About Poncelet
The poncelet is a rare historical unit equal to 100 kgf·m/s = exactly 980.665 W. Proposed by French engineer Jean-Victor Poncelet (1788-1867) as a metric alternative to the horsepower for French engineering practice - the power to lift 100 kg at 1 m/s against gravity. Used in 19th-century French industrial and military engineering (waterwheels, steam engines, horse-operated machinery) before the watt replaced it. At 980.665 W, it sits between the metric horsepower (735.5 W) and the kilowatt (1,000 W). 1 poncelet = 980.665 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.
