About UK gallons per minute
The UK (imperial) gallon per minute (gpm) equals 4.54609×10⁻³/60 ≈ 7.577×10⁻⁵ m³/s, historically used in British plumbing design, pump curves, and water-treatment plant sizing. Pre-metric UK water-industry capacity tables and pump manufacturers quoted flows in UK gal/min; legacy British Standard BS EN pump curves often show both units. 1 UK gpm ≈ 7.577×10⁻⁵ m³/s ≈ 4.546 L/min.
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.
