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. [1]
The conversion between Joule (J) and Electronvolt (eV) can be performed using the following formulas: 1( J ) = 6.25 × 10 18 ( e V ) 1( e V ) = 1.6 × 10 −19 ( J )
