FAQ

What is the conversion factor from IGal/min to L/min?
1 IGal/min equals 4.54609 L/min. To convert, multiply the value in Imperial gallons per minute by 4.54609.
How do I convert 1 IGal/min to L/min?
1 IGal/min = 4.54609 L/min. For any value, multiply by 4.54609.
How do I convert L/min back to IGal/min?
Divide by the same factor — or equivalently, multiply by 0.2199692. So 1 L/min = 0.219969 IGal/min.
When would I need to convert Imperial gallon per minute to litre 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/min to L/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).
