What Is This Tool?
This converter transforms volume values measured in cubic foot (ft^3), commonly used in engineering and trade, into acre-foot (US survey), a unit essential for water resource management. It simplifies converting large volumes of water into units suitable for hydrology, irrigation, and municipal planning.
How to Use This Tool?
-
Enter the volume in cubic foot (ft^3) you want to convert
-
Select the target unit as acre-foot (US survey)
-
Click the convert button to get the result instantly
Key Features
-
Converts volume from cubic foot to acre-foot (US survey)
-
Supports calculations relevant to water resource and agricultural management
-
Browser-based and easy to use with clear input and output
-
Provides conversion aligned with US customary and survey foot standards
Examples
-
500 cubic feet = 0.01147835 acre-foot (US survey)
-
10,000 cubic feet = 0.229567 acre-foot (US survey)
Common Use Cases
-
Measuring water volumes in reservoirs and dams
-
Allocating and reporting irrigation water deliveries
-
Planning municipal or regional annual water supply
-
Estimating natural gas volumes or storage spaces (using cubic foot)
Tips & Best Practices
-
Ensure consistent use of US survey foot definitions when converting
-
Use acre-foot (US survey) for large water volume measurements rather than small-scale estimates
-
Double-check input values for accurate calculations especially in water resource applications
Limitations
-
Conversion assumes US survey foot and differs from other international foot definitions
-
Acre-foot unit is impractical for measuring small volumes
-
Accurate results rely on correct application of US customary volume units
Frequently Asked Questions
-
What is a cubic foot used for?
-
A cubic foot measures volume in US customary and imperial systems, used in engineering, trade, HVAC design, and material quantity estimation.
-
Why convert cubic feet to acre-foot (US survey)?
-
Converting to acre-foot helps quantify large water volumes for management of reservoirs, irrigation allocation, and municipal water supply planning.
-
Does the conversion factor vary internationally?
-
Yes, because this conversion specifically uses US survey foot standards, the factor may differ slightly from international definitions.
Key Terminology
-
Cubic foot [ft^3]
-
A volume unit defined as the space of a cube with one-foot sides, used in US customary and imperial systems.
-
Acre-foot (US survey)
-
A volume unit representing water covering one acre to a depth of one US survey foot, equal to 43,560 cubic US survey feet.
-
US survey foot
-
A foot measurement standard used predominantly in US surveying, differing slightly from the international foot.
