CFM to m³/h
Convert cubic feet per minute into cubic metres per hour. American and Taiwanese makers rate extractor fans, range hoods, air purifiers and PC fans in CFM, while ventilation drawings and European datasheets use m³/h.
Common values
Formula
m³/h = CFM × 1.69901079552
CFM is a volume flow and says nothing about pressure. Two fans with the same CFM behave differently once a filter or a long duct is in the way, so read the airflow together with the static pressure rating.
Frequently asked questions
Q. How many m³/h is 1 CFM?
1 CFM is 1.699 m³/h, and 10 CFM is 16.99 m³/h. Type any value in the box above to convert instantly.
Q. And how many CFM is 1 m³/h?
1 m³/h is 0.589 CFM. This converter works both ways, so typing in the right box updates the left one.
Q. Where is this unit used?
CFM is a volume flow and says nothing about pressure. Two fans with the same CFM behave differently once a filter or a long duct is in the way, so read the airflow together with the static pressure rating.
