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 UK fluid ounces per second

The UK (imperial) fluid ounce per second (fl oz/s) equals 4.54609×10⁻³/160 ≈ 2.841×10⁻⁵ m³/s, slightly larger than its US counterpart. It appears in pre-metric British food-manufacturing and brewing standards. A traditional UK draught-beer tap dispenses 1 pint (20 fl oz) in about 2 seconds, equating to ≈10 UK fl oz/s. 1 UK fl oz/s ≈ 2.841×10⁻⁵ m³/s ≈ 0.9608 US fl oz/s.
