About This Calculator
This calculator converts between liters per second (L/s) and cubic feet per minute (CFM), the two most common units for measuring airflow in HVAC systems. L/s is standard in metric countries, while CFM is used in the United States.
CFM = L/s × 2.11888
L/s = CFM ÷ 2.11888
Where:
CFM = Cubic feet per minute
L/s = Liters per second
2.11888 = Conversion factor
