Understanding CFM to m3/hr Conversion
CFM (Cubic Feet per Minute) is a unit used to measure airflow in the imperial system, whereas m3/hr (Cubic Meters per Hour) is its metric counterpart. The formula for conversion is:
1 CFM = 1.699 m3/hr
Using this conversion factor, you can easily convert CFM to m3/hr and vice versa.

Common Air Flow Conversions
- 1 CFM to m3/hr = 1.699 m3/hr
- 100 CFM to m3/h = 169.9 m3/h
- 500 m3/h to CFM = 294.12 CFM
- 900 CFM to m3/h = 1529.1 m3/h
How to Convert Air Flow CFM to m3/hr
To manually convert CFM to m3/hr, use this formula:
m3/hr = CFM × 1.699
For example, if you have 500 CFM:
500 × 1.699 = 849.5 m3/hr
To convert m3/hr to CFM, use this formula:
CFM = m3/hr ÷ 1.699
For example, if you have 1000 m3/hr:
1000 ÷ 1.699 = 588.58 CFM
Why Air Flow Conversion is Important
- Ensures accurate HVAC system sizing
- Helps in industrial ventilation planning
- Essential for fan and blower selection
- Improves energy efficiency
