Enter the cooling capacity in tons into the calculator to determine the equivalent power in kilowatts (kW). This calculator helps in converting the cooling capacity of HVAC systems from tons to kW.

Tons to kW Conversion Formula

The following formula is used to convert cooling capacity from tons to kilowatts (kW):

P (kW) = C (tons) * 3.517

Variables:

  • P is the power in kilowatts (kW)
  • C is the cooling capacity in tons
  • 3.517 is the conversion factor from tons to kW

To convert tons to kW, multiply the cooling capacity in tons by the conversion factor of 3.517.

What is Cooling Capacity in Tons?

Cooling capacity in tons is a unit of power used in the United States to describe the rate at which an air conditioning system can remove heat from a space. One ton of cooling is equal to the amount of heat absorbed by one ton of ice causing it to melt completely over a period of 24 hours. It is equivalent to a heat absorption rate of 12,000 BTU per hour.

How to Convert Tons to kW?

The following steps outline how to convert the cooling capacity from tons to kilowatts (kW).


  1. First, determine the cooling capacity in tons.
  2. Next, use the conversion formula: P (kW) = C (tons) * 3.517.
  3. Finally, calculate the power in kilowatts (kW).
  4. After inserting the variable and calculating the result, check your answer with the calculator above.

Example Problem :

Use the following variable as an example problem to test your knowledge.

Cooling capacity (C) = 5 tons

Using the conversion formula: P (kW) = 5 tons * 3.517 = 17.585 kW
