Summary
Hertz (Hz) and gigahertz (GHz) are both units of frequency. One gigahertz equals exactly 1,000,000,000 hertz, so converting between them is a simple division or multiplication by one billion. This tool performs the arithmetic instantly for any value you enter, and also lets you reverse the direction from GHz back to Hz.
How it works
- Enter a frequency value in the hertz (Hz) field.
- The converter divides the value by 1,000,000,000 to get gigahertz.
- The result appears immediately with up to 6 significant digits.
- Click the swap button to reverse the direction (GHz → Hz).
- Use the copy button to copy the result to your clipboard.
Use cases
- Convert CPU or processor clock speeds from Hz to GHz for spec comparisons.
- Express Wi-Fi and 5G signal frequencies (2.4 GHz, 5 GHz, 60 GHz) starting from raw Hz values.
- Convert oscillator frequencies from datasheets listed in Hz to GHz.
- Check radar and satellite band frequencies when working with RF systems.
- Translate scientific instrument sampling rates from Hz to GHz for publication.
