    How to use the Tons (AC) to kW Converter

    1. Type a value in the Tons of refrigeration box. The kilowatts result appears instantly.
    2. Going the other way? Type in the Kilowatts box, or press the ⇄ swap button.
    3. Set the precision with the decimal places menu.
    4. Check the working in the step-by-step box, then press Copy result or click any row in the tables below.

    Tons of refrigeration to kilowatts formula

    kW = TR × 3.516852842
    1. Take the value in tons of refrigeration.
    2. Multiply it by 3.516852842 (the number of kilowatts in one ton of refrigeration).

    Example: 3 TR × 3.516852842 = 10.5506 kW.

    Reverse formula (kilowatts to tons of refrigeration): TR = kW ÷ 3.516852842. Example: 8.79213 kW ÷ 3.516852842 = 2.5 TR.

    Quick mental estimate: multiply by about 3.5. For exact answers use the converter above.

    About tons of refrigeration and kilowatts

    Tons of refrigeration (TR). A ton of refrigeration (TR) is 12,000 BTU per hour, about 3.517 kW: the rate of heat removal needed to melt one short ton of ice in 24 hours. Air conditioners are sized in tons.

    Kilowatts (kW). The kilowatt is 1,000 watts. Engines, motors, heaters and EV chargers are rated in kW.

    Frequently asked questions

    1 ton of refrigeration equals how many kilowatts?

    One ton of refrigeration equals 3.51685 kilowatts.

    How do you convert tons of refrigeration to kilowatts?

    Multiply the number of tons of refrigeration by 3.516852842. For example, 3 TR × 3.516852842 = 10.5506 kW.

    What is 2.5 tons of refrigeration in kilowatts?

    2.5 TR is 8.79213 kW.

    How do I convert kilowatts back to tons of refrigeration?

    Divide by 3.516852842, or press the ⇄ swap button above. For example, 8.79213 kW ÷ 3.516852842 = 2.5 TR.

    What does a '3-ton' air conditioner mean?

    A ton of cooling is 12,000 BTU per hour, so a 3-ton AC removes 36,000 BTU/h of heat, about 10.55 kW. It says nothing about the unit's weight.
