Convert Megalitres per day to Cubic feet per second
Convert Megalitres per day (ML/d) to Cubic feet per second (ft³/s) instantly and accurately.
Conversion Formula
ft³/s = ML/d × 0.4087345685
About Megalitres per day
The megalitre per day (ML/d) equals 1000/86400 ≈ 0.011574 m³/s, numerically identical to million litres per day. It is the preferred notation in Australian water-authority reporting, environmental flow assessments, and reservoir storage accounting. Murray-Darling Basin environmental flows are specified in ML/d; urban water utilities publish reservoir capacity and daily draw in ML/d. 1 ML/d ≈ 0.011574 m³/s = 1 000 m³/d.
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.
