## How the conversion works

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

## Common questions

### How many gigabytes are in one byte?

One byte equals 1 × 10^-9 gigabytes. GB = B × 1 × 10^-9.

### How do you convert bytes to gigabytes?

Use GB = B × 1 × 10^-9. So 10 B is 1 × 10^-8 GB.

### How many bytes are in one gigabyte?

One gigabyte equals 1,000,000,000 bytes, which is the reverse of the conversion above.
