## How the conversion works

The relationship is Gb = B × 8 × 10^-9. Both units measure data, so the conversion is a fixed factor that never changes.

## Common questions

### How many gigabits are in one byte?

One byte equals 8 × 10^-9 gigabits. Gb = B × 8 × 10^-9.

### How do you convert bytes to gigabits?

Use Gb = B × 8 × 10^-9. So 10 B is 8 × 10^-8 Gb.

### How many bytes are in one gigabit?

One gigabit equals 125,000,000 bytes, which is the reverse of the conversion above.
