About US quarts per hour
The US quart per hour (qt/h) equals 3.785411784×10⁻³/4/3600 ≈ 2.629×10⁻⁷ m³/s, used in US agricultural irrigation drippers (emitters rated in qt/h) and hobby aquaculture systems. A drip emitter rated 1 qt/h ≈ 0.946 L/h is a common size for garden irrigation in the US market. 1 US qt/h ≈ 2.629×10⁻⁷ 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.
