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 minute

The litre per minute (L/min) equals 10⁻³/60 ≈ 1.667×10⁻⁵ m³/s, one of the most common flow units in consumer and light-industrial applications. Household washing machines use 10-15 L/min; oxygen concentrators deliver 1-10 L/min to patients; a standard garden sprinkler head discharges 15-30 L/min. 1 L/min ≈ 1.667×10⁻⁵ m³/s ≈ 0.2642 US gal/min.
