Convert US gallons per minute to Millilitres per minute
Convert US gallons per minute (gpm) to Millilitres per minute (mL/min) instantly and accurately.
Conversion Formula
mL/min = gpm × 3785.411784
About US gallons per minute
The US gallon per minute (gpm) equals 3.785411784×10⁻³/60 ≈ 6.309×10⁻⁵ m³/s, the dominant volumetric flow unit in US plumbing, HVAC, and water-treatment industries. EPA showerhead standards are set at 2.5 gpm; residential water meters size at 3/4"-1" for 5-20 gpm; municipal water-distribution design uses hundreds to thousands of gpm. 1 gpm ≈ 6.309×10⁻⁵ m³/s = 3.785 L/min.
About Millilitres per minute
The millilitre per minute (mL/min) equals 10⁻⁶/60 ≈ 1.667×10⁻⁸ m³/s, the standard flow rate unit for HPLC and preparative chromatography. A reverse-phase HPLC column (4.6 mm i.d.) operates at 1-2 mL/min; a cardiac output catheter measures 4 000-8 000 mL/min (= L/min). 1 mL/min ≈ 1.667×10⁻⁸ m³/s = 60 mL/h.
