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 Cubic inches per second
The cubic inch per second (in³/s) equals 1.6387064×10⁻⁵ m³/s, used in US automotive engineering for engine displacement sweep rate, fuel-injector calibration, and hydraulic actuator speed specifications. An engine injector delivering 15 in³/s of fuel corresponds to roughly 15.5 mL/s; hydraulic jacks in US equipment are rated in in³/s at operating pressure. 1 in³/s ≈ 1.639×10⁻⁵ m³/s = 0.016387 L/s.
