Convert Foot-Pounds per Minute to Exawatts
Convert Foot-Pounds per Minute (ft⋅lbf/min) to Exawatts (EW) instantly and accurately.
Conversion Formula
EW = ft⋅lbf/min × 2.259696581e-20
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.
About Exawatts
An exawatt (EW) is 10¹⁸ W. The Sun's total luminosity is 3.828 × 10²⁶ W = 3.828 × 10⁸ EW. Earth intercepts ~0.174 EW of solar power. Gamma-ray burst peak luminosities reach 10⁶-10¹ EW, making them the most powerful transients in the universe. Soft gamma-repeater (magnetar) giant flares briefly reach ~10⁵ EW. Proposed multi-exawatt laser projects (IZEST initiative) aim to compress kilojoules into attosecond pulses for QED vacuum physics. Global human civilisation consumes ~1.8 × 10⁻² EW (18 TW). 1 EW = 10¹⁸ W.
