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 UK fluid ounces per hour

The UK fluid ounce per hour (fl oz/h) equals 4.54609×10⁻³/160/3600 ≈ 7.892×10⁻⁹ m³/s, used in low-flow British clinical settings and historical laboratory records. IV fluid delivery rates in old UK nursing charts and slow-drip infusion protocols were documented in fl oz/h before metrication. 1 UK fl oz/h ≈ 7.892×10⁻⁹ m³/s.
