Conversion Formula
mL/min = gpd × 2.628758183
About US gallons per day
The US gallon per day (gpd) equals 3.785411784×10⁻³/86400 ≈ 4.381×10⁻⁸ m³/s, the standard unit in US water-utility regulation and residential water-well pump sizing. The US national average residential water use is about 80-100 gpd per person; a reverse-osmosis membrane module is rated in gpd (50-100 gpd for domestic units). 1 US gpd ≈ 4.381×10⁻⁸ m³/s.
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.
