µL/min = gpm × 4546090
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 minute
The microlitre per minute (µL/min) equals 10⁻⁹/60 ≈ 1.667×10⁻¹¹ m³/s, standard in nano-HPLC chromatography and microfluidic chip pumping. A typical nano-LC column runs at 200-400 µL/min; piezoelectric micro-dosing systems for pharmaceutical assays dispense at 1-50 µL/min. 1 µL/min = 1/60 µL/s ≈ 1.667×10⁻¹¹ m³/s.
