Convert Metric Horsepower to Exawatts
Convert Metric Horsepower (PS) to Exawatts (EW) instantly and accurately.
Conversion Formula
EW = PS × 7.354987500e-16
About Metric Horsepower
The metric horsepower (PS/CV/pk) equals exactly 75 kgf·m/s = 735.49875 W - the European equivalent of mechanical horsepower, defined as lifting 75 kg by 1 m/s. It was the DIN 66036 standard for European automotive ratings until the EU mandated kW. A 100 PS car produces 73.55 kW; 200 PS = 147.1 kW. The ~1.4% difference from mechanical hp (745.7 W) means a 100 PS car rates as 98.6 mechanical hp. German car advertising still shows PS parenthetically alongside kW. 1 PS = 735.49875 W.
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.
