m³/hr to CFM Converter – Airflow Unit Calculator for HVAC
This m³/hr to CFM converter helps HVAC engineers, designers, and students convert airflow from cubic meters per hour (m³/hr) to cubic feet per minute (CFM). It is useful for duct sizing, ventilation design, and HVAC system calculations.
m³/hr to CFM Calculator
Conversion Formula
The standard HVAC airflow conversion formula is:
CFM = m³/hr × 0.5886
This formula is derived from the relationship between cubic meters and cubic feet and is widely used in HVAC engineering practice.
Example Calculation
- Airflow = 1700 m³/hr
- CFM = 1700 × 0.5886
- Result = 1000.62 CFM
Where This Calculator Is Used
- HVAC duct sizing calculations
- Ventilation and fresh air design
- AHU and FCU airflow selection
- MEP and HVAC engineering projects
