Convert US gallons per hour to Microlitres per second
Convert US gallons per hour (gph) to Microlitres per second (µL/s) instantly and accurately.
Conversion Formula
µL/s = gph × 1051.503273
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 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.
