The British thermal unit (BTU or Btu) is a measure of heat, which is measured in units of energy. It is defined as the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit. It is also part of the United States customary units. The modern SI unit for energy is the joule (J); one BTU equals about 1,055 J (varying within the range of 1,054–1,060 J depending on the specific definition; see below). WebApr 17, 2024 · If the outside temperature is 23, and the inside temperature is 60 degrees Fahrenheit, and the actual leakage is 14,200 CFM, the calculation would be (60-23) x 1.08 = BTU loss or gain or 37 x 14,200 x 1.08 = 567,432 BTU loss or gain per hour. himoinsa sl
