About US fluid ounces per minute

The US fluid ounce per minute (fl oz/min) equals 3.785411784×10⁻³/128/60 ≈ 4.929×10⁻⁷ m³/s. It is found in US consumer-product flow specifications such as showerhead flow ratings, beverage dispenser settings, and fuel-injector bench tests in US automotive workshops. A showerhead rated at 48 fl oz/min delivers exactly 1.5 US gal/min. 1 fl oz/min ≈ 4.929×10⁻⁷ m³/s.

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.
