Convert Acre-feet per Day to Cumecs (acre-ft/day to m3/s)
1 acre-foot per day (acre-ft/day) = 0.01427641016 cumecs (m³/s). 1 m³/s = 70.04561994 acre-ft/day. Example: 15 acre-ft/day = 15 × 0.01427641016 = 0.2141461524 m³/s.

How to Convert Acre-foot per Day to Cumec
- 1 acre-ft/day = 0.01427641016 m³/s
- 1 m³/s = 70.04561994 acre-ft/day
- Example: convert 15 acre-ft/day to m³/s: 15 acre-ft/day = 15 × 0.01427641016 m³/s = 0.2141461524 m³/s
Formula
m³/s = acre-ft/day × 0.0142764101568
or m³/s = acre-ft/day ÷ 70.04561994345
Derivation from SI units:
- 1 acre-ft/day = 1233.48 m³ ÷ 86,400 s; 1 cusec for one day ≈ 1.98 acre-feet.
- 1 cumec = 1 m³/s.
Both units are defined exactly, so the factor is exact. Acre-foot per Day definition: acre-foot per day; Cumec definition: cumec.
Worked examples
- A reading of 10 acre-ft/day converts to 0.1427641016 m³/s.
10 acre-ft/day × 0.01427641016 = 0.1427641016 m³/s - A value of 500 acre-ft/day is 7.138205078 m³/s.
500 acre-ft/day × 0.01427641016 = 7.138205078 m³/s

Frequently asked questions
How many cumecs are in 1 acre-foot per day?
1 acre-ft/day = 0.01427641016 m³/s.
How do I convert acre-feet per day to cumecs?
Multiply the value in acre-ft/day by 0.01427641016, or divide it by 70.04561994. For example, 15 acre-ft/day × 0.01427641016 = 0.2141461524 m³/s.
Is the acre-ft/day to m³/s conversion exact?
Yes. Both units are defined exactly, so the ratio is exact; its decimal form does not terminate and is shown here to 10 significant figures (more with the precision selector).
