How to Convert Electron-volt to Joule. 1 eV = 1.6021766339999E-19 J. 1 J = 6.241509074461E+18 eV. Example: convert 15 eV to J: 15 eV = 15 × 1.6021766339999E-19 J = 2.4032649509999E-18 J.
When used as a unit of energy, the numerical value of 1 eV in joules (symbol J) is equal to the numerical value of the charge of an electron in coulombs (symbol C). Under the 2019 revision of the SI , this sets 1 eV equal to the exact value 1.602 176 634 × 10 −19 J .
