## How the conversion works

The relationship is Gb = bit × 1 × 10^-9. Both units measure data, so the conversion is a fixed factor that never changes.

## Common questions

### How many gigabits are in one bit?

One bit equals 1 × 10^-9 gigabits. Gb = bit × 1 × 10^-9.

### How do you convert bits to gigabits?

Use Gb = bit × 1 × 10^-9. So 10 bit is 1 × 10^-8 Gb.

### How many bits are in one gigabit?

One gigabit equals 1,000,000,000 bits, which is the reverse of the conversion above.
