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 Kilolitres per day

The kilolitre per day (kL/d) equals 1/86400 ≈ 1.157×10⁻⁵ m³/s, the standard unit for per-household and per-property water-consumption billing in Australia. Sydney Water and other Australian utilities charge tariffs per kL/d consumed; a typical Australian household uses 0.6-1.0 kL/d. 1 kL/d = 1 m³/d ≈ 264.2 US gal/d.
