CFM to m³/s Conversion FAQ
Everything you need to know about converting volume flow rates for your engineering or HVAC project.
To convert Cubic Feet Per Minute (CFM) to Cubic Metres Per Second (m³/s), multiply the CFM value by 0.000471947. The formula is: m³/s = CFM × 0.000471947.
There are approximately 2,118.88 CFM in 1 cubic metre per second (m³/s). This is calculated by dividing 1 by the conversion factor (1 / 0.000471947).
CFM is commonly used in the US and UK for HVAC and ventilation, while m³/s is the standard SI unit used globally in engineering, scientific research, and industrial applications. Converting ensures accurate equipment sizing and compliance with international standards.
The mathematical conversion factor (0.000471947) is based on geometric volume and time, so it remains constant. However, actual air mass flow rate will vary with temperature and pressure, which is why Standard CFM (SCFM) is often used in precise engineering calculations.
