FAQ

What is the conversion factor from gpm (US) to m³/day?
1 gpm (US) equals 5.450993 m³/day. To convert, multiply the value in US gallons per minute by 5.450993.
How do I convert 1 gpm (US) to m³/day?
1 gpm (US) = 5.45099 m³/day. For any value, multiply by 5.450993.
How do I convert m³/day back to gpm (US)?
Divide by the same factor — or equivalently, multiply by 0.1834528. So 1 m³/day = 0.183453 gpm (US).
When would I need to convert US gallon per minute 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. gpm (US) to m³/day is a frequently needed conversion for flow datasheet preparation.
Is the conversion exact?
Yes. Both gpm (US) and m³/day are defined by exact SI relationships, so the displayed factor is exact (any rounding shown is only for display).
