To convert a measurement in kilojoules to a measurement in electronvolts, multiply the energy by the following conversion ratio: 6.2415E+21 electronvolts/kilojoule.

Since one kilojoule is equal to 6.2415E+21 electronvolts, you can use this simple formula to convert:

electronvolts = kilojoules × 6.2415E+21

The energy in electronvolts is equal to the energy in kilojoules multiplied by 6.2415E+21.

For example, here's how to convert 5 kilojoules to electronvolts using the formula above.
electronvolts = (5 kJ × 6.2415E+21) = 3.1208E+22 eV

How Many Electronvolts Are in a Kilojoule?

There are 6.2415E+21 electronvolts in a kilojoule, which is why we use this value in the formula above.

1 kJ = 6.2415E+21 eV

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

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.

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.
