This will help you to select equipment, space plan for any mechanical rooms and …Tonnage = 60,000 BTUs / 12,000 = 5 tons. So, you would need an air conditioning unit with a capacity of 5 tons to adequately cool this room. FAQs. Q1. What is the relationship between BTUs and tonnage? A1. One ton of cooling capacity is equivalent to 12,000 BTUs per hour. To find the required tonnage, divide the total BTUs by 12,000. Q2. 3 tons – 1501 to 2100 square feet. 3.5 tons – 1801-2300 square feet. 4 tons – 2101 to 2700 square feet. 5 tons – 2401 to 3300 square feet. If you think your system may not be the correct size for your space, you are looking to get a new system or you have any questions regarding HVAC units, contact A/C Masters at 757-898-2894. The basic formula for determining the required tonnage of a central air conditioning system is as follows: ( ( House square footage times 30 then divided by 12,000 ) – 1.0 ) = Required Tonnage ... (such as 110 degrees in the desert) then don’t subtract 1 in the formula above. To determine a more accurate size for your region, use ….
