Chinese Mountaineers and researchers from China climbed Mount Everest in May 2005 and concluded that the rock height of the peak was 3.7 meters less than the estimates made in 1954. This means the summit is 8,844.43 meters as opposed to 8848m, which is the height Nepal seems to be sticking to. Another widely quoted height, which takes into account the snow, is that of 8850m, which was recorded in 1999 using Satellite technology.

Officials from China and Nepal who met this week said both heights were accurate.
