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 gallons per hour
The UK gallon per hour (gph) equals 4.54609×10⁻³/3600 ≈ 1.263×10⁻⁶ m³/s, found in pre-metric British burner-nozzle ratings, oil-consumption logs for diesel generators, and ship fuel-economy records. British aviation fuel consumption was once published in UK gal/h; legacy Lloyd's Register tanker descriptions used UK gal/h for cargo pump capacities. 1 UK gph ≈ 1.263×10⁻⁶ m³/s.
