About This Calculator
This calculator converts between cubic meters per hour (CMH or m³/h) and cubic feet per minute (CFM), two common units for measuring airflow in HVAC systems. CMH is standard in metric countries, while CFM is used in the United States.
CFM = CMH × 0.588578
CMH = CFM × 1.699
Where:
CFM = Cubic feet per minute
CMH = Cubic meters per hour (m³/h)
0.588578 = Conversion factor (CMH to CFM)
1.699 = Conversion factor (CFM to CMH)
