Convert US pints per hour to Acre-feet per day
Convert US pints per hour (pt/h) to Acre-feet per day (ac-ft/d) instantly and accurately.
Conversion Formula
ac-ft/d = pt/h × 9.206649832e-6
About US pints per hour
The US pint per hour (pt/h) equals 3.785411784×10⁻³/8/3600 ≈ 1.314×10⁻⁷ m³/s, used in US medical-device standards for slow-drip infusion and in American homebrew calculations for sparge water addition rates. A slow gravity sparge at 24 pt/h = 3 US gal/h is typical for small-batch homebrewing. 1 US pt/h ≈ 1.314×10⁻⁷ m³/s.
About Acre-feet per day
The acre-foot per day (ac-ft/d) equals 1233.48183754752/86400 ≈ 0.014278 m³/s, the practical unit for daily water-delivery scheduling in western US irrigation districts and river-compact administration. Water rights in the Colorado River system are specified in acre-feet per year; daily delivery schedules convert to ac-ft/d. A moderate-size irrigation lateral delivers 5-50 ac-ft/d. 1 ac-ft/d ≈ 0.014278 m³/s ≈ 504.2 US gal/min.
