How much ton AC is suitable for your room

A simple calculation is as follows

Multiply the length, breadth and height of the room (take units as feet). Then divide this by 1000 to get the ton capacity

Example if the room’s size is 10 feet by 10 feet by 10 feet

So 10 X 10 X 10 comes out to 1000, divide this by 1000 the answer comes to 1. So your as tonnage requirement is one ton

Another example room size 12 feet by 12 feet by 9 feet. The multiplication comes out to be 1290. Dividing this by 1000 leads to 1.2. so tonnage requirement is 1.2 ton. If there is direct sunlight in the room and  /or the air conditioner is exposed to sun, or you stay on the top floor where roof heats up, go for 1.5 tom AC otherwise go for 1 ton AC as air conditioners are available in 0.75 ton. 1 ton and 2 ton and above capacity only
