KATHMANDU, Nepal — Mount Everest is the tallest mountain in the world, but precisely how tall is it?
It’s not such a simple question.
In the past, geologists have disagreed about what to include in their calculations: Should the summit’s snowcap be included? Or should surveyors drill down to the peak’s rock base?
What about the recent earthquakes in Nepal, which geologists believe shrunk the mountain by about three centimeters, or a little more than an inch? Or the fact that wind speed affects how much snow covers the summit at any given time?
Then there is the challenge of geography: Reaching the summit of Everest is only possible a few weeks each year, and measuring the mountain’s height from sea level has presented difficulties in the past. (Landlocked Nepal is a long way from the nearest shore.)
Today, Everest’s height is widely recognized as 29,029 feet

But teams from around the world, including China, Denmark, Italy, India and the United States, have come up with other calculations, which have sometimes strayed a little bit higher, or a little bit lower, than that figure. Italy, in 1992, lopped seven feet off the standard height, measuring it at 29,022 feet. In 1999, a measurement by American scientists pushed the peak a little higher, saying the mountain reached 29,035 feet./NYT
