps = 15 × 125000 B/s = 1875000 B/s
Formula
B/s = Mbps × 125000
Derivation from SI units:
- 1 Mbit/s = 10⁶ bit/s.
- 1 B/s = 8 bit/s.
- 1 Mbps = 1000000 bps ÷ 8 bps per B/s = 125000 B/s
Both units are defined exactly, so the factor is exact. Megabit per Second definition: megabit per second; Byte per Second definition: byte per second.
Worked examples
- A reading of 25 Mbps converts to 3125000 B/s.
25 Mbps × 125000 = 3125000 B/s - A value of 200 Mbps is 25000000 B/s.
200 Mbps × 125000 = 25000000 B/s

Frequently asked questions
How many bytes per second are in 1 megabit per second?
1 Mbps = 125000 B/s.
How do I convert megabits per second to bytes per second?
Multiply the value in Mbps by 125000. For example, 15 Mbps × 125000 = 1875000 B/s.
Is the Mbps to B/s conversion exact?
Yes. Both units are defined exactly, and 1 Mbps is exactly 125000 B/s.
