What is the official elevation of Mount Everest established by Nepal and China in 2020?

The official elevation of Mount Everest established by Nepal and China in 2020 is 8,848.86 metres.

Nepal and China announced the jointly measured height on 8 December 2020. The figure includes the mountain’s snow and ice cap, which can change over time because of snowfall, erosion and earthquakes.

Everest stands in the Himalayas on the border between Nepal and Tibet, an autonomous region of China. Nepal commonly calls the mountain Sagarmatha, while Tibetans call it Chomolungma. The English name honours George Everest, a former Surveyor General of India.

Earlier official measurements differed slightly. India’s 1954 survey produced a height of 8,848 metres, while later surveys used different methods and reference points. The 2020 figure is the jointly accepted modern elevation.
