Find the perfect AC size with our easy-to-use Air Conditioner Tonnage Calculator. Calculate the ideal tonnage for your room and stay cool efficiently!
Choosing the right size air conditioner for your room or home is very important. If the AC is too small, it won’t cool properly. If it’s too large, it will waste energy and increase your bills. To make this task easier, we have developed an Air Conditioner Tonnage Calculator. This tool helps you find the perfect AC size in just a few seconds based on your room dimensions and other factors.
In this guide, we will explain what AC tonnage means, how to calculate it manually, and how to use our calculator easily.
AC tonnage refers to the cooling capacity of an air conditioner. It is a measure of how much heat the AC can remove from a space in one hour. One ton equals 12,000 BTUs (British Thermal Units) per hour. In simple terms, the higher the tonnage, the more cooling power the AC has.
If you are wondering how many square feet a 3 ton AC cools, it can typically cover around 1,500 to 1,800 square feet, depending on factors like insulation, sunlight, and number of windows.
If you want to manually calculate the required tonnage for your room, you can use a simple formula.
The basic AC calculation formula is:
BTU = Area (in square feet) × BTU per square foot
For most climates, you can use 20 BTU per square foot as an average.
After finding the BTU, you can convert it into tons using:
Tonnage = BTU ÷ 12,000
Example Calculation:
If your room is 20 feet long and 20 feet wide, the area is 400 square feet.
400 sq ft × 20 BTU = 8,000 BTU
8,000 ÷ 12,000 = 0.67 tons
You would round up to 0.75 tons to ensure better cooling performance.
This method works well whether you need an AC tonnage calculator per square foot or an AC tonnage calculator per square meter (just convert meters to feet first).
Using our online tool is super easy. Follow these simple steps:
The calculator will instantly show you the recommended AC tonnage, total BTU needed, and a detailed breakdown of each factor. It even suggests the closest standard tonnage size available in the market for easy purchase.
Whether you are looking for a split AC tonnage calculator or an AC ton calculator for room size, our tool covers it all.
Finding the right size air conditioner is no longer confusing. Our Air Conditioner Tonnage Calculator makes it simple and fast. With just a few inputs, you can get an accurate recommendation that suits your room perfectly. Using the correct tonnage not only improves comfort but also saves money on electricity bills. Whether you are cooling a small bedroom, a large hall, or even a car, calculating the right AC tonnage is now easier than ever.
No more guessing or hiring expensive consultants. Use our tool today and enjoy perfect cooling every summer!
To calculate manually, multiply the room’s area by 20 BTU, then divide the total BTU by 12,000. The result is your required AC tonnage.
A 3 ton air conditioner can typically cool about 1,500 to 1,800 square feet, depending on ceiling height, insulation, sunlight exposure, and other factors.
A 2 ton AC is ideal for cooling around 800 to 1,200 square feet effectively.
A 20x20 room is 400 square feet. You will need approximately 8,000 BTUs to cool this room efficiently.
A BTU to ton calculator helps you easily convert BTUs to AC tons by dividing the BTUs by 12,000. One ton is equal to 12,000 BTUs per hour.
Yes, if you know the approximate interior space of your car, you can use the same method to estimate car air conditioner tonnage requirements.
