About Cubic foot per second (ft³/s)
An imperial flow-rate unit used predominantly in US hydrology, river-discharge measurement, water-resource engineering, and large-scale waterworks design. Also called "cfs" or the colloquial "cusec" in US water-resources jargon. The US Geological Survey (USGS) StreamStats and the National Water Information System publish all US river streamgage data in cfs — a federal reporting standard since the 1950s. US Army Corps of Engineers flood-routing analyses, FEMA flood-insurance studies, and state water-rights records (especially in the western US under prior-appropriation doctrine) all measure discharge in cfs. Reference values: a small headwater stream might flow 5-20 cfs at base flow and 200-500 cfs during a 100-year storm; the Colorado River below Glen Canyon Dam is typically 8,000-25,000 cfs; the lower Mississippi runs 350,000-600,000 cfs depending on the season. 1 ft³/s = 7.4805 US gallons per second = 449 GPM = 28.32 L/s = 0.02832 m³/s.
About Cubic meter per hour (m³/hr)
A metric flow-rate unit equal to exactly 1/3,600 m³/s. m³/hr is the de-facto standard unit for industrial process flows in metric countries, HVAC air handling (DIN EN 16798 / ASHRAE 62.1 ventilation calcs), pump sizing in European pump curves (KSB, Grundfos, Wilo specifications), natural-gas metering and the gas grid balance reports (TSO data is in Mm³/hr), municipal water-treatment plant capacity, and biogas/anaerobic-digester output. European building-code minimum air-exchange rates (e.g., German DIN 1946 fresh-air requirements per occupant) and Eurovent-certified fan-coil ratings are almost always expressed in m³/hr. Practical reference: a typical residential heat-recovery ventilation unit moves 100-400 m³/hr; an industrial centrifugal pump might be rated at 50-5,000 m³/hr. Convert to GPM by multiplying by 4.403, to CFM by multiplying by 0.5886, to L/s by dividing by 3.6.
