Comparison of Units

The following table is meant as a rough estimation for comparing frequently used units of energy or frequency.

Wavelength Frequency Wave Number Energy Temperature

1 cm 30 GHz 1 cm^-1 1/8 meV 1.5 K

500 nm 600 THz 20000 cm^-1 2.5 eV 30000 K

To obtain more precise information please use the calculator:

Calculate between
Molecular weight input for calculation of magnetic susceptibility:
Only when concerning per cm³ units or SI unitless absolute magnetic susceptibility or wanting such items
kind of sensible, you also have to input a density of the sample (g/cm³):
