Litres per Second to Acre-feet per Day (L/s to acre-ft/day)
1 litre per second (L/s) = 0.07004561994 acre-feet per day (acre-ft/day). 1 acre-ft/day = 14.27641016 L/s. Example: 15 L/s = 15 × 0.07004561994 = 1.050684299 acre-ft/day.

How to Convert Litre per Second to Acre-foot per Day
- 1 L/s = 0.07004561994 acre-ft/day
- 1 acre-ft/day = 14.27641016 L/s
- Example: convert 15 L/s to acre-ft/day: 15 L/s = 15 × 0.07004561994 acre-ft/day = 1.050684299 acre-ft/day
Formula
acre-ft/day = L/s × 0.07004561994345
or acre-ft/day = L/s ÷ 14.2764101568
Derivation from SI units:
- 1 L/s = 10⁻³ m³/s.
- 1 acre-ft/day = 1233.48 m³ ÷ 86,400 s; 1 cusec for one day ≈ 1.98 acre-feet.
- 1 L/s = 0.001 m³/s ÷ 0.0142764101568 m³/s per acre-ft/day = 0.07004561994345 acre-ft/day
Both units are defined exactly, so the factor is exact. Litre per Second definition: litre per second; Acre-foot per Day definition: acre-foot per day.
Worked examples
- A reading of 5 L/s converts to 0.3502280997 acre-ft/day.
5 L/s × 0.07004561994 = 0.3502280997 acre-ft/day - A value of 50 L/s is 3.502280997 acre-ft/day.
50 L/s × 0.07004561994 = 3.502280997 acre-ft/day

Where it's used
Litres per Second are used for tube-well and pump discharge, while acre-feet per day appear in US irrigation district deliveries. Both measure volumetric discharge of rivers, canals and water supply, so the conversion is a fixed factor.

Frequently asked questions
How many acre-feet per day are in 1 litre per second?
1 L/s = 0.07004561994 acre-ft/day.
How do I convert litres per second to acre-feet per day?
Multiply the value in L/s by 0.07004561994, or divide it by 14.27641016. For example, 15 L/s × 0.07004561994 = 1.050684299 acre-ft/day.
Is the L/s to acre-ft/day 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).
