How to Convert Gigajoules to Electronvolts

To convert a measurement in gigajoules to a measurement in electronvolts, multiply the energy by the following conversion ratio: 6.2415E+27 electronvolts/gigajoule.

Since one gigajoule is equal to 6.2415E+27 electronvolts, you can use this simple formula to convert:

electronvolts = gigajoules × 6.2415E+27

The energy in electronvolts is equal to the energy in gigajoules multiplied by 6.2415E+27.

For example, here's how to convert 5 gigajoules to electronvolts using the formula above.
electronvolts = (5 GJ × 6.2415E+27) = 3.1208E+28 eV

How Many Electronvolts Are in a Gigajoule?

There are 6.2415E+27 electronvolts in a gigajoule, which is why we use this value in the formula above.

1 GJ = 6.2415E+27 eV

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

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.

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.
