FAQ

What is the conversion factor from gph (US) to m³/day?
1 gph (US) equals 0.09084988 m³/day. To convert, multiply the value in US gallons per hour by 0.09084988.
How do I convert 1 gph (US) to m³/day?
1 gph (US) = 0.0908499 m³/day. For any value, multiply by 0.09084988.
How do I convert m³/day back to gph (US)?
Divide by the same factor — or equivalently, multiply by 11.00717. So 1 m³/day = 11.0072 gph (US).
When would I need to convert US gallon per hour to cubic metre per day?
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/day is a frequently needed conversion for flow datasheet preparation.
Is the conversion exact?
Yes. Both gph (US) and m³/day are defined by exact SI relationships, so the displayed factor is exact (any rounding shown is only for display).
