About These Units
Cubic Foot per Second (CFS)
Cubic feet per second (CFS or cusec) measures river flow, large pumps, and hydraulic systems. Colorado River: 15,000 CFS average. One CFS equals 448.8 GPM, 28.3 L/s, or 7.48 gallons per second. USGS river gauges report in CFS.
Liter per Second (L/s)
Liters per second (L/s) is common for water pumps, fire hoses (15-30 L/s), and plumbing flow rates. One L/s equals 15.85 US GPM or 60 L/min. Fire hydrant minimum flow: 32 L/s. Swimming pool circulation: 5-15 L/s depending on size.
