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.

About US fluid ounces per second

The US fluid ounce per second (fl oz/s) equals 3.785411784×10⁻³/128 ≈ 2.957×10⁻⁵ m³/s. It appears in US food-processing and beverage-filling machine specifications, where high-speed bottling lines may fill containers at dozens of fluid ounces per second per nozzle. A standard 16 fl oz bottle filled in 0.5 s corresponds to 32 fl oz/s per lane. 1 fl oz/s ≈ 2.957×10⁻⁵ m³/s.
