what is the present height of mount everest
Mount Everest On 9 October 2005, after several months of measurement and calculation, the Chinese Academy of Sciences and State Bureau of Surveying and Mapping officially announced the height of Everest as 8,844.43 m (29,017.16 ft) with accuracy of ±0.21 m (8.3 in). They claimed it was the most accurate and precise measurement to date.[36] This height is based on the highest point of rock and not the snow and ice covering it. The Chinese team also measured a snow-ice depth of 3.5 m (11 ft),[32] which is in agreement with a net elevation of 8,848 m (29,029 ft). The snow and ice thickness varies over time, making a definitive height of the snow cap impossible to determine.
Edmund Hillary Tenzing later wrote that Hillary took the first step onto the summit and he followed. They reached Everest's 29,028 ft (8,848 m) summit – the highest point on earth – at 11:30 am.[1][33]
