How to Convert Electronvolts to Gigajoules

To convert a measurement in electronvolts to a measurement in gigajoules, multiply the energy by the following conversion ratio: 1.6022E-28 gigajoules/electronvolt.

Since one electronvolt is equal to 1.6022E-28 gigajoules, you can use this simple formula to convert:

gigajoules = electronvolts × 1.6022E-28

The energy in gigajoules is equal to the energy in electronvolts multiplied by 1.6022E-28.

For example, here's how to convert 5.0E+27 electronvolts to gigajoules using the formula above.
gigajoules = (5.0E+27 eV × 1.6022E-28) = 0.801088 GJ

Electronvolts and gigajoules are both units used to measure energy. Keep reading to learn more about each unit of measure.

What Is an Electronvolt?

An electronvolt is the amount of energy required to accelerate an electron through a difference in electric potential of one volt in vacuum. One electronvolt is equal to the charge of 1.602176634 × 10−19 C, and is equal to the energy of 1.602176634 × 10−19 Joules.[1]

Electronvolts can be abbreviated as eV; for example, 1 electronvolt can be written as 1 eV.

Energy in electronvolts can be expressed using the following formula: E = qV

The energy E in electronvolts is equal to the electric charge q in elementary charge times the potential difference V in volts.

What Is a Gigajoule?

One gigajoule is equal to 1,000,000,000 joules, which is the energy equal to the force on an object of one newton at a distance of one meter.

The gigajoule is a multiple of the joule, which is the SI derived unit for energy. In the metric system, "giga" is the prefix for billions, or 109. Gigajoules can be abbreviated as GJ; for example, 1 gigajoule can be written as 1 GJ.
