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 Litres per day

The litre per day (L/d) equals 10⁻³/86400 ≈ 1.157×10⁻⁸ m³/s, standard in water-resource management, reverse-osmosis membrane rating, and daily per-capita water-use statistics. A residential reverse-osmosis unit produces 100-300 L/d of purified water; the WHO minimum for basic household use is 50 L/d per person. 1 L/d ≈ 1.157×10⁻⁸ m³/s.
