How to Convert Joule to Electronvolt
To convert Joule (J) to Electronvolt (eV), use the formula: 1 J = 6.242197e+18 eV.
For example, to convert 5 J to eV: 5 J = 3.121099e+19 eV. Similarly, 10 J = 6.242197e+19 eV, 25 J = 1.560549e+20 eV, and 100 J = 6.242197e+20 eV.
To convert in the other direction, 1 eV = 1.602000e-19 J. Simply enter your value in either field above for instant bi-directional conversion.
What is a Joule?
A joule (J) is the SI unit of energy — the work done by a force of one newton over one meter. Joules are used in physics and engineering for energy calculations.
What is a Electronvolt?
An electronvolt (eV) is the energy gained by an electron moving through 1 volt of potential. Electronvolts are used in particle physics and quantum mechanics.
