Mount Everest (Tibetan: Chomolungma or Qomolangma “Holy Mother”; Nepali: सगरमाथा, Sagarmāthā) is the world’s highest mountain, with a peak at 8,848 meters (29,029 ft) above sea level. It is located in the Mahalangur section of the Himalayas. The international boundary runs across the precise summit point. Its massif includes neighboring peaks Lhotse (8516 m), Nuptse (7855 m) and Changtse (7580 m).
In 1856, the Great Trigonometric Survey of British India established the first published height of Everest, then known as Peak XV, at 29,002 ft (8,840 m). In 1865, Everest was given its official English name by the Royal Geographical Society upon a recommendation by Andrew Waugh, the British Surveyor General of India. Waugh named the mountain after his predecessor in the post, Sir George Everest. Although Tibetans had called Everest “Chomolungma” for centuries, Waugh was unaware of this because Nepal and Tibet were closed to foreigners.
