Convert Millilitres per hour to US gallons per day
Convert Millilitres per hour (mL/h) to US gallons per day (gpd) instantly and accurately.
Conversion Formula
gpd = mL/h × 0.006340129257
About Millilitres per hour
The millilitre per hour (mL/h) equals 10⁻⁶/3600 ≈ 2.778×10⁻¹⁰ m³/s, standard for intravenous infusion pumps in clinical medicine and for slow-release laboratory syringe pumps. A 1 L IV bag running over 8 hours is set to 125 mL/h; subcutaneous insulin pumps deliver 1-100 mL/h of dilute insulin. 1 mL/h ≈ 2.778×10⁻¹⁰ m³/s.
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.
