The SI derived unit for **energy** is the joule.

1 joule is equal to 6.2415064799632E+18 eV, or 0.001 kJ.

Note that rounding errors may occur, so always check the results.

You can do the reverse unit conversion from kJ to eV, or enter any two units below:

In physics, the electron volt (eV) is a unit of energy. By definition, it is equal to the amount of kinetic energy gained by a single unbound electron when it accelerates through an electrostatic potential difference of one volt.

The SI prefix "kilo" represents a factor of
10^{3}, or in exponential notation, 1E3.

So 1 kilojoule = 10^{3} joules.

The definition of a joule is as follows:

The joule (symbol J, also called newton meter, watt second, or coulomb volt) is the SI unit of energy and work. The unit is pronounced to rhyme with "tool", and is named in honor of the physicist James Prescott Joule (1818-1889).
