How to convert kilowatts to tons of refrigeration
Formula: TR = kW × 0.284345
Worked example: 100 kW → 100 × 0.284345 = 28.4345 TR
One ton of refrigeration is 3.517 kW of cooling. A 3-ton central air unit removes about 10.6 kW of heat from the house.

What is a kilowatt?
The kilowatt equals 1,000 watts. It rates electric heaters, car engines outside the US, solar installations and home electrical service. Running 1 kW for one hour uses 1 kilowatt-hour of energy.
What is a ton of refrigeration?
A ton of refrigeration is 12,000 BTU per hour, about 3.517 kW of cooling. It comes from the heat needed to melt one short ton of ice in a day. Central air systems for homes are sold in sizes of 1.5 to 5 tons.
