About UK pints per hour
The UK pint per hour (pt/h) equals 4.54609×10⁻³/8/3600 ≈ 1.578×10⁻⁷ m³/s, used in British slow-infusion clinical records and historical dairy milk-flow measurements before metrication. An IV drip set at 100 mL/h equals ≈176 UK fl oz/h ≈ 8.8 UK pt/h. 1 UK pt/h ≈ 1.578×10⁻⁷ 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.
