Convert Megabits to Gigabytes (Mbit to GB)
1 megabit (Mbit) = 0.000125 gigabytes (GB). 1 GB = 8000 Mbit. Example: 15 Mbit = 15 × 0.000125 = 0.001875 GB.

How to Convert Megabit to Gigabyte
- 1 Mbit = 0.000125 GB
- 1 GB = 8000 Mbit
- Example: convert 15 Mbit to GB: 15 Mbit = 15 × 0.000125 GB = 0.001875 GB
Formula
GB = Mbit ÷ 8000
Derivation from SI units:
- 1 Mbit = 10⁶ bits.
- 1 GB = 10⁹ bytes = 8 × 10⁹ bits (decimal, SI).
- 1 Mbit = 1000000 bit ÷ 8000000000 bit per GB = 0.000125 GB
Both units are defined exactly, so the factor is exact. Megabit definition: megabit; Gigabyte definition: gigabyte.
Worked examples
- A reading of 16 Mbit converts to 0.002 GB.
16 Mbit × 0.000125 = 0.002 GB - A value of 128 Mbit is 0.016 GB.
128 Mbit × 0.000125 = 0.016 GB
