Conversion Formula
cal/s = ft⋅lbf/s × 0.3238315535
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.
About Calories per Second
One calorie per second (cal/s) = exactly 4.1868 W. It bridges thermochemistry and power: bomb calorimeters and reaction calorimeters characterise exothermic events by cal/s during the reaction interval. Food science uses cal/s to model heat transfer into food during frying or roasting. Since 1 kcal/s = 4,186.8 W, kilocalories per second appear in high-intensity industrial dryers and continuous-flow reactor heat duties. 1 cal/s = 4.1868 W.
