Gigahertz to hertz
Type a value in GHz to get it in Hz instantly.
1×10¹¹Hz
That's 29× as fast as a laptop processor — nothing on our list beats it. As a radio wave, one wave would be 0.002998 m long.
What it means
What does that look like?
The wavelength shown is for sound in air at 20 °C (343 m/s). Radio waves travel at the speed of light, so their wavelengths are far longer.
The math
How to convert GHz to Hz
To convert gigahertz to hertz, multiply by 1×10⁹.
Example: 100 GHz × 1×10⁹ = 1×10¹¹ Hz.
In the other direction, 1 Hz = 1×10⁻⁹ GHz.
