Convert Megabits to Megabytes (Mbit to MB)
1 megabit (Mbit) = 0.125 megabytes (MB). 1 MB = 8 Mbit. Example: 8 Mbit = 8 × 0.125 = 1 MB.

How to Convert Megabit to Megabyte
- 1 Mbit = 0.125 MB
- 1 MB = 8 Mbit
- Example: convert 8 Mbit to MB: 8 Mbit = 8 × 0.125 MB = 1 MB
Formula
MB = Mbit ÷ 8
Derivation from SI units:
- 1 Mbit = 10⁶ bits.
- 1 MB = 10⁶ bytes = 8 × 10⁶ bits (decimal, SI).
- 1 Mbit = 1000000 bit ÷ 8000000 bit per MB = 0.125 MB
Both units are defined exactly, so the factor is exact. Megabit definition: megabit; Megabyte definition: megabyte.
Worked examples
- 8 Mbit is 1 MB.
8 Mbit × 0.125 = 1 MB - A 100 Mbit burst of data is 12.5 MB.
100 Mbit × 0.125 = 12.5 MB

Frequently asked questions
How many megabits are in a megabyte?
Eight, since a byte is 8 bits: 1 Mb = 0.125 MB.
How many megabytes are in 1 megabit?
1 Mbit = 0.125 MB.
How do I convert megabits to megabytes?
Multiply the value in Mbit by 0.125, or divide it by 8. For example, 8 Mbit × 0.125 = 1 MB.
Is the Mbit to MB conversion exact?
Yes. Both units are defined exactly, and 1 Mbit is exactly 0.125 MB.
