How to Use: Enter the airflow in CFM. Enter the air velocity in FPM. Click the "Calculate" button to find the recommended duct size. Example: For instance, if the airflow is 1200 CFM and the air velocity is 800 FPM, the calculation would be: (1200 / 800) * 144 = 216. Therefore, the recommended duct size is 216 square inches.
