About Litres per hour

The litre per hour (L/h) equals 10⁻³/3600 ≈ 2.778×10⁻⁷ m³/s, widely used in automotive fuel consumption (L/h), irrigation drip systems, and small pump specifications. A fuel cell vehicle running on hydrogen consumes ±2 L/h of liquid equivalent; a domestic water softener regeneration cycle uses 40-100 L/h of brine. 1 L/h ≈ 2.778×10⁻⁷ m³/s ≈ 0.2642 US gal/h.

About US quarts per minute

The US quart per minute (qt/min) equals 3.785411784×10⁻³/4/60 ≈ 1.577×10⁻⁵ m³/s, encountered in US small-engine fuel system testing and food-processing pump calibration. Engine dynamometer fuel-flow instrumentation sometimes uses qt/min when testing small gasoline engines consuming 1-6 qt/min at full load. 1 US qt/min ≈ 1.577×10⁻⁵ m³/s.
