Volumetric flow rate converter

Rivers are gauged in cubic metres per second, or cubic feet per second ('cusecs') in the US: the Thames at London averages 65 m³/s, the Rhine at Cologne about 2,000, the Amazon over 200,000. Pumps and taps are rated in litres per minute or US gallons per minute (a garden hose gives 10–20 l/min, a shower about 9), water utilities count megalitres per day, and oil wells barrels per day. 1 m³/s is 1,000 l/s or 35.3 cfs.
