How to Convert MLD to Acre-foot per Day
- 1 MLD = 0.8107131938 acre-ft/day
- 1 acre-ft/day = 1.233481838 MLD
- Example: convert 15 MLD to acre-ft/day: 15 MLD = 15 × 0.8107131938 acre-ft/day = 12.16069791 acre-ft/day
Formula
acre-ft/day = MLD × 0.8107131937899
or acre-ft/day = MLD ÷ 1.233481837548
Derivation from SI units:
- 1 MLD = 10⁶ L/day = 1000 m³/day = 1000/86,400 m³/s.
- 1 acre-ft/day = 1233.48 m³ ÷ 86,400 s; 1 cusec for one day ≈ 1.98 acre-feet.
- 1 MLD = 0.01157407407407 m³/s ÷ 0.0142764101568 m³/s per acre-ft/day = 0.8107131937899 acre-ft/day
Both units are defined exactly, so the factor is exact. MLD definition: million litres per day; Acre-foot per Day definition: acre-foot per day.
Worked examples
- A reading of 20 MLD converts to 16.21426388 acre-ft/day.
20 MLD × 0.8107131938 = 16.21426388 acre-ft/day - A value of 135 MLD is 109.4462812 acre-ft/day.
135 MLD × 0.8107131938 = 109.4462812 acre-ft/day
