Below the calculator, we have also calculated a conversion chart for the most common airflow rates. Just input the m3/hr and you’ll get the converted CFM value. To help you out, we have prepared a meter cube per hour to CFM calculator: m3/h To CFM Calculator With a bit of math, we can derive this formula to convert m3/h to CFM:Įxample: An air purifier can produce an air flow of 200 m3/h.

Covert m3 into ft3 (cubic meter to cubic feet).

How many CFM is that? Here is the result from the m3/h to CFM calculator: 470 m3/h is equal to exactly 276.83 CFM.Īs you can see, we have to make two conversions: This is also a unit of air flow 1 CFM is equal to 1 cubic foot of air being moved in 1 hour. 1 m3/h is equal to 1 cubic meter of air being moved in 1 hour. m3/h or CMH ( Cubic Meters Per Hour) is the SI unit of air flow.Here are the units that we are converting: Below the calculator, you will also find a conversion chart with 1 m3/h to 3000 m3/h converted into CFM To help you out, we have created an m3/h to CFM calculator (just insert m3/h, get CFM automatically). That’s why it’s useful to convert m3/h to CFM. However, specification sheets of some devices like air purifiers may include m3/h but not CFM. CFM or cubic feet per minute is usually the more useful metric. Airflow is either measured in meter cube per hour (m3/h) or CFM.

Cubic meeter
