About US fluid ounces per second
The US fluid ounce per second (fl oz/s) equals 3.785411784×10⁻³/128 ≈ 2.957×10⁻⁵ m³/s. It appears in US food-processing and beverage-filling machine specifications, where high-speed bottling lines may fill containers at dozens of fluid ounces per second per nozzle. A standard 16 fl oz bottle filled in 0.5 s corresponds to 32 fl oz/s per lane. 1 fl oz/s ≈ 2.957×10⁻⁵ m³/s.
About US gallons per day

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.
