Standard AC Sizes

Thermal Heat Capacity

18,000 BTU/h

Total heat removal rate per hour (British Thermal Units).

Cooling Power (kW)

5.28 kW

1 Ton = 3.517 kW (equivalent thermal cooling output).

Cooling Capacity (Watts)

Tonnage to BTU Conversion

To convert air conditioner size from Tons to BTU/hr, multiply the tonnage by **12,000**.

In addition to HVAC systems, refrigeration tonnage is also used to size water chillers, walk-in coolers, and commercial ice makers. For example, a 5-ton cooling system handles 60,000 BTU/hr of heat load. Selecting the proper tonnage prevents issues like high energy bills and humidity buildup.
