Kilowatt hours: Kilowatt-hours (kWh) are equal to 1,000 watt-hours. This unit is commonly used for measuring electrical energy consumption, especially in household and industrial contexts. Electric utility companies use kilowatt-hours to measure and bill for energy consumption.
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.
