Conversion Formula
m³/min = gpd × 2.628758183e-6
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 Cubic metres per minute
The cubic metre per minute (m³/min) equals 1/60 m³/s ≈ 1.667×10⁻² m³/s, used in large compressor and blower specifications, tunnel ventilation design, and industrial air-handling. A mine-ventilation fan may move 1 000-5 000 m³/min; an industrial rotary-screw compressor delivers 5-50 m³/min of free air. 1 m³/min = 1 000 L/min ≈ 35.31 ft³/min ≈ 264.2 US gal/min.
