This tool converts air velocity to cubic feet per minute (CFM) to help you quickly get accurate airflow measurements.
This calculator helps you convert air velocity in feet per minute (ft/min) to cubic feet per minute (CFM), a common measure used to quantify airflow in HVAC systems. To use the calculator:
- Enter the air velocity in ft/min in the first input field.
- Enter the cross-sectional area in sq ft in the second input field.
- Click on the “Calculate” button.
The result will be displayed in a table under the input fields. The table shows the entered values and the calculated CFM. This result is calculated using the formula:
CFM = Velocity (ft/min) × Area (sq ft)
Limitations: This calculator assumes uniform airflow across the cross-sectional area. Variations in velocity or area should be considered for more precise calculations.
