Convert US gallons per hour to US quarts per minute
Convert US gallons per hour (gph) to US quarts per minute (qt/min) instantly and accurately.
Conversion Formula
qt/min = gph × 0.06666666667
About US gallons per hour
The US gallon per hour (gph) equals 3.785411784×10⁻³/3600 ≈ 1.051×10⁻⁶ m³/s, common in oil-burner nozzle ratings, water-softener regeneration, and RV/marine-plumbing specifications. Residential oil-burner nozzles are rated in gph (e.g., 0.75 gph, 1.00 gph); a small boat bilge pump might handle 200-500 gph. 1 US gph ≈ 1.052×10⁻⁶ m³/s ≈ 3.785 L/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.
