Conversion Formula

kL/h = L/s × 3.6

About Litres per second

The litre per second (L/s) equals 10⁻³ m³/s, the standard unit for municipal water-supply engineering, fire-fighting flows, and HVAC system air handling. A fire hydrant delivers 15-30 L/s; a household mains water connection is typically 0.1-0.5 L/s; a large building HVAC chilled-water loop circulates 50-200 L/s. 1 L/s = 10⁻³ m³/s = 3.6 m³/h ≈ 15.85 US gal/min.

About Kilolitres per hour

The kilolitre per hour (kL/h) equals 1/3600 m³/s ≈ 2.778×10⁻⁴ m³/s, identical to m³/h. It is used interchangeably with m³/h in Australian, New Zealand, and South African process-engineering practice. Pump datasheets from these markets quote capacity in kL/h; water-meter billing in rural areas uses kL/h for irrigation allocation. 1 kL/h = 1 m³/h = 1 000 L/h.
