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.
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.
