Metric Horsepower (PS)
The metric horsepower (PS, CV, ch) is 75 kilogram-force metres per second, exactly 735.49875 W, about 1.4 % less than a mechanical horsepower.
Symbol: PS
Quantity: power (energy per unit time)
SI relation: 1 PS = 735.49875 W (exact)
Derivation: 1 PS = 75 kgf·m/s = 735.49875 W (exact)
Exact: yes, by definition
Typical uses
- European and Japanese car specifications (PS, CV)
- Older European motor ratings
