Mount Everest: China and Nepal agree on new, taller height

Countries have settled on 8,848.86m - higher than either's previous measurements

Mount Everest is marginally higher than previously thought, according to a new joint Chinese-Nepalese calculation that settles a long-running conflict over the height of the world's tallest peak, which straddles the countries' shared border.

Kathmandu and Beijing had differed over its exact height, but after each sent an expedition of surveyors to the summit they have agreed that the official height is 8,848.86 metres (29,032ft), a bit more than their previous calculations.
