What is the official elevation of Mount Everest, rounded to the nearest metre?

The official elevation of Mount Everest, rounded to the nearest metre, is 8,849 metres.

Nepal and China announced the jointly measured height in 2020 as 8,848.86 metres above sea level. Rounding that figure to the nearest metre gives 8,849 metres. The measurement includes the snow and ice cap covering the summit, an important detail when comparing different surveys.

Everest stands in the Mahalangur Himal sub-range of the Himalayas, on the border between Nepal and Tibet, an autonomous region of China. In Nepal it is called Sagarmatha, while in Tibet it is known as Chomolungma.

Older references commonly give 8,848 metres because earlier surveys produced slightly different results. Earthquakes, tectonic uplift, snow conditions, and measurement methods all help explain why published figures have changed over time.
