The British Thermal Unit (BTU) is the power that your AC will consume to push heat from your room per square foot. On the other hand, tonnage is the capacity of an air conditioner. Both these terms are interlinked. Having a little knowledge of both these terminologies, you can easily invest in a good air conditioner for you. Here is how to take out the BTU. 

BTU = Length of the room (ft.) × Width (ft.)/25

When you succeed in taking out the right BTU required to cool your room, you can also use it to calculate the tonnage of the required air conditioner. According to the research, 1 ton equals 12000 BTU per hour. It means that you’ll need about 0.0016 tons to cool per square foot.

From this perspective, a 3 ton AC will be enough for 1800 square feet. If the area of your room is equal to or slightly less than this measurement, a three-ton AC will be sufficient for it.
