Before you can calculate the tonnage of AC required for your room, you need to measure the room dimensions accurately. Use a tape measure to measure the length, width, and height of the room in feet.

Matching Room Measurements To Btus

After measuring the room, you need to determine the BTU (British Thermal Units) required to cool the space effectively. BTUs measure the cooling capacity of an air conditioner and are directly related to the size of the room. Use the following table to match the room measurements to the appropriate BTU range:

Room Area (in square feet) BTU Range
100-250 5,000-6,000 BTUs
250-400 7,000-8,000 BTUs
400-650 9,000-12,000 BTUs
650-1,000 13,000-16,000 BTUs

Translating Btus To Ac Tonnage

Once you have determined the BTU range for your room, you can translate it into AC tonnage. One ton of cooling capacity is equivalent to 12,000 BTUs. To calculate the tonnage, divide the BTU range by 12,000. For example, if your room requires 9,000-12,000 BTUs, you would divide that range by 12,000 to get an AC tonnage of 0.75-1 ton.
