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.

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.
