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.

About US quarts per minute

The US quart per minute (qt/min) equals 3.785411784×10⁻³/4/60 ≈ 1.577×10⁻⁵ m³/s, encountered in US small-engine fuel system testing and food-processing pump calibration. Engine dynamometer fuel-flow instrumentation sometimes uses qt/min when testing small gasoline engines consuming 1-6 qt/min at full load. 1 US qt/min ≈ 1.577×10⁻⁵ m³/s.
