Converting from Calorie (cal) to Electronvolt (eV) | Energy

What is Calorie (cal)

A Calorie (cal) is a unit of energy commonly used in chemistry and physics. It represents the amount of thermal energy needed to raise the temperature of one gram of water by one degree Celsius.

What is Electronvolt (eV)

An Electronvolt (eV) is a unit of energy used in physics and electronics. It is the amount of kinetic energy gained by an electron when accelerated through an electric potential difference of one volt.
