Conversion Formula
PS = erg/s × 1.359621617e-10
About Ergs per Second
An erg per second (erg/s) is the CGS unit of power - exactly 10⁻⁷ W. Despite SI adoption, erg/s persists in astrophysics: the Sun's total luminosity is 3.828 × 10³³ erg/s; a peak supernova radiates ~10⁴³ erg/s - more power than the Sun emits over its 10-billion-year lifetime. X-ray binaries, active galactic nuclei, and neutron star accretion rates are catalogued in erg/s across decades of archival literature. 1 erg/s = 10⁻⁷ W.
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.
