Convert US gallons per day to Microlitres per hour
Convert US gallons per day (gpd) to Microlitres per hour (µL/h) instantly and accurately.
Conversion Formula
µL/h = gpd × 157725.491
About US gallons per day
The US gallon per day (gpd) equals 3.785411784×10⁻³/86400 ≈ 4.381×10⁻⁸ m³/s, the standard unit in US water-utility regulation and residential water-well pump sizing. The US national average residential water use is about 80-100 gpd per person; a reverse-osmosis membrane module is rated in gpd (50-100 gpd for domestic units). 1 US gpd ≈ 4.381×10⁻⁸ m³/s.
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.
