About Units

Electronvolts: Electronvolts (eV) are a unit of energy commonly used in the field of particle physics. One electronvolt is defined as the amount of kinetic energy gained or lost by an electron when it is accelerated through an electric potential difference of one volt. This unit is useful for expressing energy at the atomic and subatomic scales.

Megajoules: Megajoules (MJ) are equal to 1,000,000 joules. This unit is commonly used to describe large quantities of energy, such as the energy content of fuels, electrical energy, and the energy output of engines.
