- 1. Cooling Capacity
Area To Be Cooled (Sq. Ft.) Capacity Needed (BTUs Per Hour) 400 to 450 sq. ft. 10,000 BTUs 450 to 550 sq. ft. 12,000 BTUs 550 to 700 sq. ft. 14,000 BTUs 700 to 1,000 sq. ft. 18,000 BTUs
- One BTU is the amount of heat energy required to raise one pound of water by 1ºF. Water weighs 8.33 pounds per gallon so we can calculate that one gallon of water requires 8.33 BTU to raise the temperature 1ºF. 1 Pound of Gas (1 PSI) = 28″ Water Column (w.c.) 1 Pound of Gas (1 PSI) = 16 Ounces (oz.)
- To determine the number of BTUs per square foot that you need to heat a room, simply multiply the square footage by 20 BTUs per square foot. For example, if a room has 1,000 square feet, you would require 20,000 BTUs to heat it.
Basics. A quick way to estimate the BTU needs of a 900-square foot space is to use the estimated capacities listed at the U.S. Environmental Protection Agency's Energy Star website. It states that a room with 700 to 1,000 square feet needs a furnace with a capacity of 18,000 BTUs.
- 10,000 BTUs will cover 300 sq. ft. (2,400 cubic feet) 12,000 BTUs will cover 400 sq. ft. (3,200 cubic feet) 13,000 BTUs will cover 450 sq. ft. (3,600 cubic feet) 14,000 BTUs will cover 500 sq. ft. (4,000 cubic feet)
- The industry rounded up to 12,000 Btu/h to reference 1-ton of air conditioner capacity. Therefore, a 2-ton A/C unit will remove 24,000 BTU's of heat per hour; a 3-ton A/C unit will remove 36,000 BTU's per hour and so on.

2. Find the correct cooling capacity for your room size
|Area To Be Cooled (square feet)||Capacity Needed (BTUs per hour)|
|300 up to 350||8,000|
|350 up to 400||9,000|
|400 up to 450||10,000|
|450 up to 550||12,000|
- The size of your space determines how much cooling capacity you need. Budget air conditioners range from 5,000 BTU, which can handle about 150 square feet, to 12,000 BTU, enough to cover about 550 square feet.
- BTU is an acronym for British Thermal Unit. Although its name seems to suggest otherwise, it is no longer commonly used in the United Kingdom. BTU is a unit of measurement for energy. One BTU is equal to the amount of energy used to raise the temperature of one pound of water one degree Fahrenheit.
- The quickest way to estimate the size of your garage heater is to follow the basic rule of 10 watts per square foot of space. If your garage is 24 ft. x 24 ft., for example, it has an area of 528 square feet (24 * 24 = 528) and would require a 5280 watt garage heater (528 * 10 = 5280).
