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 second
The US gallon per second (gal/s) equals 3.785411784×10⁻³ m³/s, used for very large pump discharge rates and fire-suppression deluge systems. A large centrifugal fire pump rated 1 500 US gal/min delivers exactly 25 US gal/s; industrial cooling-tower makeup lines are sized in gal/s at peak demand. 1 US gal/s = 3.785411784×10⁻³ m³/s = 60 US gal/min ≈ 227.1 L/min.
