FAQ

What is the conversion factor from cfm to m³/hr?
1 cfm equals 1.699011 m³/hr. To convert, multiply the value in cubic feet per minute by 1.699011.
How do I convert 1 cfm to m³/hr?
1 cfm = 1.69901 m³/hr. For any value, multiply by 1.699011.
How do I convert m³/hr back to cfm?
Divide by the same factor — or equivalently, multiply by 0.5885778. So 1 m³/hr = 0.588578 cfm.
When would I need to convert cubic foot per minute to cubic metre per hour?
Flow-rate conversions show up in pump curve interpretation, control valve sizing (Cv vs Kv), and aligning vendor specifications with process simulation outputs. cfm to m³/hr is a frequently needed conversion for flow datasheet preparation.
Is the conversion exact?
Yes. Both cfm and m³/hr are defined by exact SI relationships, so the displayed factor is exact (any rounding shown is only for display).
