# Gigabits to bytes

**1 gigabit in bytes: 1 Gb = 125,000,000 B**

B = Gb × 125,000,000

To convert gigabits to bytes, multiply by 125,000,000. 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 B = Gb × 125,000,000. Both units measure data, so the conversion is a fixed factor that never changes.

## Common questions

### How many bytes are in one gigabit?

One gigabit equals 125,000,000 bytes. B = Gb × 125,000,000.

### How do you convert gigabits to bytes?

Use B = Gb × 125,000,000. So 10 Gb is 1,250,000,000 B.

### How many gigabits are in one byte?

One byte equals 8 × 10^-9 gigabits, which is the reverse of the conversion above.
