Gigajoules to Kiloelectronvolts Converter

Convert gigajoules (GJ) to kiloelectronvolts (keV), 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 = 6.24150907446e24 keV
  2. 1 × 6.24150907446e24 = 6.24150907446e24 keV

How to convert gigajoules to kiloelectronvolts

1 GJ = 6.24150907446 × 10²⁴ keV, so multiply by 6.24150907446 to go from gigajoules to kiloelectronvolts. Going the other way, 1 keV = 1.602176634 × 10⁻²⁵ GJ.

keV = GJ × 6.24150907446
GJ = keV × 1.602176634

Worked example:

1 GJ = 6.24150907446e24 keV
5 × 6.24150907446e24 = 3.12075453723e25 keV
