The Convert FPM to CFM Calculator serves as a valuable tool for engineers, HVAC technicians, and anyone involved in air flow systems. It simplifies the process of converting the velocity of air from feet per minute (FPM) to cubic feet per minute (CFM), which is essential for determining the volumetric flow rate of air within a given space. By inputting the velocity of air (FPM) and the cross-sectional area through which the air is flowing (measured in square feet), users can quickly calculate the corresponding CFM value.
Formula of Convert FPM to CFM Calculator
The formula used by the Convert FPM to CFM Calculator is as follows:
CFM = (FPM * Area) / 144
Where:
- FPM represents the velocity of air in feet per minute.
- Area denotes the cross-sectional area through which the air is flowing, measured in square feet.

Example of Convert FPM to CFM Calculator
Let's consider an example to illustrate how the Convert FPM to CFM Calculator works in practice:
Suppose we have an air duct with a velocity of 500 feet per minute (FPM) and a cross-sectional area of 10 square feet. Using the formula mentioned earlier:
CFM = (500 * 10) / 144 = 5000 / 144 ≈ 34.72 CFM
Therefore, the cubic feet per minute (CFM) of air flowing through the duct is approximately 34.72 CFM.
Most Common FAQs
Converting FPM to CFM is crucial for determining the volume of air flow within a given space. This information is essential for HVAC system design, ventilation calculations, and ensuring adequate air circulation for comfort and safety.
The cross-sectional area of a duct can be calculate by multiplying its width by its height (for rectangular ducts). Can also by using the formula for the area of a circle (π * radius^2) for circular ducts.
CFM calculations are widely use in HVAC system design, industrial ventilation, exhaust fan sizing, air quality monitoring, and determining air exchange rates in enclosed spaces.
