How to Convert Kilojoules to Electronvolts

To convert a kilojoule measurement to a electronvolt measurement, multiply the energy by the conversion ratio. One kilojoule is equal to 6.2415E+21 electronvolts, so use this simple formula to convert:

electronvolts = kilojoules × 6.2415E+21

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

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

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

Kilojoules

One kilojoule is equal to 1,000 joules, which are 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 103. Kilojoules can be abbreviated as kJ, for example 1 kilojoule can be written as 1 kJ.

Electronvolts

The electronvolt is a unit of energy used in physics, most commonly in electrostatic particle accelerator sciences.

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.
