How to Convert Acre-foot per Day to MLD
- 1 acre-ft/day = 1.233481838 MLD
- 1 MLD = 0.8107131938 acre-ft/day
- Example: convert 15 acre-ft/day to MLD: 15 acre-ft/day = 15 × 1.233481838 MLD = 18.50222756 MLD
Formula
MLD = acre-ft/day × 1.233481837548
Derivation from SI units:
- 1 acre-ft/day = 1233.48 m³ ÷ 86,400 s; 1 cusec for one day ≈ 1.98 acre-feet.
- 1 MLD = 10⁶ L/day = 1000 m³/day = 1000/86,400 m³/s.
- 1 acre-ft/day = 0.0142764101568 m³/s ÷ 0.01157407407407 m³/s per MLD = 1.233481837548 MLD
Both units are defined exactly, so the factor is exact. Acre-foot per Day definition: acre-foot per day; MLD definition: million litres per day.
Worked examples
- A reading of 10 acre-ft/day converts to 12.33481838 MLD.
10 acre-ft/day × 1.233481838 = 12.33481838 MLD - A value of 500 acre-ft/day is 616.7409188 MLD.
500 acre-ft/day × 1.233481838 = 616.7409188 MLD
