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.
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.
