Convert Metric Horsepower to Terawatts
Convert Metric Horsepower (PS) to Terawatts (TW) instantly and accurately.
Conversion Formula
TW = PS × 7.354987500e-10
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 Terawatts
A terawatt (TW) is 10¹² W. All of human civilisation consumes ~17-18 TW (electricity + heat + transport combined); global electricity generation alone is ~9 TW. Solar irradiance intercepted by Earth is ~174,000 TW; photosynthesis captures ~130 TW. The National Ignition Facility (NIF) fusion laser produces pulses of ~500 TW lasting nanoseconds. High-power laser facilities for nuclear physics and ICF research routinely exceed 1 TW in ultrashort pulse regimes. 1 TW = 10¹² W.
