Airflow is either measured in **meter cube per hour** or **CFM**. CFM or cubic feet per minute is usually the more useful metric. However, specification sheets of some devices like air purifiers may include meter cube per hour (m3/hr) but not CFM.

That’s why it’s useful to convert meter cube per hour to CFM.

*How do you convert m3/hr to CFM?*

We can use this formula to convert meter cube per hour to CFM:

**CFM = m3/hr / 1.699**

*Example:* An air purifier can produce an airflow of 200 meter cube per hour. That converts to 200/1.699 = 118 CFM.

To help you out, we have prepared a meter cube per hour to CFM calculator. What is m3/hr in CFM? Just input the m3/hr and you’ll get the converted CFM value. Below the calculator, we have also calculated a conversion chart for the most common airflow rates.
