FAQ

What is the conversion factor from gpm (US) to mL/min?
1 gpm (US) equals 3785.412 mL/min. To convert, multiply the value in US gallons per minute by 3785.412.
How do I convert 1 gpm (US) to mL/min?
1 gpm (US) = 3785.41 mL/min. For any value, multiply by 3785.412.
How do I convert mL/min back to gpm (US)?
Divide by the same factor — or equivalently, multiply by 0.0002641721. So 1 mL/min = 0.000264172 gpm (US).
When would I need to convert US gallon per minute to millilitre 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. gpm (US) to mL/min is a frequently needed conversion for flow datasheet preparation.
Is the conversion exact?
Yes. Both gpm (US) and mL/min are defined by exact SI relationships, so the displayed factor is exact (any rounding shown is only for display).
