Wavelength in nanometers quick reference
| Wavelength in nanometers | Terahertz | Megahertz | Wavelength in meters |
|---|---|---|---|
| 1 λ nm | = 299792.458 THz | = 299792458000 MHz | = 1e-9 λ m |
| 10 λ nm | = 29979.2458 THz | = 29979245800 MHz | = 1e-8 λ m |
| 100 λ nm | = 2997.92458 THz | = 2997924580 MHz | = 1e-7 λ m |
| 1000 λ nm | = 299.792458 THz | = 299792458 MHz | = 0.000001 λ m |
Where the nanometer of wavelength fits
The next smaller frequency & wavelength unit is the micrometer of wavelength (λ µm). 1 λ nm = 0.001 λ µm, and 1 λ µm = 1000 λ nm.
