Convert US gallons per hour to Cubic metres per day
Convert US gallons per hour (gph) to Cubic metres per day (m³/d) instantly and accurately.
Conversion Formula
m³/d = gph × 0.09084988282
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 Cubic metres per day
The cubic metre per day (m³/d) equals 1/86400 ≈ 1.157×10⁻⁵ m³/s, standard in water-resource management, desalination-plant capacity, and per-capita water-consumption accounting. A municipal desalination plant may produce 100 000-1 000 000 m³/d; the WHO minimum water supply requirement is 0.05 m³/d per person. 1 m³/d ≈ 1.157×10⁻⁵ m³/s = 264.2 US gal/d.
