If all of Earth’s water (oceans, icecaps and glaciers, lakes, rivers, ground water, and water in the atmosphere) was put into a sphere, then the diameter of that water ball would be about 860 miles (about 1,385 kilometers) across, a bit more than the distance between Salt Lake City, Utah to Topeka, Kansas. The volume of all water would be about 332.5 million cubic miles (mi3), or 1,386 million cubic kilometers (km3). The picture at the top of this page illustrates this. A cubic mile of water equals more than 1.1 trillion gallons. A cubic kilometer of water equals about 264 billion gallons.
Less than you thought?
