## How the conversion works

The relationship is GB = bit × 1.25 × 10^-10. Both units measure data, so the conversion is a fixed factor that never changes.

## Common questions

### How many gigabytes are in one bit?

One bit equals 1.25 × 10^-10 gigabytes. GB = bit × 1.25 × 10^-10.

### How do you convert bits to gigabytes?

Use GB = bit × 1.25 × 10^-10. So 10 bit is 1.25 × 10^-9 GB.

### How many bits are in one gigabyte?

One gigabyte equals 8,000,000,000 bits, which is the reverse of the conversion above.
