Cubic feet per day (ft³/d)
Acre-feet per minute (ac-ft/min)

Conversion Formula

ac-ft/min = ft³/d × 1.594225079e-8

About Cubic feet per day

The cubic foot per day (ft³/d) equals 0.028316846592/86400 ≈ 3.277×10⁻⁷ m³/s, found in US oil-and-gas production reports for low-rate gas wells and groundwater monitoring wells. A marginal coalbed-methane well producing 50 Mcf/d (50 000 ft³/d) of gas represents a modest but economic flow; residential water-well yield tests report in ft³/d. 1 ft³/d ≈ 3.277×10⁻⁷ m³/s.

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.
