FAQ

What is the conversion factor from m³/hr to IGal/hr?
1 m³/hr equals 219.9692 IGal/hr. To convert, multiply the value in cubic metres per hour by 219.9692.
How do I convert 1 m³/hr to IGal/hr?
1 m³/hr = 219.969 IGal/hr. For any value, multiply by 219.9692.
How do I convert IGal/hr back to m³/hr?
Divide by the same factor — or equivalently, multiply by 0.00454609. So 1 IGal/hr = 0.00454609 m³/hr.
When would I need to convert cubic metre 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. m³/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).
