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 Cubic inches per second
The cubic inch per second (in³/s) equals 1.6387064×10⁻⁵ m³/s, used in US automotive engineering for engine displacement sweep rate, fuel-injector calibration, and hydraulic actuator speed specifications. An engine injector delivering 15 in³/s of fuel corresponds to roughly 15.5 mL/s; hydraulic jacks in US equipment are rated in in³/s at operating pressure. 1 in³/s ≈ 1.639×10⁻⁵ m³/s = 0.016387 L/s.
