Formula
Formula
L/s = IGal/hr × 0.001262803
Multiply any value in Imperial gallons per hour by 0.001262803 to obtain the value in litres per second.
Worked example
Convert 1000 IGal/hr to L/s.
- 01Start with 1000 IGal/hr.
- 02Multiply by the conversion factor: 1000 × 0.001262803 = 1.2628 L/s.
Result1000 IGal/hr = 1.2628 L/s

FAQ
What is the conversion factor from IGal/hr to L/s?
1 IGal/hr equals 0.001262803 L/s. To convert, multiply the value in Imperial gallons per hour by 0.001262803.
How do I convert 1 IGal/hr to L/s?
1 IGal/hr = 0.0012628 L/s. For any value, multiply by 0.001262803.
How do I convert L/s back to IGal/hr?
Divide by the same factor — or equivalently, multiply by 791.8893. So 1 L/s = 791.889 IGal/hr.
When would I need to convert Imperial gallon per hour to litre 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/hr to L/s 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).
