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.

Therms: Therms are a unit of heat energy equal to 100,000 BTUs. This unit is commonly used to measure natural gas consumption. In the energy industry, therms are used to describe the energy content of natural gas and to bill for its consumption.
