The total volume of water in the world’s oceans is estimated to be around 1.332 billion cubic kilometers (km³). This staggering figure represents about 97% of all the water on Earth.
To put that into perspective, if you were to fill a cube with each side measuring approximately 1,080 kilometers (or about 670 miles), it would contain the same amount of water as all the oceans combined. The vastness of the oceans not only plays a crucial role in regulating the Earth’s climate but also serves as home to an incredible diversity of marine life.
It’s fascinating to think about such a large volume — it’s hard to visualize, but consider that this water supports all the ecosystems on our planet and is vital for our survival!
