Convert Acre-feet per second to US gallons per second
Convert Acre-feet per second (ac-ft/s) to US gallons per second (gal/s) instantly and accurately.
Conversion Formula
gal/s = ac-ft/s × 325851.4286
About Acre-feet per second
The acre-foot per second (ac-ft/s) equals 1233.48183754752 m³/s, an enormous unit representing the flow that would fill a football-field-sized area to 1 ft depth every second. It appears in descriptions of exceptionally large dam-break flood waves and major river-system extreme events. The 1976 Teton Dam collapse peak outflow was estimated at ≈65 000 ft³/s ≈ 1.49 ac-ft/s. 1 ac-ft/s = 1 233.48 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.
