CFM to L/s Flow Rate Converter

This calculator converts air flow rates from Cubic Feet per Minute (CFM) to Liters per Second (L/s). CFM is commonly used in HVAC systems in imperial units, while L/s is the metric equivalent used in international engineering applications. The conversion is essential for cross-referencing ventilation specifications between different measurement systems.
Conversion Formula
L/s = CFM × 0.47194667

This conversion factor is derived from: 1 ft³ = 28.317 liters and 1 minute = 60 seconds

Volume Conversion
1 ft³ = 28.317 L
Time Conversion
1 min = 60 sec
Calculation Example
Input: 100 CFM
Calculation: 100 × 0.47194667 = 47.19 L/s
Result: 47.19 Liters per Second
Technical Note: The calculator provides precise decimal control for engineering accuracy. CFM measurements are typically used for air handling units, exhaust fans, and HVAC equipment sizing, while L/s is standard in metric building codes and international ventilation standards.
