What is a cubic kilometer used for?

A cubic kilometer measures very large volumes like those of lakes, reservoirs, glaciers, and major engineering projects.

Why use acre-feet instead of cubic kilometers?

Acre-feet are commonly used in water resource management and agriculture to express more practical volumes for water supply and irrigation.

Can this tool be used for non-water volumes?

This conversion is intended for water volumes, as acre-foot is specific to such contexts and may not apply well elsewhere.

What Is This Tool?

This converter transforms large volume measurements from cubic kilometers, a metric unit suitable for enormous volumes like lakes and reservoirs, into acre-feet, a customary unit widely used for managing water supplies and irrigation.

How to Use This Tool?

Enter the volume value in cubic kilometers you want to convert.
Select cubic kilometer [km³] as the source unit.
Choose acre-foot [ac*ft] as the target unit.
Click the convert button to view the result in acre-feet.

Key Features

Converts volume from cubic kilometers to acre-feet accurately using standard rates.
Browser-based tool requiring no installation for convenient access.
Supports large-scale water volume conversions in hydrology and water supply planning.

Examples

1 cubic kilometer equals 810,713.19 acre-feet.
0.5 cubic kilometer converts to 405,356.60 acre-feet.

Common Use Cases

Quantifying large water volumes in lakes, reservoirs, and dams for water planning.
Measuring glacier and ice sheet volumes in environmental studies.
Allocating irrigation water for agricultural management.
Reporting municipal and regional water supply volumes.

Tips & Best Practices

Double-check volume entries for accuracy before converting.
Use the tool for conversions related specifically to water volume applications.
Keep in mind the scale of measurement to avoid rounding errors in critical calculations.

Limitations

High precision work may be affected by rounding errors due to the large measurement scale.
Acre-foot is tailored to water volume contexts and may not suit other types of volume measurements.
