How to convert CFM to m3/h?
CFM stands for Cubic Feet per Minute, a standard imperial unit for measuring airflow. In the metric system, engineers use Cubic Meters per Hour (m³/h). This conversion is essential when designing HVAC systems or specifying industrial air compressors for international facilities.
1 CFM = 1.69901 m³/h
1 m³/h = 0.588578 CFM
Airflow Reference Table
Typical airflow requirements for industrial applications:
| Airflow (CFM) | Metric (m3/h) - Approx | Industrial Context |
|---|---|---|
| 5 CFM | 8.5 m3/h | Small pneumatic nailer |
| 25 CFM | 42.5 m3/h | Industrial impact wrench (1/2") |
| 100 CFM | 169.9 m3/h | Medium industrial compressor |
| 500 CFM | 849.5 m3/h | Paint booth ventilation fan |
| 2000 CFM | 3,398 m3/h | Large warehouse exhaust unit |
Airflow in Industrial Processes
Why accurate flow calculation is vital for your facility:
- Pneumatic Tooling: Every tool has a specific CFM requirement. If the supply (measured in m³/h) is lower than the tool's demand, performance drops and equipment can be damaged.
- Dust Collection: Exhaust systems in woodworking or chemical plants require a minimum "capture velocity" calculated in CFM to ensure harmful particles are removed from the air.
- HVAC Duct Sizing: Sizing ductwork requires a precise understanding of the air volume to be moved to maintain room pressure and temperature.
FAQ: Airflow & Volumetric Units
What is the difference between CFM and SCFM?
CFM measures the actual volume of air, while SCFM (Standard CFM) is the airflow corrected to standard conditions (temperature and pressure). In many industrial specs, they are treated as similar for quick estimates.
How do I convert m3/min to CFM?
To convert cubic meters per minute (m3/min) to CFM, you multiply by 35.31.
