Understanding Electronvolts and Kilocalories

What is an Electronvolt (eV)?

An electronvolt is a unit of energy equal to the amount of kinetic energy gained by a single electron accelerating through an electric potential difference of one volt in a vacuum. It's commonly used in atomic physics and particle physics.

What is a Kilocalorie (kcal)?

A kilocalorie is a unit of energy equal to 1,000 calories. It represents the amount of energy needed to raise the temperature of one kilogram of water by one degree Celsius at atmospheric pressure. This unit is widely used in nutrition and food science.
