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.
About Litres per minute
The litre per minute (L/min) equals 10⁻³/60 ≈ 1.667×10⁻⁵ m³/s, one of the most common flow units in consumer and light-industrial applications. Household washing machines use 10-15 L/min; oxygen concentrators deliver 1-10 L/min to patients; a standard garden sprinkler head discharges 15-30 L/min. 1 L/min ≈ 1.667×10⁻⁵ m³/s ≈ 0.2642 US gal/min.
