Conversion Formula
bbl/s = ft³/s × 0.1781076067
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 US barrels per second
The US barrel per second (bbl/s) equals 0.158987294928 m³/s, an extremely large flow rate used only for catastrophic spill-rate estimates and very large pipeline surge calculations. The 2010 Deepwater Horizon spill peaked at ≈60 000 bbl/d ≈ 0.000694 bbl/s; major subsea pipeline ruptures may briefly exceed 1 bbl/s during decompression. 1 US bbl/s = 0.158987 m³/s ≈ 158.987 L/s.
