Nanometers to micrometers
Type a value in nm to get it in µm instantly.
0.55µm
That's about the same as green light. That is visible light, carrying 2.254 eV per photon.
What it means
What color is that?
Wavelengths are for a vacuum. In glass or water light slows down and the wavelength shortens, while the frequency stays put.
The math
How to convert nm to µm
To convert nanometers to micrometers, multiply by 0.001.
Example: 550 nm × 0.001 = 0.55 µm.
In the other direction, 1 µm = 1,000 nm.
