Convert Microlitres per hour to UK gallons per minute
Convert Microlitres per hour (µL/h) to UK gallons per minute (gpm) instantly and accurately.
Conversion Formula
gpm = µL/h × 3.666154138e-9
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 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.
