About UK gallons per hour

The UK gallon per hour (gph) equals 4.54609×10⁻³/3600 ≈ 1.263×10⁻⁶ m³/s, found in pre-metric British burner-nozzle ratings, oil-consumption logs for diesel generators, and ship fuel-economy records. British aviation fuel consumption was once published in UK gal/h; legacy Lloyd's Register tanker descriptions used UK gal/h for cargo pump capacities. 1 UK gph ≈ 1.263×10⁻⁶ m³/s.

About Million litres per day

The million litres per day (ML/d or MLD) equals 1000/86400 ≈ 0.011574 m³/s, the standard capacity unit for water-treatment plants, sewage-treatment works, and desalination facilities in the UK, India, and much of the Commonwealth. A small town water-treatment works processes 5-20 ML/d; the Beckton Sewage Treatment Works in London treats ≈700 ML/d. 1 ML/d ≈ 0.011574 m³/s = 1 000 m³/d.
