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.

Kilojoules: Kilojoules (kJ) are equal to 1,000 joules. This unit is often used in fields such as chemistry and nutrition to quantify energy. For example, food energy is commonly expressed in kilojoules per serving or per 100 grams.
