Convert Cubic metres per second to Cubic metres per hour
Convert Cubic metres per second (m³/s) to Cubic metres per hour (m³/h) instantly and accurately.
Conversion Formula
m³/h = m³/s × 3600
About Cubic metres per second
The cubic metre per second (m³/s) is the SI coherent unit of volumetric flow rate. It is used for large river discharges, turbine inlet flows, and major pipeline capacities. The Amazon River at its mouth averages ≈200 000 m³/s; a large hydroelectric turbine passes 400-800 m³/s; a major municipal water-main carries 5-20 m³/s. 1 m³/s = 1 000 L/s ≈ 15 850 US gal/min = 35.315 ft³/s.
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.
