Convert Acre-feet per Day to Cusecs (acre-ft/day to ft3/s)
1 acre-foot per day (acre-ft/day) = 0.5041666667 cusecs (ft³/s). 1 ft³/s = 1.983471074 acre-ft/day. Example: 15 acre-ft/day = 15 × 0.5041666667 = 7.5625 ft³/s.

How to Convert Acre-foot per Day to Cusec
- 1 acre-ft/day = 0.5041666667 ft³/s
- 1 ft³/s = 1.983471074 acre-ft/day
- Example: convert 15 acre-ft/day to ft³/s: 15 acre-ft/day = 15 × 0.5041666667 ft³/s = 7.5625 ft³/s
Formula
ft³/s = acre-ft/day × 0.5041666666667
or ft³/s = acre-ft/day ÷ 1.98347107438
Derivation from SI units:
- 1 acre-ft/day = 1233.48 m³ ÷ 86,400 s; 1 cusec for one day ≈ 1.98 acre-feet.
- 1 cusec = 1 ft³/s = 0.028316846592 m³/s.
- 1 acre-ft/day = 0.0142764101568 m³/s ÷ 0.028316846592 m³/s per ft³/s = 0.5041666666667 ft³/s
Both units are defined exactly, so the factor is exact. Acre-foot per Day definition: acre-foot per day; Cusec definition: cusec.
Worked examples
- A reading of 10 acre-ft/day converts to 5.041666667 ft³/s.
10 acre-ft/day × 0.5041666667 = 5.041666667 ft³/s - A value of 500 acre-ft/day is 252.0833333 ft³/s.
500 acre-ft/day × 0.5041666667 = 252.0833333 ft³/s
