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.
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.
