Power Unit Conversion Reference

Power is the rate at which energy is transferred or work is done. It appears in electrical engineering (watts), automotive (horsepower), and HVAC (BTU/hr). This converter handles all major power units.

Key Conversion Factors

FromTo Watts
1 kilowatt (kW)1,000 W
1 megawatt (MW)1,000,000 W
1 mechanical horsepower (hp)745.7 W
1 metric horsepower (PS)735.5 W
1 BTU/hour0.29307 W
1 calorie/second4.1868 W

Mechanical vs Metric Horsepower

The US uses mechanical horsepower (1 hp = 745.7 W), while Europe and Asia traditionally use metric horsepower or PS (1 PS = 735.5 W). Car specifications in Germany show PS; US specs show hp.

Practical Examples

  • 100 hp car engine = 74.6 kW
  • Home microwave (1000 W) = 1.34 hp
  • Wind turbine (2 MW) = 2,000 kW
  • LED bulb (10 W) = 34.1 BTU/hr
