FAQ

What is the conversion factor from cfs to IGal/hr?
1 cfs equals 22423.81 IGal/hr. To convert, multiply the value in cubic feet per second by 22423.81.
How do I convert 1 cfs to IGal/hr?
1 cfs = 22423.8 IGal/hr. For any value, multiply by 22423.81.
How do I convert IGal/hr back to cfs?
Divide by the same factor — or equivalently, multiply by 4.459546e-5. So 1 IGal/hr = 4.45955e-5 cfs.
When would I need to convert cubic foot per second to Imperial gallon 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. cfs to IGal/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).
