How much water is there in the world’s oceans?

The world’s oceans take up 71% of the Earth’s surface. The pacific is the largest, accounting for 46% of the water surface on Earth, followed by the Atlantic at 29% and the Indian Ocean at 20%.

But how much water is there?!

Well, the total volume of water in the Earth’s Oceans totals up to a staggering 1.332 billion cubic kilometres! That’s over 532 Quadrillion (532,800,000,000,000,000) Olympic sized swimming pools worth of water. A pretty huge number to say the least.

We can make that huge number a little bit smaller by splitting up into each ocean which comes in at;

Ocean Amount of water
Pacific 707.5 million km3
Atlantic 323 million km3
Indian 284 million km3
