BTU per hour (BTU/h)
Definition
BTU per hour (BTU/h) is an imperial unit of power equal to approximately 0.293 watts. It measures the rate of thermal energy transfer.
History
The British Thermal Unit (BTU) was established in the 19th century to quantify heat energy. BTU/h emerged as the standard for heating and cooling system ratings, particularly in North America.
Current use
BTU/h is the standard unit for rating heating, ventilation, and air conditioning (HVAC) systems in the United States and Canada. Furnace output, air conditioner capacity, and water heater ratings are specified in BTU/h.
Foot-pounds per second (ft⋅lb/s)
Definition
Foot-pounds per second (ft·lb/s) is an imperial unit of power equal to approximately 1.356 watts. It measures the rate of mechanical work in the foot-pound-second system.
History
Foot-pounds per second is rooted in the British engineering system. James Watt originally defined horsepower as 550 ft·lb/s, establishing the direct relationship between these two power units.
Current use
Foot-pounds per second appears in mechanical engineering calculations, particularly in the United States. It is used in torque-power conversions, machinery specifications, and physics education in imperial-unit contexts.
