An electron-volt (eV) is a unit of energy equal to approximately 1.602 x 10^-19 joules. It represents the amount of kinetic energy gained or lost by a single electron as it moves across an electric potential difference of one volt. Electron-volts are commonly used in atomic, molecular, and particle physics to quantify the small amounts of energy typically involved in these processes.
Definition of KilojouleA kilojoule (kJ) is a unit of energy in the International System of Units (SI), equivalent to 1,000 joules. It is a metric measure of energy or work done and is widely used in various scientific contexts, including physics, chemistry, and nutrition. One kilojoule reflects the amount of energy required to exert a force of one thousand newtons over a distance of one meter.

1 kJ = 6.242 x 10^18 eV
Example 1:
convert 5 eV to kJ:
5 eV = 5 x 1.602 x 10^-22 kJ = 8.01 x 10^-22 kJ
Example 2:
convert 10,000 eV to kJ:
10,000 eV = 10,000 x 1.602 x 10^-22 kJ = 1.602 x 10^-18 kJ
The concept of converting electron-volts to kilojoules emerged from the need to translate atomic-scale energy units to larger-scale energy measurements. This conversion became valuable in scientific fields, especially in physics and chemistry, where understanding the energy involved in reactions at the electron level is crucial.
