FAQ

What is the conversion factor from ft³/hr to IGal/min?
1 ft³/hr equals 0.1038139 IGal/min. To convert, multiply the value in cubic feet per hour by 0.1038139.
How do I convert 1 ft³/hr to IGal/min?
1 ft³/hr = 0.103814 IGal/min. For any value, multiply by 0.1038139.
How do I convert IGal/min back to ft³/hr?
Divide by the same factor — or equivalently, multiply by 9.632619. So 1 IGal/min = 9.63262 ft³/hr.
When would I need to convert cubic foot per hour to Imperial gallon 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 IGal/min 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).
