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 Litres per day

The litre per day (L/d) equals 10⁻³/86400 ≈ 1.157×10⁻⁸ m³/s, standard in water-resource management, reverse-osmosis membrane rating, and daily per-capita water-use statistics. A residential reverse-osmosis unit produces 100-300 L/d of purified water; the WHO minimum for basic household use is 50 L/d per person. 1 L/d ≈ 1.157×10⁻⁸ m³/s.
