Convert UK pints per hour to Acre-feet per hour
Convert UK pints per hour (pt/h) to Acre-feet per hour (ac-ft/h) instantly and accurately.
Conversion Formula
ac-ft/h = pt/h × 4.606968929e-7
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 hour
The acre-foot per hour (ac-ft/h) equals 1233.48183754752/3600 ≈ 0.34263 m³/s, standard for sizing irrigation district delivery canals, reservoir outflow scheduling, and aquifer recharge basin calculations in the western US. The US Bureau of Reclamation uses ac-ft/h for canal operational planning; a 1 000-acre farm irrigating with 0.5 in/h rain-equivalent receives ≈41 ac-ft/h. 1 ac-ft/h ≈ 0.34263 m³/s.
