How the conversion works

The relationship is kJ = eV × 1.602176634 × 10^-22. Both units measure energy, so the conversion is a fixed factor that never changes.

Common questions

How many kilojoules are in one electronvolt?
One electronvolt equals 1.602 × 10^-22 kilojoules. kJ = eV × 1.602176634 × 10^-22.
How do you convert electronvolts to kilojoules?
Use kJ = eV × 1.602176634 × 10^-22. So 10 eV is 1.602 × 10^-21 kJ.
How many electronvolts are in one kilojoule?
One kilojoule equals 6.2415091 × 10^21 electronvolts, which is the reverse of the conversion above.
