How to Convert KW to HP for Air Conditioners

by Mark Kennan, Demand Media

    Horsepower and kilowatts are two units used to measure power. For an air conditioner, horsepower is generally used to represent the speed that the AC motor is running at while kilowatts refers to the electrical use of the motor. The higher the motor speed, the more electricity is being used. To convert from kW to HP for air conditioners, you need to know the number of kW being converted.

    Step 1

    Consult your owner's manual of your air conditioner to determine the number of kilowatts being used.

    Step 2

    Divide the number of kilowatts by 2.55 to convert from kW to HP. For example, if your air conditioner's capacity was 10 kW, you would divide 10 by 2.55 to get about 3.92 HP.

    Step 3

    Multiply the number of kW by 0.392 as an alternative method to convert from kW to HP. For example, if your air conditioner's capacity was 10 kW, you would multiply 10 by 0.392 to get about 3.92 HP.
