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 Hour

One BTU per hour (BTU/h) ≈ 0.2931 W - the dominant HVAC capacity unit in the US and Canada. Room air conditioners are universally rated in BTU/h: 12,000 BTU/h = 1 ton of refrigeration = 3,517 W. Home furnaces range from 40,000-150,000 BTU/h. Office building cooling demand is calculated in BTU/h per ft². Engineers convert: BTU/h × 0.2931 = W; or W × 3.412 = BTU/h. 1 BTU/h = 0.29307 W.
