About foot-pounds per second and BTU per hour
The Conversion Formula
To convert foot-pounds per second to BTU per hour, multiply the value by the conversion factor: 1 ft·lbf/s = 4.6263 BTU/h. For a worked example, suppose you need to convert 25 ft·lbf/s to BTU per hour: 25 × 4.6263 = 115.66 BTU/h. To convert in the opposite direction, divide by 4.6263, or equivalently multiply by 0.216158.
About foot-pounds per second
The foot-pound per second is the base unit of power in the English engineering system. It is defined as the power needed to lift 1 pound 1 foot in 1 second. 550 of these equal 1 horsepower. It is mostly used in engineering textbooks today. foot-pounds per second are commonly used in Mechanical engineering, Physics problems (US), Torque/Power derivations, and other fields.
Lifting a 1lb book 1ft in 1s takes 1 ft-lb/s of power.
About BTU per hour
BTU per hour is the standard unit for HVAC (Heating, Ventilation, and Air Conditioning) in the United States. Confusingly, people often drop the 'per hour' and just say 'This AC is 12,000 BTUs', which technically refers to energy, not power. But in the context of appliances, it always means BTU/h. BTU per hour are commonly used in Air conditioners, Gas grills, Space heaters, and Refrigerators, Furnaces.
A small window AC unit is 5,000 BTU/h.
When Would You Convert foot-pounds per second to BTU per hour?
