# Meter Cube Per Hour (CMH) To CFM Conversion (m3/hr To CFM)

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.

We can also use this basic conversion:

1 meter cube per hour is equal to 0.589 CFM.

To help you out, we have prepared a meter cube per hour to CFM calculator. How does m3/hr convert 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.

Note: m3/hr can also be abbreviated as CHM. That means that CHM to CFM conversion is the same as meter cube per hour to CFM, ie: 1 CHM is equal to 0.589 CFM.
