What is a cubic kilometer?

A cubic kilometer is an SI-derived unit representing the volume of a cube with each side of 1 kilometer, equal to 1 billion cubic meters or 1 trillion liters.

What defines the US gallon unit?

The US gallon is defined as exactly 231 cubic inches, equivalent to 3.785411784 liters, and is used mainly in the United States for liquid volume measurements.

Why convert cubic kilometers to US gallons?

This conversion helps express extremely large volumes in more familiar and smaller units used predominantly in the US, aiding in resource planning and environmental communication.
