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 UK fluid ounces per second
The UK (imperial) fluid ounce per second (fl oz/s) equals 4.54609×10⁻³/160 ≈ 2.841×10⁻⁵ m³/s, slightly larger than its US counterpart. It appears in pre-metric British food-manufacturing and brewing standards. A traditional UK draught-beer tap dispenses 1 pint (20 fl oz) in about 2 seconds, equating to ≈10 UK fl oz/s. 1 UK fl oz/s ≈ 2.841×10⁻⁵ m³/s ≈ 0.9608 US fl oz/s.
