Acre-Foot [ac·ft]

The acre-foot is a unit of volume commonly used in the United States to measure large quantities of water, especially in agriculture and water resource management.

One acre-foot equals the volume of water that would cover one acre of land to a depth of one foot.

Earth's Volume

The volume of Earth is approximately:

1.08321 × 10¹² km³

or

1,083,210,000,000 cubic kilometers

This value is based on Earth being roughly a sphere (though it's slightly flattened at the poles), with an average radius of about 6,371 kilometers. The formula used to calculate the volume of a sphere is:

Substituting Earth's average radius:

This immense volume gives Earth enough space to hold all of its oceans, atmosphere, and solid mass. It's a key figure in geophysics, helping scientists understand Earth's mass distribution, density, and structure.
