What is an air conditioner BTU calculator?


An air conditioner BTU calculator is software designed to determine the required power of an air conditioner to cool a room based on the specific area and temperature conditions. One BTU (British Thermal Unit) is the amount of energy required to cool 1 pound of water through 1 degree Fahrenheit.

According to the BTU Calculator at Good Housekeeping, a sunny room with excellent insulation and an area of 700 to 1,000 square feet requires 19,800 BTUs to cool. Therefore, if a person is planning to buy an air conditioner for cooling such a room, its energy capacity should be at least 20,000 BTUs.
