How many btuh in cfm?

To convert CFM (cubic feet per minute) to BTU/hr (British thermal units per hour), you can use the formula: BTU/hr = CFM × ΔT × 1.08, where ΔT is the temperature difference in degrees Fahrenheit between the inlet and outlet air. The constant 1.08 is derived from the specific heat of air and the conversion factors of CFM to BTU. Therefore, the exact number of BTU/hr from CFM depends on the temperature difference you are considering.
