Convert Cubic metres per day to Acre-feet per day
Convert Cubic metres per day (m³/d) to Acre-feet per day (ac-ft/d) instantly and accurately.
Conversion Formula
ac-ft/d = m³/d × 0.0008107131938
About Cubic metres per day
The cubic metre per day (m³/d) equals 1/86400 ≈ 1.157×10⁻⁵ m³/s, standard in water-resource management, desalination-plant capacity, and per-capita water-consumption accounting. A municipal desalination plant may produce 100 000-1 000 000 m³/d; the WHO minimum water supply requirement is 0.05 m³/d per person. 1 m³/d ≈ 1.157×10⁻⁵ m³/s = 264.2 US gal/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.
