Wavenumbers to kilojoules per mole
Type a value in cm⁻¹ to get it in kJ/mol instantly.
1.196kJ/mol
Nothing on our list is smaller: room-temperature thermal energy is 2.1× higher. That is about 0.4826 times the thermal energy available at room temperature.
Convert the other way: kJ/mol to cm⁻¹
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 cm⁻¹ to kJ/mol
To convert wavenumbers to kilojoules per mole, multiply by 0.0119627.
Example: 100 cm⁻¹ × 0.0119627 = 1.19627 kJ/mol.
In the other direction, 1 kJ/mol = 83.5935 cm⁻¹.
