To calculate CFH from BTU, identify the BTU number, then utilize the equation by multiplying the BTU number by the appropriate factor. The process takes about 5 minutes and requires access to a calculator.
Know MoreFind the British Thermal Unit number that needs to be converted.
Calculate the conversion by placing the BTU number in the conversion equation. The equation explains that one cubic foot per hour, or CFH, is equal to 1,000 BTU of natural gas or 2,500 BTU of liquid propane when exposed to the environment.
Multiply the BTU number that needs to be converted by the correct factor from the equation, depending on whether natural gas or liquid propane is being used.
According to the Physics and Astronomy site at U.C. Irvine, one BTU is equivalent to 1055 joules and kilojoules/hr are converted to BTU/hr by dividing the kJ/hr by 1.055. Both kJ and BTU are units of energy so it is only possible to convert from kJ/hr to BTU/hr rather than from kJ/hr to BTU.
Full Answer >BTU is an abbreviation for British Thermal Unit, which is the international measure of energy. An air conditioner's BTU must be matched to the size of the room for adequate cooling. BTU tables estimate different energy requirements.
Full Answer >Calculating the BTU, or British thermal units, of a room helps you determine its heating or cooling requirements when purchasing and installing equipment. You need a tape measure, pen, paper and a knowledge of the quality of the room's insulation. You then need to calculate the cubic footage of the room and multiply this by its insulation value, adding or subtracting any relevant factors to find out the BTU. Relevant factors may include climate, sun exposure, occupancy and the purpose of the room.
Full Answer >The formula for calculating BTU loss or gain in converting CFM to BTU is temperature difference times actual CFM leakage times 1.08 equals BTU loss or gain. CFM is the actual cubic feet of air volume per minute pushed through the HVAC unit. BTU is the British thermal unit of heat removed from the room by the HVAC unit.
