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 Litres per minute
The litre per minute (L/min) equals 10⁻³/60 ≈ 1.667×10⁻⁵ m³/s, one of the most common flow units in consumer and light-industrial applications. Household washing machines use 10-15 L/min; oxygen concentrators deliver 1-10 L/min to patients; a standard garden sprinkler head discharges 15-30 L/min. 1 L/min ≈ 1.667×10⁻⁵ m³/s ≈ 0.2642 US gal/min.
