FAQ
What is the conversion factor from ft³/hr to cfm?
1 ft³/hr equals 0.01666667 cfm. To convert, multiply the value in cubic feet per hour by 0.01666667.
How do I convert 1 ft³/hr to cfm?
1 ft³/hr = 0.0166667 cfm. For any value, multiply by 0.01666667.
How do I convert cfm back to ft³/hr?
Divide by the same factor — or equivalently, multiply by 60. So 1 cfm = 60 ft³/hr.
When would I need to convert cubic foot per hour to cubic foot per minute?
Flow-rate conversions show up in pump curve interpretation, control valve sizing (Cv vs Kv), and aligning vendor specifications with process simulation outputs. ft³/hr to cfm 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).
