About Litres per day
The litre per day (L/d) equals 10⁻³/86400 ≈ 1.157×10⁻⁸ m³/s, standard in water-resource management, reverse-osmosis membrane rating, and daily per-capita water-use statistics. A residential reverse-osmosis unit produces 100-300 L/d of purified water; the WHO minimum for basic household use is 50 L/d per person. 1 L/d ≈ 1.157×10⁻⁸ m³/s.
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.
