About US gallons per minute
The US gallon per minute (gpm) equals 3.785411784×10⁻³/60 ≈ 6.309×10⁻⁵ m³/s, the dominant volumetric flow unit in US plumbing, HVAC, and water-treatment industries. EPA showerhead standards are set at 2.5 gpm; residential water meters size at 3/4"-1" for 5-20 gpm; municipal water-distribution design uses hundreds to thousands of gpm. 1 gpm ≈ 6.309×10⁻⁵ m³/s = 3.785 L/min.
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.
