Gigahertz quick reference
| Gigahertz | Megahertz | Wavelength in centimeters | Wavelength in meters |
|---|---|---|---|
| 1 GHz | = 1000 MHz | = 29.9792458 λ cm | = 0.299792458 λ m |
| 10 GHz | = 10000 MHz | = 2.99792458 λ cm | = 0.0299792458 λ m |
| 100 GHz | = 100000 MHz | = 0.299792458 λ cm | = 0.00299792458 λ m |
| 1000 GHz | = 1000000 MHz | = 0.0299792458 λ cm | = 0.000299792458 λ m |
Where the gigahertz fits
The next smaller frequency & wavelength unit is the meter of wavelength (λ m). 1 GHz = 0.299792458 λ m, and 1 λ m = 0.299792458 GHz.
The next larger frequency & wavelength unit is the centimeter of wavelength (λ cm). 1 GHz = 29.9792458 λ cm, and 1 λ cm = 29.9792458 GHz.
