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.
Btu: British Thermal Units (BTU) are a measure of heat energy. One BTU is defined as the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit. This unit is commonly used in the power, steam generation, and heating, ventilation, and air conditioning (HVAC) industries.
