What Is This Tool?
This online converter allows users to transform volume measurements from the unit acre-foot (US survey) to gigaliter [GL]. It serves to facilitate understanding and communication of large water volumes by converting smaller scale acre-foot units into larger, more manageable gigaliter values.
How to Use This Tool?
-
Enter the volume in acre-foot (US survey) in the input field.
-
Select the target unit as gigaliter [GL].
-
Hit the convert button to obtain the equivalent value in gigaliters.
Key Features
-
Converts volume from acre-foot (US survey) to gigaliter (GL).
-
Browser-based and easy to use without software installation.
-
Supports water resource management and hydrological applications.
Examples
-
10 acre-feet (US survey) converts to approximately 0.012334892 GL.
-
100 acre-feet (US survey) converts to approximately 0.12334892 GL.
Common Use Cases
-
Measuring and managing water volumes stored in reservoirs and dams.
-
Allocating irrigation water rights and reporting deliveries in agriculture.
-
Planning municipal or regional water supplies using aggregated volume data.
Tips & Best Practices
-
Confirm usage of US survey foot measurement when working with acre-foot numbers.
-
Use gigaliter units for large-scale water volumes to simplify data presentation.
-
Verify consistency of volume definitions across datasets for accurate conversions.
Limitations
-
Acre-foot (US survey) may differ slightly from units based on metric or international feet.
-
Gigaliter is not ideal for small or local water volume calculations.
-
Conversion accuracy depends on precise definitions of US survey foot and consistent measurement standards.
Frequently Asked Questions
-
Why is acre-foot (US survey) used for volume measurements?
-
Acre-foot (US survey) represents the volume of water covering one acre to a depth of one US survey foot, commonly used in water management and irrigation contexts.
-
What applications require conversion to gigaliters?
-
Gigaliters are suited for quantifying very large water volumes such as reservoir capacities, large-scale resource planning, and industrial water reporting.
-
Are there any differences between US survey foot and international foot measurements?
-
Yes, acre-foot (US survey) uses US survey feet which may slightly vary from international or metric foot-based volumes, affecting precise conversions.
Key Terminology
-
Acre-foot (US survey)
-
A volume unit defined as water covering one acre to a depth of one US survey foot, equal to 43,560 cubic US survey feet.
-
Gigaliter (GL)
-
A unit of volume equal to one billion liters or one million cubic meters, used for measuring very large volumes of liquids.
-
US survey foot
-
A foot measurement standard used in the United States survey system, differing slightly from the international foot.
