This page illustrates the ratio of the total volume of water on Earth compared to the volume of the Earth itself.
The volume of the Earth is calculated using the formula V = 4/3 * π * r³ where r is the radius of the Earth. The Earth's radius is approximately 6,371 kilometers, giving it a volume of about 1.08321 × 1012 cubic kilometers.
The total volume of water on Earth is estimated to be about 1.332 billion cubic kilometers. Comparing these volumes, the water volume constitutes about 0.123% of the Earth's total volume.
