Megahertz quick reference
| Megahertz | Kilohertz | Gigahertz | Wavelength in meters |
|---|---|---|---|
| 1 MHz | = 1000 kHz | = 0.001 GHz | = 299.792458 λ m |
| 10 MHz | = 10000 kHz | = 0.01 GHz | = 29.9792458 λ m |
| 100 MHz | = 100000 kHz | = 0.1 GHz | = 2.99792458 λ m |
| 1000 MHz | = 1000000 kHz | = 1 GHz | = 0.299792458 λ m |
Where the megahertz fits
The next smaller frequency & wavelength unit is the kilometer of wavelength (λ km). 1 MHz = 0.299792458 λ km, and 1 λ km = 0.299792458 MHz.
The next larger frequency & wavelength unit is the meter of wavelength (λ m). 1 MHz = 299.792458 λ m, and 1 λ m = 299.792458 MHz.
