Convert airflow between Cubic Feet per Minute (CFM) and Cubic Meters per Hour (m³/hr)
Related Tools
The CFM to m³/hr Calculator helps you quickly convert Cubic Feet per Minute (CFM) to Cubic Meters per Hour (m³/hr) — two common airflow measurement units used in HVAC, ventilation, and industrial systems.
This tool is especially useful for engineers, technicians, and students who need accurate airflow conversions for system design and performance analysis.
How to Use the CFM to m³/hr Calculator
- Enter the airflow value in CFM (Cubic Feet per Minute).
- Click on the “Convert” or “Calculate” button.
- Instantly, the calculator will display the equivalent m³/hr (Cubic Meters per Hour) value.
- You can also use it in reverse to convert m³/hr to CFM. The tool supports both options.
Conversion Formula
To convert from CFM to m³/hr, use the simple formula below: m³/hr=CFM×1.699\text{m³/hr} = \text{CFM} \times 1.699m³/hr=CFM×1.699
(1 CFM = 1.699 m³/hr)
Example
If the airflow is 500 CFM, then: m³/hr=500×1.699=849.5 m³/hr\text{m³/hr} = 500 \times 1.699 = 849.5 \, \text{m³/hr}m³/hr=500×1.699=849.5m³/hr
So, 500 CFM = 849.5 m³/hr.
