Convert Megalitres per day to Acre-feet per day
Convert Megalitres per day (ML/d) to Acre-feet per day (ac-ft/d) instantly and accurately.
Conversion Formula
ac-ft/d = ML/d × 0.8107131938
About Megalitres per day
The megalitre per day (ML/d) equals 1000/86400 ≈ 0.011574 m³/s, numerically identical to million litres per day. It is the preferred notation in Australian water-authority reporting, environmental flow assessments, and reservoir storage accounting. Murray-Darling Basin environmental flows are specified in ML/d; urban water utilities publish reservoir capacity and daily draw in ML/d. 1 ML/d ≈ 0.011574 m³/s = 1 000 m³/d.
About Acre-feet per day
The acre-foot per day (ac-ft/d) equals 1233.48183754752/86400 ≈ 0.014278 m³/s, the practical unit for daily water-delivery scheduling in western US irrigation districts and river-compact administration. Water rights in the Colorado River system are specified in acre-feet per year; daily delivery schedules convert to ac-ft/d. A moderate-size irrigation lateral delivers 5-50 ac-ft/d. 1 ac-ft/d ≈ 0.014278 m³/s ≈ 504.2 US gal/min.
