FAQ

What is the conversion factor from IGal/min to cfs?
1 IGal/min equals 0.002675728 cfs. To convert, multiply the value in Imperial gallons per minute by 0.002675728.
How do I convert 1 IGal/min to cfs?
1 IGal/min = 0.00267573 cfs. For any value, multiply by 0.002675728.
How do I convert cfs back to IGal/min?
Divide by the same factor — or equivalently, multiply by 373.7301. So 1 cfs = 373.73 IGal/min.
When would I need to convert Imperial gallon per minute to cubic foot per second?
Flow-rate conversions show up in pump curve interpretation, control valve sizing (Cv vs Kv), and aligning vendor specifications with process simulation outputs. IGal/min to cfs 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).
