Gigajoules to Electronvolts Converter

Convert gigajoules (GJ) to electronvolts (eV), with the formula, a conversion table and exact factors.

Change the values and press Calculate to work out your own figures.

Enter an amount of energy, choose its unit and the unit you want. The answer is exact until it is shown, and the same value appears in every other unit.

A number, fraction (3/8), mixed number (1 1/2), scientific notation (2.5e6) or a simple sum such as 2*3.
The unit you want the answer in. Swap exchanges the two units.

Show the working
  1. 1 GJ = 6.24150907446e27 eV
  2. 1 × 6.24150907446e27 = 6.24150907446e27 eV

How to convert gigajoules to electronvolts

1 GJ = 6.24150907446 × 10²⁷ eV, so multiply by 6.24150907446 to go from gigajoules to electronvolts. Going the other way, 1 eV = 1.602176634 × 10⁻²⁸ GJ.

eV = GJ × 6.24150907446
GJ = eV × 1.602176634

Worked example:

1 GJ = 6.24150907446e27 eV
5 × 6.24150907446e27 = 3.12075453723e28 eV
