Gigahertz to Hertz
1 GHz = 1000000000 Hz
How to convert gigahertz to hertz
Enter the value in gigahertz (GHz) above and the equivalent in hertz (Hz) updates as you type. This conversion comes up when audio work: musical pitch and equipment specs (Hz, kHz).
- Concert pitch A above middle C: 440 Hz → that is 0 GHz in gigahertz.
- European mains power: 50 Hz, US: 60 Hz → that is 0 GHz in gigahertz.
Typical situations: radio: broadcast bands in kHz/MHz; electronics: mains frequency (50 Hz vs 60 Hz countries) and CPU clocks (GHz).
You can also convert in the other direction: Hertz to Gigahertz
Gigahertz to Hertz conversion table
| Gigahertz (GHz) | Hertz (Hz) |
|---|---|
| 1 | 1000000000 |
| 2 | 2000000000 |
| 5 | 5000000000 |
| 10 | 10000000000 |
| 25 | 25000000000 |
| 50 | 50000000000 |
| 100 | 100000000000 |
Watch out for
- kHz vs MHz in radio: a factor of 1,000; FM is around 100 MHz, AM around 1 MHz
- Mains frequency does not affect voltage, which is why 50/60 Hz devices are often but not always interchangeable
