CFM to BTU Converter
Convert airflow from Cubic Feet per Minute (CFM) to heat load in British Thermal Units (BTU/hr).
Cubic Feet per Minute (CFM) to British Thermal Units (BTU) Conversion
To convert Cubic Feet per Minute (CFM) to British Thermal Units (BTU), you can use the following formula:
Conversion Formula
The formula becomes:
BTU = (CFM × ΔT × 1.08)Where:
- BTU = British Thermal Units
- CFM = Cubic Feet per Minute
- ΔT = Temperature difference in degrees Fahrenheit
Key Insight:
This formula helps determine the heating or cooling capacity required based on the airflow and temperature difference.
Cubic Feet per Minute (CFM)
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.
British Thermal Units (BTU)
A British Thermal Unit (BTU) is a unit of heat energy. It is defined as the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit.
- 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.
