CFM to m³/s Conversion Formula:
| From: | To: |
Air Flow Rate Conversion between CFM (Cubic Feet Per Minute) and m³/s (Cubic Meters Per Second) is essential for HVAC system design, ventilation calculations, and air handling applications across different measurement systems.
The calculator uses the conversion formula:
Where:
Explanation: This conversion factor is derived from the relationship between cubic feet and cubic meters (1 m³ = 35.3147 ft³) and the conversion between seconds and minutes (1 minute = 60 seconds).
Details: Accurate air flow rate conversion is crucial for HVAC system design, duct sizing, fan selection, ventilation requirements, and ensuring proper air circulation in residential, commercial, and industrial applications.
Tips: Enter the air flow rate in cubic meters per second (m³/s). The value must be positive and greater than zero. The calculator will automatically convert to cubic feet per minute (CFM).
Q1: What Is CFM Used For In HVAC?
A: CFM measures air flow volume and is used for sizing ducts, selecting fans, determining ventilation rates, and calculating air changes per hour in HVAC systems.
Q2: When Should I Use m³/s Vs CFM?
A: Use m³/s in metric system countries and for scientific calculations, while CFM is commonly used in the United States and for practical HVAC applications.
Q3: What Are Typical CFM Values For Residential HVAC?
A: Typical residential systems range from 400-2000 CFM depending on home size, with average values around 1000-1500 CFM for standard single-family homes.
Q4: How Accurate Is This Conversion?
A: The conversion factor 2118.88 provides high accuracy for most engineering and HVAC applications, with precision to two decimal places.
Q5: Can I Convert CFM Back To m³/s?
A: Yes, use the reverse formula: m³/s = CFM ÷ 2118.88 for accurate conversion back to cubic meters per second.
