About Petawatts
A petawatt (PW) is 10¹⁵ W. Total solar power intercepted by Earth is ~174 PW. The world's most powerful laser pulses operate at petawatt peak power via chirped pulse amplification (CPA, 2018 Nobel Prize in Physics): China's SULF demonstrated 10 PW in 2019; ELI-NP targets 10 PW. These PW pulses last femtoseconds and create plasma temperatures of billions of kelvin in laboratory targets. Gamma-ray bursts radiate 10²⁴-10²⁷ W at peak - thousands to billions of times the petawatt scale. 1 PW = 10¹⁵ 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.
