Convert Acre-feet per minute to Cubic feet per second

Convert Acre-feet per minute (ac-ft/min) to Cubic feet per second (ft³/s) instantly and accurately.

Acre-feet per minute (ac-ft/min)
Cubic feet per second (ft³/s)

Conversion Formula

ft³/s = ac-ft/min × 726

About Acre-feet per minute

The acre-foot per minute (ac-ft/min) equals 1233.48183754752/60 ≈ 20.558 m³/s, encountered in large irrigation canal capacity descriptions and reservoir emergency spillway sizing in the US West. A major canal gate releasing 1 ac-ft/min drains a 1-acre field 1 foot deep every minute - a substantial agricultural flow. 1 ac-ft/min ≈ 20.558 m³/s ≈ 726.0 ft³/s.

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.
