Question

How many gallons of water are in the ocean?

Answer 1

There is an estimated 1.4 billion cubic kilometres of water on the planet, of which 97.4% (1.36 billion km^3) is salt water. To put that in more familiar units, that's 359,000,000,000,000,000,000 (359 quintillion) US gallons or 1,360,000,000,000,000,000,000 (1.36 sextillion) litres.

There is a very striking visual representation of the amount of water on Earth, a computer-generated rendering of what it would look like if all the water on Earth were gathered into a ball - it's the left image of the two linked here -
