FAQ

What is the conversion factor from L/s to IGal/hr?
1 L/s equals 791.8893 IGal/hr. To convert, multiply the value in litres per second by 791.8893.
How do I convert 1 L/s to IGal/hr?
1 L/s = 791.889 IGal/hr. For any value, multiply by 791.8893.
How do I convert IGal/hr back to L/s?
Divide by the same factor — or equivalently, multiply by 0.001262803. So 1 IGal/hr = 0.0012628 L/s.
When would I need to convert litre 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. L/s to IGal/hr is a frequently needed conversion for hydraulic sizing.
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).
