A little more than the previous measurement of Nepal and about four meters higher than that of China: this is the new agreement on the altitude of Everest: 8,848.86 meters .
In 1856, the Great Trigonometric Topography Project established the first published altitude of Everest, then known as Peak XV, at 8,840 meters . China and Nepal reached a consensus last year on the joint announcement of the new peak height, and it is being made public now.
Everest height conflict
In 2005, China again measured the altitude of the mountain and obtained a result of 8844.43 meters. Thus began a discussion between China and Nepal that lasted five years. China argued that the measurement should be done up to the altitude of the rock, which is 8,844 meters, but Nepal objected that it should be done up to the altitude of the snow, which is 8,848 meters .

In 2010, both nations agreed that the altitude of the mountain is 8,848 meters, and Nepal acknowledged China’s claim that the altitude to the rock of Everest is 8,844 meters. Now, in 2020, both countries have closed the matter with a commonly recognized height.
However, we must not confuse the highest point on Earth with the highest mountain in the world. This mountain is Mauna Kea , it is the Hawaiian Islands, which is 10,205 meters from its underwater base in the Hawaiian depression to its summit. Of this total height, 4,205 meters are above sea level.
