Feet Per Minute to CFM Conversion Formula

Formula
$$\text{CFM} = \text{FPM} \times \left( \frac{\text{Area}}{144} \right)$$

Explanation: CFM (cubic feet per minute) is calculated by multiplying the airflow velocity in feet per minute (FPM) by the area in square inches divided by 144 to convert to square feet. This formula assumes consistent units and automatically handles unit conversions for various area measurements.

This converter is commonly used in HVAC systems, ventilation design, and industrial airflow calculations. It simplifies converting linear airflow speed (FPM) into volumetric flow rate (CFM), taking into account the cross-sectional area. The tool supports various units for area, including square millimeters, meters, feet, inches, and even acres — making it ideal for professionals and students alike.
