Convert US quarts per minute to UK gallons per hour
Convert US quarts per minute (qt/min) to UK gallons per hour (gph) instantly and accurately.
Conversion Formula
gph = qt/min × 12.49011277
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.
About UK gallons per hour
The UK gallon per hour (gph) equals 4.54609×10⁻³/3600 ≈ 1.263×10⁻⁶ m³/s, found in pre-metric British burner-nozzle ratings, oil-consumption logs for diesel generators, and ship fuel-economy records. British aviation fuel consumption was once published in UK gal/h; legacy Lloyd's Register tanker descriptions used UK gal/h for cargo pump capacities. 1 UK gph ≈ 1.263×10⁻⁶ m³/s.
