# Gigabits to bits

**1 gigabit in bits: 1 Gb = 1,000,000,000 bit**

bit = Gb × 1,000,000,000

To convert gigabits to bits, multiply by 1,000,000,000. 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 × 1,000,000,000. Both units measure data, so the conversion is a fixed factor that never changes.

## Common questions

### How many bits are in one gigabit?

One gigabit equals 1,000,000,000 bits. bit = Gb × 1,000,000,000.

### How do you convert gigabits to bits?

Use bit = Gb × 1,000,000,000. So 10 Gb is 10,000,000,000 bit.

### How many gigabits are in one bit?

One bit equals 1 × 10^-9 gigabits, which is the reverse of the conversion above.
