Formula

Formula
IGal/hr = L/hr × 0.2199692

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

Worked example

Convert 100 L/hr to IGal/hr.

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

FAQ

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