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 Kilolitres per hour
The kilolitre per hour (kL/h) equals 1/3600 m³/s ≈ 2.778×10⁻⁴ m³/s, identical to m³/h. It is used interchangeably with m³/h in Australian, New Zealand, and South African process-engineering practice. Pump datasheets from these markets quote capacity in kL/h; water-meter billing in rural areas uses kL/h for irrigation allocation. 1 kL/h = 1 m³/h = 1 000 L/h.
