Convert Cubic metres per day to US gallons per minute
Convert Cubic metres per day (m³/d) to US gallons per minute (gpm) instantly and accurately.
Conversion Formula
gpm = m³/d × 0.1834528141
About Cubic metres per day
The cubic metre per day (m³/d) equals 1/86400 ≈ 1.157×10⁻⁵ m³/s, standard in water-resource management, desalination-plant capacity, and per-capita water-consumption accounting. A municipal desalination plant may produce 100 000-1 000 000 m³/d; the WHO minimum water supply requirement is 0.05 m³/d per person. 1 m³/d ≈ 1.157×10⁻⁵ m³/s = 264.2 US gal/d.
About US gallons per minute
The US gallon per minute (gpm) equals 3.785411784×10⁻³/60 ≈ 6.309×10⁻⁵ m³/s, the dominant volumetric flow unit in US plumbing, HVAC, and water-treatment industries. EPA showerhead standards are set at 2.5 gpm; residential water meters size at 3/4"-1" for 5-20 gpm; municipal water-distribution design uses hundreds to thousands of gpm. 1 gpm ≈ 6.309×10⁻⁵ m³/s = 3.785 L/min.
