About Kilowatts
A kilowatt (kW) is 1,000 W - the everyday unit for home, vehicle, and industrial power. Average US home consumption is ~1.2 kW continuous (~10,500 kWh/year). EV motors range from 30 kW (city cars) to 600+ kW (performance models); a Tesla Model S Performance produces 560 kW (751 hp). Industrial gas turbines on commercial aircraft generate 20,000-100,000 kW. Solar installations are sized in kW-peak. Industrial electric motors span from fractional kW to thousands of kW. 1 kW = 1,000 W = 1.341 hp = 3,412.1 BTU/h.
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.
