Convert Acre-feet per hour to US gallons per minute
Convert Acre-feet per hour (ac-ft/h) to US gallons per minute (gpm) instantly and accurately.
Conversion Formula
gpm = ac-ft/h × 5430.857143
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.
About US gallons per minute
The US gallon per minute (gpm) equals 3.785411784×10⁻³/60 ≈ 6.309×10⁻⁵ m³/s, the dominant volumetric flow unit in US plumbing, HVAC, and water-treatment industries. EPA showerhead standards are set at 2.5 gpm; residential water meters size at 3/4"-1" for 5-20 gpm; municipal water-distribution design uses hundreds to thousands of gpm. 1 gpm ≈ 6.309×10⁻⁵ m³/s = 3.785 L/min.
