About US fluid ounces per minute
The US fluid ounce per minute (fl oz/min) equals 3.785411784×10⁻³/128/60 ≈ 4.929×10⁻⁷ m³/s. It is found in US consumer-product flow specifications such as showerhead flow ratings, beverage dispenser settings, and fuel-injector bench tests in US automotive workshops. A showerhead rated at 48 fl oz/min delivers exactly 1.5 US gal/min. 1 fl oz/min ≈ 4.929×10⁻⁷ m³/s.
About UK gallons per minute
The UK (imperial) gallon per minute (gpm) equals 4.54609×10⁻³/60 ≈ 7.577×10⁻⁵ m³/s, historically used in British plumbing design, pump curves, and water-treatment plant sizing. Pre-metric UK water-industry capacity tables and pump manufacturers quoted flows in UK gal/min; legacy British Standard BS EN pump curves often show both units. 1 UK gpm ≈ 7.577×10⁻⁵ m³/s ≈ 4.546 L/min.
