Formula

Formula
IGal/min = L/min × 0.2199692

Multiply any value in litres per minute by 0.2199692 to obtain the value in Imperial gallons per minute.

Worked example

Convert 100 L/min to IGal/min.

  1. 01Start with 100 L/min.
  2. 02Multiply by the conversion factor: 100 × 0.2199692 = 21.9969 IGal/min.
Result100 L/min = 21.9969 IGal/min

FAQ

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