Conversion Formula
µL/min = gph × 63090.1964
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 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.
