What Is This Tool?
This tool converts volumetric flow rates measured in gallons (US) per day to acre-feet per year, enabling comparisons between small-scale daily flows and large-scale annual water volumes.
How to Use This Tool?
-
Enter the flow rate value in gallon (US) per day
-
Select gallon (US)/day as the input unit
-
Choose acre-foot/year as the output unit
-
Click convert to see the equivalent flow rate
Key Features
-
Converts between gallon (US)/day and acre-foot/year units accurately
-
Useful for water resource management and agricultural planning
-
Supports simple input of values with instant conversion results
-
Browser-based and easy to use without installation
Examples
-
10 gal (US)/d converts to 0.011201379 ac*ft/y
-
50 gal (US)/d converts to 0.056006895 ac*ft/y
Common Use Cases
-
Reporting household or per capita daily water consumption
-
Evaluating small well or groundwater yields in pumping tests
-
Chemical dosing and leak rate specifications in water treatment
-
Planning water resource allocation and reservoir release rates
-
Accounting for municipal or regional water supply demands
Tips & Best Practices
-
Ensure flow rates are relatively stable when using this conversion
-
Use gallons per day for smaller flow measurements and acre-feet per year for larger volumes
-
Confirm unit appropriateness depending on the scale of water flow
-
Apply this conversion to compare daily water usage to annual planning metrics
Limitations
-
Assumes constant flow rates over time and may not apply to highly variable flows
-
Not suitable for very short-term measurements or fluctuating conditions
-
Gallons per day measure small-scale flows whereas acre-feet per year measure large volumes; direct use depends on context
Frequently Asked Questions
-
What does 1 gallon (US)/day represent?
-
It is a volumetric flow rate equal to one US liquid gallon of volume passing a point in one day.
-
Why convert gallon (US)/day to acre-foot/year?
-
Converting helps relate small daily water flows to larger annual water volumes for resource planning and management.
-
When should I not use this conversion?
-
Avoid using this conversion for highly variable or very short-term flow measurements as it assumes steady rates.
Key Terminology
-
gallon (US)/day [gal (US)/d]
-
A unit of volumetric flow rate indicating one US liquid gallon passing a point per day.
-
acre-foot/year [ac*ft/y]
-
A flow rate equal to one acre-foot volume delivered or used over one year, representing a volume of water covering one acre to a depth of one foot.
