How to convert btus per hour to foot-pounds per second
To convert a measurement in btus per hour to foot-pounds per second, multiply the value by 0.216158128407. The conversion factor comes from the relationship between both units and the watt.
For example, to convert 5 BTU/h to foot-pounds per second: 5 × 0.216158128407 = 1.080791 ft·lb/s.
What is a btu per hour?
A BTU per hour is a unit of power equal to about 0.293 watts, used to rate the heating and cooling capacity of HVAC equipment. Derived from the British thermal unit, BTU/h became the standard rating for air conditioners, furnaces, and heat pumps in the United States, where a '12,000 BTU' unit describes one ton of cooling.
Common uses of btus per hour include: Air conditioner cooling capacity; Furnace and heat-pump ratings; HVAC load calculations; Radiator and boiler output.
What is a foot-pound per second?
A foot-pound per second is an imperial unit of power equal to about 1.356 watts, representing one foot-pound of work performed each second. Rooted in imperial mechanics, the foot-pound per second is the basis from which horsepower was defined — 550 ft·lb/s equals one mechanical horsepower.
Common uses of foot-pounds per second include: Mechanical engineering in imperial units; Deriving horsepower from work rate; Physics work-and-power problems; Legacy machinery specifications.
