About UK gallons per minute
The UK (imperial) gallon per minute (gpm) equals 4.54609×10⁻³/60 ≈ 7.577×10⁻⁵ m³/s, historically used in British plumbing design, pump curves, and water-treatment plant sizing. Pre-metric UK water-industry capacity tables and pump manufacturers quoted flows in UK gal/min; legacy British Standard BS EN pump curves often show both units. 1 UK gpm ≈ 7.577×10⁻⁵ m³/s ≈ 4.546 L/min.
About Cubic yards per second
The cubic yard per second (yd³/s) equals 0.764554857984 m³/s, a large unit used in US civil engineering for river flood-stage measurements and reservoir emergency-spillway capacity. A major dam spillway releasing water at 1 000 yd³/s could drain an Olympic pool in about 3 seconds. 1 yd³/s = 0.764554857984 m³/s ≈ 764.555 L/s ≈ 27 ft³/s.
