British Thermal Units (BTU) to Cubic Feet per Minute (CFM) Conversion

To convert British Thermal Units (BTU) to Cubic Feet per Minute (CFM), you can use the following formula:

The formula becomes:

CFM = (BTU × 60) ÷ (ΔT × 1.08)

Where:

BTU is a unit of heat energy:

Scientific Definition: The amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit.
Common Usage: Used in heating and cooling systems, such as HVAC units and refrigerators.

CFM is a measure of airflow:

Scientific Definition: The volume of air that flows in one minute, measured in cubic feet.
Common Applications: Used in HVAC systems to specify airflow rates for heating and cooling.
