How to Convert Electronvolts to Kilojoules

To convert a measurement in electronvolts to a measurement in kilojoules, multiply the energy by the following conversion ratio: 1.6022E-22 kilojoules/electronvolt.

Since one electronvolt is equal to 1.6022E-22 kilojoules, you can use this simple formula to convert:

kilojoules = electronvolts × 1.6022E-22

The energy in kilojoules is equal to the energy in electronvolts multiplied by 1.6022E-22.

For example, here's how to convert 5.0E+21 electronvolts to kilojoules using the formula above.
kilojoules = (5.0E+21 eV × 1.6022E-22) = 0.801088 kJ

Electronvolts and kilojoules 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 Kilojoule?

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

The kilojoule is a multiple of the joule, which is the SI derived unit for energy. In the metric system, "kilo" is the prefix for thousands, or 103. Kilojoules can be abbreviated as kJ; for example, 1 kilojoule can be written as 1 kJ.
