# Gigabits to megabits

**1 gigabit in megabits: 1 Gb = 1,000 Mb**

Mb = Gb × 1,000

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

## Common questions

### How many megabits are in one gigabit?

One gigabit equals 1,000 megabits. Mb = Gb × 1,000.

### How do you convert gigabits to megabits?

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

### How many gigabits are in one megabit?

One megabit equals 0.001 gigabits, which is the reverse of the conversion above.
