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 Acre-feet per minute

The acre-foot per minute (ac-ft/min) equals 1233.48183754752/60 ≈ 20.558 m³/s, encountered in large irrigation canal capacity descriptions and reservoir emergency spillway sizing in the US West. A major canal gate releasing 1 ac-ft/min drains a 1-acre field 1 foot deep every minute - a substantial agricultural flow. 1 ac-ft/min ≈ 20.558 m³/s ≈ 726.0 ft³/s.
