About UK gallons per second
The UK (imperial) gallon per second (gal/s) equals 4.54609×10⁻³ m³/s, about 20% larger than the US gallon per second. It appears in pre-metric British fire-fighting standards, large pump test certificates, and naval engineering calculations. A UK fire engine pump rated 1 000 UK gal/min delivers ≈16.67 UK gal/s. 1 UK gal/s = 4.54609×10⁻³ m³/s ≈ 1.201 US gal/s.
About Cubic metres per day
The cubic metre per day (m³/d) equals 1/86400 ≈ 1.157×10⁻⁵ m³/s, standard in water-resource management, desalination-plant capacity, and per-capita water-consumption accounting. A municipal desalination plant may produce 100 000-1 000 000 m³/d; the WHO minimum water supply requirement is 0.05 m³/d per person. 1 m³/d ≈ 1.157×10⁻⁵ m³/s = 264.2 US gal/d.
