Convert Calories per Hour to Foot-Pounds per Second
Convert Calories per Hour (cal/h) to Foot-Pounds per Second (ft⋅lbf/s) instantly and accurately.
Conversion Formula
ft⋅lbf/s = cal/h × 0.0008577847796
About Calories per Hour
One calorie per hour (cal/h) equals exactly 0.001163 W - the rate of transferring one thermochemical calorie (4.1868 J) per hour. A resting adult generates ~70-80 W ≈ 60,000-70,000 cal/h of heat. The unit appears in European and Asian HVAC standards for small-appliance heat loads and in laboratory calorimetry reporting metabolic activity of small organisms. Calorimetric enzyme assays also express catalytic heat in cal/h per unit enzyme. 1 cal/h = 0.001163 W.
About Foot-Pounds per Second
One foot-pound per second (ft·lbf/s) ≈ 1.3558 W - the natural power unit in the foot-pound-second (FPS) system. Since 1 mechanical horsepower = exactly 550 ft·lbf/s, the conversion 1 ft·lbf/s = 1/550 hp is exact. Used in FPS structural and fluid dynamics: beam deflection power, pump and turbine output, and ballistic energy-transfer calculations. 19th-century American industry rated waterwheel output in ft·lbf/s before horsepower standardisation. 1 ft·lbf/s = 1.35582 W.
