Convert Cubic feet per second to Cubic metres per hour
Convert Cubic feet per second (ft³/s) to Cubic metres per hour (m³/h) instantly and accurately.
Conversion Formula
m³/h = ft³/s × 101.9406477
About Cubic feet per second
The cubic foot per second (ft³/s or cfs) equals 0.028316846592 m³/s, the primary unit for measuring river discharge and open-channel flow in the United States. The US Geological Survey publishes all streamflow data in cfs; irrigation water rights, flood-control gates, and dam spillway capacities are specified in cfs. The Colorado River at full natural flow is ≈22 000 cfs. 1 cfs = 0.028316846592 m³/s ≈ 28.317 L/s ≈ 448.8 US gpm.
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.
