Convert wavelength units including meters, centimeters, millimeters, micrometers, nanometers, angstroms, inches, feet, yards, miles, and more.
Meters to nanometers:
1 m = 1,000,000,000 nm
Micrometers to nanometers:
1 µm = 1,000 nm
Nanometers to angstroms:
1 nm = 10 Å
Inches to millimeters:
1 in = 25.4 mm
Wavelength conversions are useful for optics, laser wavelengths, LED light, radio frequencies, antenna sizing, sound waves, vibration, spectroscopy, fiber optics, and electromagnetic wave calculations.
Use this converter when comparing metric, U.S. customary, optical, radio, acoustic, and scientific wavelength units.
Your result shows the entered wavelength converted from the starting unit into the selected ending unit. The calculator also shows the conversion rate used so you can verify the calculation.
For engineering, optics, radio, acoustics, and wave calculations, make sure the wavelength unit matches your formula, antenna reference, optical specification, instrument reading, or calculation sheet.
Wavelength is the distance between matching points on a repeating wave, such as crest to crest or compression to compression.
Wavelength is a length measurement, so it can be measured in meters, millimeters, micrometers, nanometers, angstroms, inches, feet, and other length units.
One meter equals 1,000,000,000 nanometers.
One nanometer equals 10 angstroms.
This converter is designed for wavelength magnitude conversions, so it uses non-negative values.
