Working
- 1400 CFM x 1.69901 = 679.6 m³/h
Quick answer
One CFM equals 1.69901 cubic metres per hour.
m³/h = CFM x 1.69901
How to use the CFM to m³/h Calculator
- 1Enter the airflow rating in CFM from the fan or spec sheet.
- 2Read the equivalent in m³/h, the unit used on most European fans.
- 3Use L/s when comparing against ventilation codes written in metric.

Frequently asked questions
Why do European fans use m³/h?
Metric ventilation standards rate airflow per hour, so m³/h keeps the numbers convenient for whole-room air changes.
Is CFM the same as SCFM?
No — SCFM is corrected to standard temperature and pressure. At sea level and room temperature they are close enough for ventilation work.
