Common examples:
Metric horsepower — abbreviated as PS (from German: Pferdestärke, meaning "horse strength") — was defined as the power needed to lift 75 kilograms by 1 meter in 1 second. In SI units: 75 kgf × 1 m/s = 75 × 9.80665 N·m/s = 735.49875 watts (rounded to 735.499 W). It is the standard for car engines in Europe, Japan, India, and most of Asia. Brands like BMW, Mercedes, Porsche, Audi, Toyota, and Honda always rate engines in PS.
The watt (W) is the SI base unit of power — named after Scottish inventor James Watt. It represents one joule of energy transferred per second. Every electrical device is rated in watts. Interestingly, both the watt (W) and metric horsepower (PS) exist to measure the same thing — power — but PS is used specifically for engines while watts are used universally for all power measurements.
The metric horsepower was defined based on a simple physical experiment:
This makes PS a clean metric definition — unlike mechanical hp (745.7 W) which comes from an imperial foot-pound calculation.

Multiply PS by 735.499. Formula: W = PS × 735.499. Example: 150 PS × 735.499 = 110,324.85 W = 110.32 kW.
1 PS = 735.499 watts. This is the exact metric definition — 1 PS = 75 kgf·m/s = 75 × 9.80665 = 735.49875 W.
100 PS = 73,549.9 watts = 73.55 kW. Formula: 100 × 735.499 = 73,549.9 W. This is a typical small European car engine power in watts.
1 PS = 735.499 W while 1 mechanical hp = 745.7 W. The difference is 10.201 W per unit — about 1.4%. So 100 PS car = 73,549.9 W while 100 hp car = 74,570 W.
150 PS = 110,324.85 watts = 110.32 kW. Formula: 150 × 735.499 = 110,324.85 W. This is a common mid-size European hatchback or sedan power rating.
1 PS was defined as power to lift 75 kg by 1 meter in 1 second. Converting: 75 kgf × 9.80665 m/s² × 1 m/s = 735.49875 watts. This makes PS a clean metric unit based on SI physics.
