Standing 13,803 ft (4,207 m) above sea level, its peak is the highest point in the U.S. state of Hawaii. However, much of Mauna Kea is below sea level; when measured from its oceanic base, its height is 33,100 ft (10,100 m)—more than twice Mount Everest's base-to-peak height of 11,980 to 15,260 ft (3,650 to 4,650 m).
