Mount Everest, known in Nepal as Sagarmāthā and in Tibet as Chomolungma, is World Highest Peak above sea level, located in the Mahalangur Himal sub-range of the Himalayas . The international border between China and Nepal runs across its summit point.
The current official elevation of 8,848 m (29,029 ft), recognised by China and Nepal, was established by a 1955 Indian survey and subsequently confirmed by a Chinese survey in 1975.In 2005, China remeasured the rock height of the mountain, with a result of 8844.43 m. There followed an argument between China and Nepal as to whether the official height should be the rock height (8,844 m., China) or the snow height (8,848 m., Nepal). In 2010, an agreement was reached by both sides that the height of Everest is 8,848 m, and Nepal recognises China's claim that the rock height of Everest is 8,844 m.
In 1865, Everest was given its official English name by theRoyal Geographical Society, upon a recommendation by Andrew Wauge , the BritishSurveyor General of India. As there appeared to be several different local names, Waugh chose to name the mountain after his predecessor in the post,Sir George Everest , despite George Everest's objections.
