After years of painstaking work, surveyors from Nepal and China have announced that Mount Everest is exactly 29,032 feet (or 8,848.86 meters) tall. This new measurement means the world’s tallest mountain

The new measurement means Everest is exactly 2.82 feet higher above sea level than the previous, widely accepted official height. That measurement, announced in an Indian survey, had stood since the yearly ’50s.
To take the measurements, the surveyors deployed both traditional and cutting-edge approaches. They performed a standard land survey, which utilizes trigonometric measurements. And they also took measurements via satellite. Additionally the surveyors brought in a gravimeter to determine where exactly sea level lies beneath Everest. (A gravimeter is an instrument that measures the force of gravity in a given spot on Earth.)
Prior to this endeavor, there’d been disagreement between Nepal and China as to how to measure Everest. As
Everest’s height above sea level, however, is fluid. Thanks to opposing forces between shifting tectonic plates, and earthquakes, Everest bobs up and down. Butting tectonic plates push the mountain up, and the earthquakes bring it back down. But moving forward, China and Nepal will, hopefully, at least continue to agree on
