Formula

Formula
IGal/min = L/s × 13.19815

Multiply any value in litres per second by 13.19815 to obtain the value in Imperial gallons per minute.

Worked example

Convert 1 L/s to IGal/min.

  1. 01Start with 1 L/s.
  2. 02Multiply by the conversion factor: 1 × 13.19815 = 13.1982 IGal/min.
Result1 L/s = 13.1982 IGal/min

FAQ

What is the conversion factor from L/s to IGal/min?
1 L/s equals 13.19815 IGal/min. To convert, multiply the value in litres per second by 13.19815.
How do I convert 1 L/s to IGal/min?
1 L/s = 13.1982 IGal/min. For any value, multiply by 13.19815.
How do I convert IGal/min back to L/s?
Divide by the same factor — or equivalently, multiply by 0.07576817. So 1 IGal/min = 0.0757682 L/s.
When would I need to convert litre per second to Imperial gallon 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. L/s to IGal/min 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).
