Formula

Formula
gph (US) = mL/min × 0.01585032

Multiply any value in millilitres per minute by 0.01585032 to obtain the value in US gallons per hour.

Worked example

Convert 100 mL/min to gph (US).

  1. 01Start with 100 mL/min.
  2. 02Multiply by the conversion factor: 100 × 0.01585032 = 1.58503 gph (US).
Result100 mL/min = 1.58503 gph (US)

FAQ

What is the conversion factor from mL/min to gph (US)?
1 mL/min equals 0.01585032 gph (US). To convert, multiply the value in millilitres per minute by 0.01585032.
How do I convert 1 mL/min to gph (US)?
1 mL/min = 0.0158503 gph (US). For any value, multiply by 0.01585032.
How do I convert gph (US) back to mL/min?
Divide by the same factor — or equivalently, multiply by 63.0902. So 1 gph (US) = 63.0902 mL/min.
When would I need to convert millilitre per minute to US 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. mL/min to gph (US) is a frequently needed conversion for flow datasheet preparation.
Is the conversion exact?
Yes. Both mL/min and gph (US) are defined by exact SI relationships, so the displayed factor is exact (any rounding shown is only for display).
