Convert m3/h to CFM (cubic meters per hour, also written m3/hr or CMH, to cubic feet per minute), or CFM back to m3/h, for airflow and ventilation.

Also written m3/hr, m³/hr or CMH (cubic meters per hour).

m3/h to cfm Formula

The following formula is used to convert m3/h to cfm.

cfm = 0.5885778 × m3 / h
  • Where cfm is the cubic feet per minute
  • m3/h is the cubic meters per hour

To calculate cfm from m3/h multiply the m3/h by 0.5885778.

Example Problem

How to calculate cfm from m3/h?

First, determine the total number of cubic meters per hour.

For this example, the total number of m3/h is found to be 150.

Next, use the formula for the conversion above to determine the amount of cfm.

cfm = 0.5885778 * m3/h

cfm = 0.5885778 * 150

cfm = 88.2867
