Electron volts to wavenumbers
Type a value in eV to get it in cm⁻¹ instantly.
806,554.4cm⁻¹
That's 10× as strong as a nitrogen triple bond — nothing on our list beats it. That is about 3,892 times the thermal energy available at room temperature.
What it means
How much energy is that?
Per-particle units such as eV and cm⁻¹ are scaled by Avogadro’s number to become per-mole figures, so the two only match for one mole.
The math
How to convert eV to cm⁻¹
To convert electron volts to wavenumbers, multiply by 8,065.54.
Example: 100 eV × 8,065.54 = 806,554 cm⁻¹.
In the other direction, 1 cm⁻¹ = 0.000123984 eV.
