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 Microlitres per second

The microlitre per second (µL/s) equals 10⁻⁹ m³/s, the working range of microfluidic lab-on-a-chip devices and nano-HPLC pumps. Organ-on-a-chip perfusion bioreactors, droplet microfluidic systems, and capillary electrophoresis instruments operate at 0.1-100 µL/s. A syringe pump delivering 0.36 mL/h produces exactly 0.1 µL/s. 1 µL/s = 10⁻⁹ m³/s = 60 µL/min.
