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 BTU per Second

One BTU per second (BTU/s) ≈ 1,055 W - close to 1 kW but slightly larger. Used when heat rates are so high that per-hour or per-minute numbers become unwieldy. In fire protection engineering, large house fires peak at 500-2,000 BTU/s; industrial fires at millions of BTU/s. Blast characterisation for petrochemical safety and large industrial heat exchangers with duties of millions of BTU/h are conveniently expressed in BTU/s. Since 1 BTU/s ≈ 1.055 kW, conversion to SI is straightforward. 1 BTU/s = 1,055.056 W.
