Frequently asked questions

How do I convert electronvolts to joules?

To convert electronvolts to joules, multiply the value by 1.602176634 × 10⁻¹⁹: J = eV × 1.602176634 × 10⁻¹⁹. For example 100 eV = 1.602176634 × 10⁻¹⁷ J.

What is 1 eV in joules?

1 eV = 1.602176634 × 10⁻¹⁹ J. The other way round, 1 J = 6.241509074 × 10¹⁸ eV.

How exact is the result?

The converter uses the official definitions of both units and shows up to 10 significant digits; choose 0–6 decimals to round. Both units are defined exactly in terms of each other, so the factor itself is exact.

Can I convert other units of energy here?

Yes – choose any of the 12 units of energy in the From and To lists, or switch to another measurement at the top.
