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.

Watt hours: Watt-hours (Wh) are a unit of energy equivalent to one watt of power used for one hour. This unit is commonly used to measure electrical energy consumption. For example, household electrical energy usage is often measured in kilowatt-hours (kWh), where 1 kWh equals 1,000 Wh.
