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 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.
