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.

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.
