About Watts
The watt (W) is the SI unit of power - 1 J/s - named after James Watt (1736-1819). Familiar power levels: smartphone charging 5-65 W; laptop 15-100 W; microwave 700-1,200 W; electric kettle 2,000-3,000 W; human resting metabolism ~80 W; peak sprint ~2,000 W. The now-obsolete 100 W incandescent bulb is replaced by a 10-15 W LED producing the same light. In AC circuits, reactive power uses the var and apparent power the VA, both derived from watts. 1 W = 1 J/s = 1 kg·m²/s³.
About Foot-Pounds per Minute
One foot-pound per minute (ft·lbf/min) ≈ 0.02260 W. Its historical importance is large: James Watt rated mill horses at ~33,000 ft·lbf/min sustained output and defined 1 mechanical horsepower as exactly 33,000 ft·lbf/min (= 550 ft·lbf/s). The unit is still used for machine-tool power, hydraulic pump output, and low-speed actuator performance in US customary calculations: torque (ft·lbf) × RPM = power in ft·lbf/min. 1 hp = 33,000 ft·lbf/min.
