Wavelength in micrometers to Terahertz Converter
Use this page to convert wavelength in micrometers values into terahertz, with background details, formulas, a worked example, and a quick conversion table.
Conversion formula
This conversion uses an offset formula rather than a single multiplier because the temperature scales start from different zero points.
um wavelength to THz: Apply the scale formula and then add or remove the required offset.
Example: 1000000000 um wavelength = 0.000000299792458 THz
Wavelength in micrometers
Frequency in hertz equals the speed of light divided by wavelength in meters, after converting micrometers to meters.
History: Micrometer wavelengths are common in infrared optics.
Current use: Used for infrared light, lasers, spectroscopy, and optical materials.
Also written as um wavelength, micrometer wavelength, micrometre wavelength, wavelength micrometers.
Terahertz
One terahertz is equal to one trillion hertz (1000000000000 hertz).
History: Terahertz units are used between microwave and infrared frequency ranges.
Current use: Used in spectroscopy, imaging, communications, and optical-frequency references.
Also written as THz, terahertz.
