About UK gallons per day
The UK gallon per day (gpd) equals 4.54609×10⁻³/86400 ≈ 5.261×10⁻⁸ m³/s, used in British per-capita water-consumption statistics and pre-metric water-authority regulation. Historic UK Water Acts set minimum supply standards in UK gal/d per household; older UK borehole pump test reports quote sustained yield in UK gal/d. 1 UK gpd ≈ 5.261×10⁻⁸ m³/s.
About US fluid ounces per hour
The US fluid ounce per hour (fl oz/h) equals 3.785411784×10⁻³/128/3600 ≈ 8.215×10⁻⁹ m³/s, used in low-flow medical devices and slow-infusion clinical equipment. A nasal cannula oxygen humidifier delivers humidity at 10-50 fl oz/h of water vapour equivalent; micro-dosing chemical feed pumps for water treatment are calibrated in fl oz/h in US systems. 1 fl oz/h ≈ 8.215×10⁻⁹ m³/s.
