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 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.
