To convert BTU per hour to foot-pounds per second, multiply the value by the conversion factor:

1 BTU/h = 0.216158 ft·lbf/s

For example: 10 BTU/h = 2.1616 ft·lbf/s

The Conversion Formula

To convert BTU per hour to foot-pounds per second, multiply the value by the conversion factor: 1 BTU/h = 0.216158 ft·lbf/s. For a worked example, suppose you need to convert 25 BTU/h to foot-pounds per second: 25 × 0.216158 = 5.4039 ft·lbf/s. To convert in the opposite direction, divide by 0.216158, or equivalently multiply by 4.6263.

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.

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.

When Would You Convert BTU per hour to foot-pounds per second?

Converting between btu per hour and foot-pounds per second is one of the most common power conversions. You might need this conversion when working with international specifications, following instructions written for a different measurement system, or comparing values across different standards. Having the conversion factor (1 BTU/h = 0.216158 ft·lbf/s) memorized or bookmarked can save time in professional and everyday contexts alike.
