FAQ

What is the conversion factor from IGal/hr to ft³/min?
1 IGal/hr equals 0.002675728 ft³/min. To convert, multiply the value in Imperial gallons per hour by 0.002675728.
How do I convert 1 IGal/hr to ft³/min?
1 IGal/hr = 0.00267573 ft³/min. For any value, multiply by 0.002675728.
How do I convert ft³/min back to IGal/hr?
Divide by the same factor — or equivalently, multiply by 373.7301. So 1 ft³/min = 373.73 IGal/hr.
When would I need to convert Imperial gallon 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. IGal/hr to ft³/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).
