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 US fluid ounces per second

The US fluid ounce per second (fl oz/s) equals 3.785411784×10⁻³/128 ≈ 2.957×10⁻⁵ m³/s. It appears in US food-processing and beverage-filling machine specifications, where high-speed bottling lines may fill containers at dozens of fluid ounces per second per nozzle. A standard 16 fl oz bottle filled in 0.5 s corresponds to 32 fl oz/s per lane. 1 fl oz/s ≈ 2.957×10⁻⁵ m³/s.
