# Gigahertz to megahertz

**1 gigahertz in megahertz: 1 GHz = 1,000 MHz**

MHz = GHz × 1,000

To convert gigahertz to megahertz, multiply by 1,000. The table below gives the values people look up most often, and the converter works for any number.

## Gigahertz to megahertz table

*Common gigahertz values converted to megahertz.*

| Gigahertz | Megahertz |
| --- | --- |
| 1 GHz | 1,000 |
| 2 GHz | 2,000 |
| 3 GHz | 3,000 |
| 4 GHz | 4,000 |
| 5 GHz | 5,000 |
| 10 GHz | 10,000 |
| 15 GHz | 15,000 |
| 20 GHz | 20,000 |
| 25 GHz | 25,000 |
| 30 GHz | 30,000 |
| 40 GHz | 40,000 |
| 50 GHz | 50,000 |
| 75 GHz | 75,000 |
| 100 GHz | 100,000 |
| 250 GHz | 250,000 |
| 500 GHz | 500,000 |
| 1,000 GHz | 1,000,000 |

## How the conversion works

The relationship is MHz = GHz × 1,000. Both units measure frequency, so the conversion is a fixed factor that never changes.

## Common questions

### How many megahertz are in one gigahertz?

One gigahertz equals 1,000 megahertz. MHz = GHz × 1,000.

### How do you convert gigahertz to megahertz?

Use MHz = GHz × 1,000. So 10 GHz is 10,000 MHz.

### How many gigahertz are in one megahertz?

One megahertz equals 0.001 gigahertz, which is the reverse of the conversion above.
