How to Convert m³/hr to CFM
Divide the airflow in cubic metres per hour by 1.699011, or multiply it by 0.588578, to get cubic feet per minute. m³/hr is also written as CMH.
Example: a fan rated at 1,700 m³/hr moves 1,700 × 0.588578 = 1,000.6 CFM.
| Airflow (m³/hr) | Airflow (CFM) | Airflow (L/s) |
|---|---|---|
| 100 | 58.86 | 27.78 |
| 500 | 294.3 | 138.9 |
| 1,000 | 588.6 | 277.8 |
| 1,700 | 1,001 | 472.2 |

Frequently Asked Questions (FAQs)
To convert Cubic Feet per Minute (CFM) to cubic meters per hour (m³/hr), you need to multiply the CFM value by 1.69901. This simple conversion factor is derived from the fact that one cubic meter is roughly 35.3147 cubic feet, and there are 60 minutes in an hour.
CFM stands for Cubic Feet per Minute, which is a standard measurement of airflow volume in HVAC systems. It indicates how much air a fan or air conditioning unit can move in one minute. Proper CFM is essential for ensuring efficient cooling, heating, and adequate indoor air quality in any space.
Converting CFM to cubic meters per hour is often necessary when working with international HVAC equipment or specifications that use the metric system. It ensures compatibility and accurate sizing when comparing air handling units, fans, or ventilation systems across various global markets.
An airflow of 1000 CFM is relatively substantial and is typically sufficient to cool or heat a space of about 1000 square feet, depending on the ceiling height and HVAC load requirements. It is commonly found in medium residential air conditioning units or small commercial ventilation systems.
One Cubic Foot per Minute (CFM) is exactly equal to 1.69901 cubic meters per hour (m³/hr). This basic conversion rate helps engineers and technicians quickly translate airflow measurements between the imperial and metric systems, ensuring accurate calculations for ventilation and ductwork design.
To convert Cubic Feet per Minute (CFM) to Cubic Meters per Hour (CMH), you need to multiply the CFM value by roughly 1.699. This standard conversion factor bridges the gap between the imperial measurement of airflow per minute and the metric standard of overall volumetric air movement per hour.
