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.

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.
