Summary
Gigahertz (GHz) and hertz (Hz) are both units of frequency. One gigahertz equals exactly 1,000,000,000 hertz, so converting between them is a simple multiplication by one billion. This tool performs the arithmetic instantly for any value you enter, and also lets you reverse the direction from Hz back to GHz.
How it works
- Enter a frequency value in the gigahertz (GHz) field.
- The converter multiplies the value by 1,000,000,000 to get hertz.
- The result appears immediately with up to 6 significant digits.
- Click the swap button to reverse the direction (Hz → GHz).
- Use the copy button to copy the result to your clipboard.
Use cases
- Express CPU or processor clock speeds as raw hertz values for technical datasheets.
- Convert Wi-Fi band frequencies (2.4 GHz, 5 GHz) into hertz for signal analysis tools.
- Translate oscillator specifications from GHz to Hz for circuit simulations.
- Convert radar or satellite band center frequencies from GHz to Hz.
- Check published GHz frequencies against equipment specs listed in Hz.
