About This Light Wavelength Converter
Convert wavelength values between nanometers, micrometers, angstroms, metric length units, and imperial length units. The calculator uses nanometers as the base scale, which fits visible light, ultraviolet, infrared, spectroscopy, and optics work.
How to use it
Enter a wavelength, choose the input unit, and select the output unit. Swap reverses the selected units, while Reset returns to nanometers to micrometers.
Units covered
Supported units include nm, µm, Å, mm, cm, m, inch, foot, yard, and mile. Reference checks: 1 nm equals 10 Å, and 1000 nm equals 1 µm.
