Mount Everest – also called Sagarmāthā (Nepali: सगरमाथा), Chomolungma or Qomolangma (Tibetan: ཇོ་མོ་གླང་མ) or Zhumulangma (Chinese: 珠穆朗玛峰 Zhūmùlǎngmǎ Fēng) – is the highest mountain on Earth, and the highest point on the Earth’s crust, as measured by the height above sea level of its summit, 8,848 metres (29,029 ft). The mountain, which is part of the Himalaya range in Asia, is located on the border between Sagarmatha Zone, Nepal, and Tibet, China.
In 1856, the Great Trigonometric Survey of 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 recommendation of Andrew Waugh, the British Surveyor General of India at the time. Chomolungma had been in common use by Tibetans for centuries, but Waugh was unable to propose an established local name because Nepal and Tibet were closed to foreigners.
