How to Convert Acre-foot per Day to MGD
- 1 acre-ft/day = 0.3258514286 MGD
- 1 MGD = 3.068883277 acre-ft/day
- Example: convert 15 acre-ft/day to MGD: 15 acre-ft/day = 15 × 0.3258514286 MGD = 4.887771429 MGD
Formula
MGD = acre-ft/day × 0.3258514285714
or MGD = acre-ft/day ÷ 3.068883277217
Derivation from SI units:
- 1 acre-ft/day = 1233.48 m³ ÷ 86,400 s; 1 cusec for one day ≈ 1.98 acre-feet.
- 1 MGD = 10⁶ × 3.785411784 L per day ≈ 0.0438 m³/s.
- 1 acre-ft/day = 0.0142764101568 m³/s ÷ 0.04381263638889 m³/s per MGD = 0.3258514285714 MGD
Both units are defined exactly, so the factor is exact. Acre-foot per Day definition: acre-foot per day; MGD definition: million US gallons per day.
Worked examples
- A reading of 10 acre-ft/day converts to 3.258514286 MGD.
10 acre-ft/day × 0.3258514286 = 3.258514286 MGD - A value of 500 acre-ft/day is 162.9257143 MGD.
500 acre-ft/day × 0.3258514286 = 162.9257143 MGD
