# Gigabytes to bits

**1 gigabyte in bits: 1 GB = 8,000,000,000 bit**

bit = GB × 8,000,000,000

To convert gigabytes to bits, multiply by 8,000,000,000. The table below gives the values people look up most often, and the converter works for any number.

## How the conversion works

The relationship is bit = GB × 8,000,000,000. Both units measure data, so the conversion is a fixed factor that never changes.

## Common questions

### How many bits are in one gigabyte?

One gigabyte equals 8,000,000,000 bits. bit = GB × 8,000,000,000.

### How do you convert gigabytes to bits?

Use bit = GB × 8,000,000,000. So 10 GB is 80,000,000,000 bit.

### How many gigabytes are in one bit?

One bit equals 1.25 × 10^-10 gigabytes, which is the reverse of the conversion above.
