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.

Kilocalories: Kilocalories (kcal), also known as food calories, are equal to 1,000 small calories. This unit is commonly used in the context of food energy, with dietary energy intake and expenditure often measured in kilocalories.
