# Gigahertz to hertz

**1 gigahertz in hertz: 1 GHz = 1,000,000,000 Hz**

Hz = GHz × 1,000,000,000

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

## Gigahertz to hertz table

*Common gigahertz values converted to hertz.*

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

## How the conversion works

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

## Common questions

### How many hertz are in one gigahertz?

One gigahertz equals 1,000,000,000 hertz. Hz = GHz × 1,000,000,000.

### How do you convert gigahertz to hertz?

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

### How many gigahertz are in one hertz?

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