About UK fluid ounces per hour

The UK fluid ounce per hour (fl oz/h) equals 4.54609×10⁻³/160/3600 ≈ 7.892×10⁻⁹ m³/s, used in low-flow British clinical settings and historical laboratory records. IV fluid delivery rates in old UK nursing charts and slow-drip infusion protocols were documented in fl oz/h before metrication. 1 UK fl oz/h ≈ 7.892×10⁻⁹ 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.
