How to Calculate Tonnage of AC for a Room: Step-by-step guide

As the summer months approach, many of us are starting to think about how we can keep our homes cool and comfortable during the hot and humid days. The air conditioner is an essential appliance that helps us beat the heat and maintain a pleasant indoor environment.

However, choosing the right size of AC for your room is crucial to ensure efficient cooling, comfort, and energy savings. One of the critical factors that determine the suitability of an AC for a room is its tonnage.

Tonnage refers to the cooling capacity of an air conditioner and is measured in BTU (British Thermal Units) per hour.

Calculating the tonnage of AC required for your room size can be a daunting task, but it’s essential to get it right. Let’s find the step-by-step process to calculate the tonnage of AC required for your room.

Step 1: Measure the Dimensions of the Room

Accurately measure the length, width, and height of the room in feet. Write down these measurements to use for calculations later.

Step 2: Calculate Room Volume

Multiply all three dimensions together to get the total volume of air in cubic feet (ft3).

For example, if a room is 20ft (ca. 6 m) long x 10ft (ca. 3 m) wide x 8ft (2.44 m) high, its volume would be 1,600 cubic feet (ca. 45 m³) (20 × 10 × 8 = 1,600)

Step 3: Convert Volume to Tonnage

To calculate tonnage from volume, you need to multiply by 12 – this is because one ton equals 12 cubic feet per minute (CFM).

So in this case it would be 1,600 ft3 multiplied by 12 which gives 19200 CFM or 19.

Result: You will require 2 tons of AC capacity for that particular room size.
