How to Convert Megabyte to Megabit
- 1 MB = 8 Mbit
- 1 Mbit = 0.125 MB
- Example: convert 1 MB to Mbit: 1 MB = 1 × 8 Mbit = 8 Mbit
Formula
Mbit = MB × 8
Derivation from SI units:
- 1 MB = 10⁶ bytes = 8 × 10⁶ bits (decimal, SI).
- 1 Mbit = 10⁶ bits.
- 1 MB = 8000000 bit ÷ 1000000 bit per Mbit = 8 Mbit
Both units are defined exactly, so the factor is exact. Megabyte definition: megabyte; Megabit definition: megabit.
Worked examples
- 1 MB is 8 Mbit.
1 MB × 8 = 8 Mbit - A 25 MB file is 200 Mbit to send.
25 MB × 8 = 200 Mbit

Frequently asked questions
How long does a 25 MB file take on a 10 Mbps link?
25 MB = 200 Mb, and 200 ÷ 10 = 20 seconds, plus a little protocol overhead.
How many megabits are in 1 megabyte?
1 MB = 8 Mbit.
How do I convert megabytes to megabits?
Multiply the value in MB by 8. For example, 1 MB × 8 = 8 Mbit.
Is the MB to Mbit conversion exact?
Yes. Both units are defined exactly, and 1 MB is exactly 8 Mbit.
