Conversion / Calculation Guide
To convert CFM to m³/hr, use this standard formula:
Step-by-Step Conversion Example
Let’s convert 100 CFM to m³/hr:
Step 1: Write the formula
m³/hr = CFM × 1.699
Step 2: Insert the value
m³/hr = 100 × 1.699
Step 3: Calculate
m³/hr = 169.9
Step 4: Final Answer
100 CFM = 169.9 m³/hr
Why This Conversion Matters
- HVAC engineers use it for airflow design.
- It helps in duct sizing and ventilation planning.
- It ensures proper air circulation in buildings.
