How tall is Mount Everest?

Mount Everest, also known as Sagarmatha by Nepalese, Chomolungma, (Pinyin) Zhumulangma Feng or (Wade-Giles romanization) Chu-mu-lang-ma Feng by Tibetans and Chinese, is a Mountainous summit. Sir George Everest, English surveyors chief of India from 1830 to 1843, was christened the summit in 1865, and it was formerly known as Peak XV. It is a part of the Himalayan mountains in southern Asia, located at 27°59′ N 86°56′ E on the demarcation line between Nepal and the People's Republic of China, Mt. Everest is the tallest peak on the planet, rising to a height of 29,032 feet (8,849 m).
Everest, like other big mountains in the vicinity, has always remained cherished by locals. Chomolungma, the most often used Tibetan name, means "Goddess Mother of the World" or "Goddess of the Valley." The Sanskrit term Sagarmatha roughly translates to "Heaven's Mountain." It was not acknowledged as the highest altitude on the Planet's terrain until 1852 when the Indian administration's Survey of India confirmed it.

Indian estimates

Due to fluctuations in ice cover, gravitational departure, and sunlight scattering, there was debate over the actual altitude of the peak. The Government of India determined the value 29,028 feet (8,848 meters) more or less a proportion around 1952 and 1954, and it remained popularly recognized. Until 1999, most academics, geospatial organizations, and publications utilized this number.

Chinese and Italian surveys

Following then, efforts were undertaken to re-measure the mountain's elevation. A Chinese study in 1975 reported a measurement of 29,029.24 feet (8,848.11 meters), and an Italian assessment in 1987 reported a measurement of 29,108 feet (8,872 meters) using orbital charting technologies, however, concerns emerged regarding the methodology employed. Another Italian study in 1992, utilizing the Global Navigation Satellite (GPS) and laser measuring techniques, obtained the number 29,023 feet (8,846 meters) by removing 6.5 feet (2 meters) of heavy frost on the peak from the reported elevation, although the technique was brought into doubt once more.

The United States and National Geographic Society estimates

In 1999, a study funded by the National Geographic Association and partners in the United States used GPS technology to take exact assessments. The organization and other experts in the domains of geodetic and mapping recognized their result of 29,035 feet (8,850 meters) plus or minus 6.5 feet (2 meters).

2005 Chinese assessment

In 2005, the Chinese launched a new mission that combined ice-penetrating sonar with GPS technology. The outcome was a "rock height" of 29,017.12 feet (8,844.43 meters) that, while being extensively publicized in the press, was solely acknowledged by China for the following many years. Nepal, for instance, contested the Chinese measurement, choosing 29,028 feet as the "frost altitude." China and Nepal decided in April 2010 to accept the legitimacy of both estimates.

Recent analysis and reported elevation

China and Nepal officially reported Everest's elevation to be 29,031.69 feet in December 2020 (8,848.86 meters). This revised estimate was acknowledged by numerous experts in the domains of geodetic and mapping, particularly the National Geographic Society, and was obtained from information from assessments conducted by Nepal in 2019 and China in 2020 using Satellite and Geostationary navigational technologies and infrared leveling.
