What Is This Tool?
This unit converter assists in changing volumetric flow measurements from acre-foot per year, a volume covering one acre to a depth of one foot delivered annually, into cubic meters per day, representing daily volume flow. It's ideal for water resource planning, municipal supply, and irrigation management.
How to Use This Tool?
-
Enter the flow rate value in acre-foot per year.
-
Select acre-foot/year as the input unit and cubic meter/day as the output unit.
-
Click the convert button to get the equivalent daily flow volume in cubic meters.
-
Use the results for planning, reporting, or operational purposes.

Examples
-
Convert 2 acre-foot/year to cubic meter/day: 2 × 3.3794158123 = 6.7588316246 m^3/d
-
Convert 0.5 acre-foot/year to cubic meter/day: 0.5 × 3.3794158123 = 1.68970790615 m^3/d
Common Use Cases
-
Water resource management and reservoir release rate assessment
-
Allocating irrigation water rights in agricultural areas
-
Municipal or regional water supply and demand forecasting
-
Monitoring daily volumes for water treatment plants
-
Industrial process flow rates or hydrocarbon production volumes
Tips & Best Practices
-
Ensure the flow is consistently averaged over the year for accurate daily conversion.
-
Use this conversion for planning and reporting rather than exact instantaneous flow rates.
-
Consider calendar year variations or leap years separately if precision timing is essential.
-
Double-check unit selections to prevent errors during conversion.
Limitations
-
Assumes uniform flow distribution over the entire year, which may not match actual conditions.
-
Does not account for calendar year length differences or leap years.
-
Conversion is a simple factor and may not capture flow variability in real time.
Frequently Asked Questions
-
What does acre-foot/year represent?
-
It is the volume that covers one acre of land to a depth of one foot delivered over one year, commonly used for long-term water flow measurements.
-
Why convert acre-foot/year to cubic meter/day?
-
This helps translate annual water volumes into daily flow rates for municipal supply, operational, or reporting needs.
-
Is the conversion factor exact for all cases?
-
The conversion uses a fixed rate assuming uniform flow, so it might not represent variable or intermittent flows accurately.
Key Terminology
-
Acre-foot/year [ac*ft/y]
-
A flow rate defined as one acre-foot of volume delivered or used over a year; one acre-foot is volume covering one acre to a depth of one foot.
-
Cubic meter/day [m^3/d]
-
A flow rate indicating one cubic meter of fluid passing or consumed each day, representing daily volumetric flow.
