How do I convert kilowatts to horsepower?

To convert kilowatts to horsepower, multiply the power in kilowatts by 1.34102. For example, 75 kW = 75 × 1.34102 = 100.5765 hp.

What is the difference between horsepower and metric horsepower?

Horsepower (hp) is an imperial unit equal to 745.7 watts. Metric horsepower (PS) is a German unit equal to 735.5 watts. 1 hp = 1.01387 PS.

What is a ton of refrigeration?

A ton of refrigeration (TR) is a unit of power used in cooling. It represents the heat extraction rate of 1 ton (2000 lbs) of ice melting over 24 hours, equal to 12,000 BTU/h or 3.51685 kW.

How much power does a typical car engine produce?

Typical passenger car engines produce 100-300 horsepower (75-225 kW). Sports cars can produce 300-700+ hp (225-520+ kW), while economy cars might have 70-100 hp (52-75 kW).
