About UK fluid ounces per minute

The UK fluid ounce per minute (fl oz/min) equals 4.54609×10⁻³/160/60 ≈ 4.735×10⁻⁷ m³/s. It is found in pre-metric British plumbing and brewing specifications, where tap-flow and pump-delivery rates were stated in imperial fluid ounces per minute. A UK laboratory peristaltic pump calibrated to 30 fl oz/min delivers ≈14.2 mL/s. 1 UK fl oz/min ≈ 4.735×10⁻⁷ 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.
