How to Convert Acre-foot per Day to MGD (imperial)
- 1 acre-ft/day = 0.2713280726 MGD (imp)
- 1 MGD (imp) = 3.685575143 acre-ft/day
- Example: convert 15 acre-ft/day to MGD (imp): 15 acre-ft/day = 15 × 0.2713280726 MGD (imp) = 4.069921089 MGD (imp)
Formula
MGD (imp) = acre-ft/day × 0.2713280725959
or MGD (imp) = acre-ft/day ÷ 3.685575143156
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 (imp) = 10⁶ × 4.54609 L per day ≈ 0.0526 m³/s.
- 1 acre-ft/day = 0.0142764101568 m³/s ÷ 0.05261678240741 m³/s per MGD (imp) = 0.2713280725959 MGD (imp)
Both units are defined exactly, so the factor is exact. Acre-foot per Day definition: acre-foot per day; MGD (imperial) definition: million imperial gallons per day.
Worked examples
- A reading of 10 acre-ft/day converts to 2.713280726 MGD (imp).
10 acre-ft/day × 0.2713280726 = 2.713280726 MGD (imp) - A value of 500 acre-ft/day is 135.6640363 MGD (imp).
500 acre-ft/day × 0.2713280726 = 135.6640363 MGD (imp)
