FAQ

What is the conversion factor from cfm to ft³/hr?
1 cfm equals 60 ft³/hr. To convert, multiply the value in cubic feet per minute by 60.
How do I convert 1 cfm to ft³/hr?
1 cfm = 60 ft³/hr. For any value, multiply by 60.
How do I convert ft³/hr back to cfm?
Divide by the same factor — or equivalently, multiply by 0.01666667. So 1 ft³/hr = 0.0166667 cfm.
When would I need to convert cubic foot per minute to cubic foot 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 ft³/hr is a frequently needed conversion for flow datasheet preparation.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
