About UK fluid ounces per minute
The UK fluid ounce per minute (fl oz/min) equals 4.54609×10⁻³/160/60 ≈ 4.735×10⁻⁷ m³/s. It is found in pre-metric British plumbing and brewing specifications, where tap-flow and pump-delivery rates were stated in imperial fluid ounces per minute. A UK laboratory peristaltic pump calibrated to 30 fl oz/min delivers ≈14.2 mL/s. 1 UK fl oz/min ≈ 4.735×10⁻⁷ m³/s.
About US gallons per hour
The US gallon per hour (gph) equals 3.785411784×10⁻³/3600 ≈ 1.051×10⁻⁶ m³/s, common in oil-burner nozzle ratings, water-softener regeneration, and RV/marine-plumbing specifications. Residential oil-burner nozzles are rated in gph (e.g., 0.75 gph, 1.00 gph); a small boat bilge pump might handle 200-500 gph. 1 US gph ≈ 1.052×10⁻⁶ m³/s ≈ 3.785 L/h.
