Convert Cubic metres per hour to Kilolitres per second
Convert Cubic metres per hour (m³/h) to Kilolitres per second (kL/s) instantly and accurately.
Conversion Formula
kL/s = m³/h × 0.0002777777778
About Cubic metres per hour
The cubic metre per hour (m³/h) equals 1/3600 m³/s ≈ 2.778×10⁻⁴ m³/s, the dominant volumetric flow unit in European process engineering, HVAC, and water treatment. Pump datasheet curves, heat-exchanger sizing software, and wastewater-treatment design all use m³/h as the standard. A domestic water pump runs at 3-8 m³/h; a municipal WWTP inlet pump handles 500-5 000 m³/h. 1 m³/h ≈ 2.778×10⁻⁴ m³/s = 1 000 L/h.
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.
