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 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.
