Convert Microlitres per hour (µL/h) to US gallons per hour (gph) instantly and accurately.

Microlitres per hour (µL/h)
US gallons per hour (gph)

Conversion Formula

gph = µL/h × 2.641720524e-7

About Microlitres per hour

The microlitre per hour (µL/h) equals 10⁻⁹/3600 ≈ 2.778×10⁻¹³ m³/s, used in implantable drug-delivery pumps and osmotic mini-pumps for controlled-release pharmacokinetic studies. An Alzet osmotic pump for rodent experiments delivers 0.25-10 µL/h of dissolved drug directly into tissue. 1 µL/h ≈ 2.778×10⁻¹³ m³/s.

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.
