FAQ

What is the conversion factor from gph (US) to m³/min?
1 gph (US) equals 6.30902e-5 m³/min. To convert, multiply the value in US gallons per hour by 6.30902e-5.
How do I convert 1 gph (US) to m³/min?
1 gph (US) = 6.30902e-5 m³/min. For any value, multiply by 6.30902e-5.
How do I convert m³/min back to gph (US)?
Divide by the same factor — or equivalently, multiply by 15850.32. So 1 m³/min = 15850.3 gph (US).
When would I need to convert US gallon per hour to cubic metre 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. gph (US) to m³/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).
