How to Convert Kiloelectronvolts to Joules

To convert a kiloelectronvolt measurement to a joule measurement, multiply the energy by the conversion ratio. One kiloelectronvolt is equal to 1.6022E-16 joules, so use this simple formula to convert:

joules = kiloelectronvolts × 1.6022E-16

The energy in joules is equal to the kiloelectronvolts multiplied by 1.6022E-16.

For example, here's how to convert 5 kiloelectronvolts to joules using the formula above.
5 keV = (5 × 1.6022E-16) = 8.0109E-16 J

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


Kiloelectronvolts can be abbreviated as keV, for example 1 kiloelectronvolt can be written as 1 keV.


The joule is the energy equal to the force on an object of one newton at a distance of one meter. One joule is equal to the heat energy dissipated by the current of one ampere through one ohm of resistance for one second.

One joule is also equal to the energy needed to move an electric charge of one coulomb through a potential difference of one volt. In addition, one joule is also equal to the one watt-second.

The joule is the SI derived unit for energy in the metric system. Joules can be abbreviated as J, for example 1 joule can be written as 1 J.
