Step 1: Measure The Square Footage (Length, Width, Height Exact To 0.25 Ft)
Step 1: Measure The Square Footage (Length, Width, Height Exact To 0.25 Ft)
1Square Footage = Measured Length x Measured Width. 2) Square Footage = 16 3/4 ft (Length) x 14 1/2 ft (Width) = 243 sq ft. 3) BTU Requirement = 500 sq ft x 20 BTU per sq ft = 10,000 BTU. 4) Accurate BTU Calculation = 20,000 BTU * 1.1 + 600 BTU = 22,600 BTU.
How do I know my AC capacity?
Simply divide the BTUs by 12,000 to calculate the tonnage of your unit. For example, if your air conditioner is 36,000 BTUs, you have a 3-ton unit. Some manufacturers bury tonnage or BTU information in their model numbers. Look for an even, two-digit number between 18 and 60.
How do you calculate AC capacity in tons?
An air conditioner's model number is a string of numbers and letters. Within the string, you should see an even, two-digit number. Add three zeroes to the number and you have the BTU rating. Divide the two-digit number by 12, and you have the tonnage.
How do you calculate aircon capacity?
How To Measure What Size Air Conditioner You Need? To calculate the size of the air conditioner you need for a room, first, multiply the length of the room with its width. Then multiply it with 25 BTU to get the ample cooling for the room under different weather conditions.
Summary of the 3 simple steps to calculate AC tonnage:
Find the square footage of the area you want to cool.
Multiply the number of square feet you are cooling by 25. Example: if your home has 1,500 sq. feet, you would like to cool, 1,500 multiplied by 25 would be 37,500.
Lastly, divide that BTU number by 12,000.
