Enter a value in cooling kW to see it in refrigeration tons.

Cooling kW explained

Cooling kW is cooling capacity in metric units: how much heat an AC removes.

One refrigeration ton is 12,000 BTU/hr, which equals 3.516853 cooling kW.

Conversion example

3.5 cooling kW equals 0.9952 refrigeration tons.

3.5 × 1,000 ÷ 0.2930710702 = 11,942.4957 BTU/hr; 11,942.4957 ÷ 12,000 = 0.9952 tons

Electrical input differs

Cooling kW is not the electricity the AC uses. Electrical input depends on efficiency and operating conditions.

To estimate electrical input, you need an efficiency rating or measured input watts.
