# Megahertz to gigahertz

**1 megahertz in gigahertz: 1 MHz = 0.001 GHz**

GHz = MHz × 0.001

To convert megahertz to gigahertz, multiply by 0.001. The table below gives the values people look up most often, and the converter works for any number.

## Megahertz to gigahertz table

*Common megahertz values converted to gigahertz.*

| Megahertz | Gigahertz |
| --- | --- |
| 1 MHz | 0.001 |
| 2 MHz | 0.002 |
| 3 MHz | 0.003 |
| 4 MHz | 0.004 |
| 5 MHz | 0.005 |
| 10 MHz | 0.01 |
| 15 MHz | 0.015 |
| 20 MHz | 0.02 |
| 25 MHz | 0.025 |
| 30 MHz | 0.03 |
| 40 MHz | 0.04 |
| 50 MHz | 0.05 |
| 75 MHz | 0.075 |
| 100 MHz | 0.1 |
| 250 MHz | 0.25 |
| 500 MHz | 0.5 |
| 1,000 MHz | 1 |

## How the conversion works

The relationship is GHz = MHz × 0.001. Both units measure frequency, so the conversion is a fixed factor that never changes.

## Common questions

### How many gigahertz are in one megahertz?

One megahertz equals 0.001 gigahertz. GHz = MHz × 0.001.

### How do you convert megahertz to gigahertz?

Use GHz = MHz × 0.001. So 10 MHz is 0.01 GHz.

### How many megahertz are in one gigahertz?

One gigahertz equals 1,000 megahertz, which is the reverse of the conversion above.
