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.

Foot pounds: Foot-pounds (ft·lbf) are a unit of work or energy in the British Imperial and US customary systems. One foot-pound is the amount of energy expended when a one-pound force is applied over a distance of one foot. This unit is often used in engineering and mechanical contexts to describe torque and work.
