Convert Megabytes to Gigabits (MB to Gbit)
1 megabyte (MB) = 0.008 gigabits (Gbit). 1 Gbit = 125 MB. Example: 15 MB = 15 × 0.008 = 0.12 Gbit.

How to Convert Megabyte to Gigabit
- 1 MB = 0.008 Gbit
- 1 Gbit = 125 MB
- Example: convert 15 MB to Gbit: 15 MB = 15 × 0.008 Gbit = 0.12 Gbit
Formula
Gbit = MB ÷ 125
Derivation from SI units:
- 1 MB = 10⁶ bytes = 8 × 10⁶ bits (decimal, SI).
- 1 Gbit = 10⁹ bits.
- 1 MB = 8000000 bit ÷ 1000000000 bit per Gbit = 0.008 Gbit
Both units are defined exactly, so the factor is exact. Megabyte definition: megabyte; Gigabit definition: gigabit.
Worked examples
- A reading of 16 MB converts to 0.128 Gbit.
16 MB × 0.008 = 0.128 Gbit - A value of 128 MB is 1.024 Gbit.
128 MB × 0.008 = 1.024 Gbit

Frequently asked questions
How many gigabits are in 1 megabyte?
1 MB = 0.008 Gbit.
How do I convert megabytes to gigabits?
Multiply the value in MB by 0.008, or divide it by 125. For example, 15 MB × 0.008 = 0.12 Gbit.
Is the MB to Gbit conversion exact?
Yes. Both units are defined exactly, and 1 MB is exactly 0.008 Gbit.
