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 Kilolitres per second

The kilolitre per second (kL/s) equals 1 m³/s, so 1 kL/s is identical to 1 m³/s. The term kilolitre is favoured in Australian and South African engineering over the equivalent cubic metre per second. Municipal water-main flow and stormwater-channel capacity are sometimes expressed in kL/s in these countries. 1 kL/s = 1 m³/s = 1 000 L/s ≈ 15 850 US gal/min.
