How to convert Joule to Electronvolt

Conversion factor and calculation steps from Joule (J) to Electronvolt (eV).

Conversion logic

Each unit is defined via the base unit (joule (J)). The value is first converted to the base unit, then to the selected unit.

1 eV = 1.60217663e-19 J

1 J ÷ 1.60217663e-19 = 6.24150907e18 eV
