Wavelength in millimeters quick reference
| Wavelength in millimeters | Megahertz | Wavelength in meters | Hertz |
|---|---|---|---|
| 1 λ mm | = 299792.458 MHz | = 0.001 λ m | = 299792458000 Hz |
| 10 λ mm | = 29979.2458 MHz | = 0.01 λ m | = 29979245800 Hz |
| 100 λ mm | = 2997.92458 MHz | = 0.1 λ m | = 2997924580 Hz |
| 1000 λ mm | = 299.792458 MHz | = 1 λ m | = 299792458 Hz |
Where the millimeter of wavelength fits
The next smaller frequency & wavelength unit is the centimeter of wavelength (λ cm). 1 λ mm = 0.1 λ cm, and 1 λ cm = 10 λ mm.
The next larger frequency & wavelength unit is the terahertz (THz). 1 λ mm = 0.299792458 THz, and 1 THz = 0.299792458 λ mm.
