The Pacific Ocean Covers ~28% of Earth’s Surface

The Pacific Ocean spans approximately 165.2 million km² (64.2 million mi²), covering about 28% of the Earth’s total surface area. It stretches from the Arctic to the Southern Ocean and from Asia‑Australia to the Americas, making it the largest and deepest ocean basin.

Its vastness influences global climate, weather patterns (El Niño/La Niña), and marine biodiversity.
