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 Millilitres per hour
The millilitre per hour (mL/h) equals 10⁻⁶/3600 ≈ 2.778×10⁻¹⁰ m³/s, standard for intravenous infusion pumps in clinical medicine and for slow-release laboratory syringe pumps. A 1 L IV bag running over 8 hours is set to 125 mL/h; subcutaneous insulin pumps deliver 1-100 mL/h of dilute insulin. 1 mL/h ≈ 2.778×10⁻¹⁰ m³/s.
