Convert US gallons per hour to Millilitres per second
Convert US gallons per hour (gph) to Millilitres per second (mL/s) instantly and accurately.
Conversion Formula
mL/s = gph × 1.051503273
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 Millilitres per second
The millilitre per second (mL/s) equals 10⁻⁶ m³/s, common in laboratory syringe pumps, HPLC systems, and medical infusion devices. A standard IV drip running at 1 mL/s would deliver 3.6 L/h - a rapid infusion rate used in resuscitation; analytical HPLC columns run 0.5-5 mL/s. 1 mL/s = 10⁻⁶ m³/s = 60 mL/min = 3.6 L/h.
