About UK gallons per hour

The UK gallon per hour (gph) equals 4.54609×10⁻³/3600 ≈ 1.263×10⁻⁶ m³/s, found in pre-metric British burner-nozzle ratings, oil-consumption logs for diesel generators, and ship fuel-economy records. British aviation fuel consumption was once published in UK gal/h; legacy Lloyd's Register tanker descriptions used UK gal/h for cargo pump capacities. 1 UK gph ≈ 1.263×10⁻⁶ m³/s.

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.
