CFM to m³/hr Converter (Airflow Calculator for HVAC)
The CFM to m³/hr Converter helps HVAC engineers, designers, and students quickly convert airflow values from CFM (Cubic Feet per Minute) to cubic meters per hour (m³/hr). This conversion is commonly required in HVAC design, duct sizing, and ventilation calculations.

CFM to m³/hr Conversion Formula
The standard HVAC airflow conversion formula is:
m³/hr = CFM × 1.699
This formula is based on international unit conversions and is widely used in HVAC engineering calculations.
Example Calculation
If airflow is 500 CFM:
- m³/hr = 500 × 1.699
- m³/hr = 849.5
So, 500 CFM = 849.5 m³/hr.
Where This Converter Is Used
- HVAC duct sizing calculations
- Ventilation system design
- Air handling unit (AHU) airflow selection
- Fan and blower selection
- Engineering reports and drawings
