Combined answer

Mount Everest is the tallest mountain in the world by elevation above sea level. It lies in the Himalayas on the Nepal–China (Tibet) border.

Height: Reported figures differ slightly. They include about 8,848 m (29,029 ft), 8,848.86 m (29,031.7 ft), and 8,849 m (29,032 ft). The differences come from different survey dates and rounding. The 8,848.86 m figure comes from the 2020 joint survey by China and Nepal. Check an official source if you need an exact figure.

Other ways to measure "tallest":

  • Base to peak: Mauna Kea in Hawaii rises about 10,200 m (33,500 ft) from the ocean floor. Only about 4,207 m (13,803 ft) of that is above sea level.
  • Farthest from Earth's center: Chimborazo in Ecuador has the summit farthest from the center of the Earth. This is because of the planet's equatorial bulge.

Everest is the standard answer to "tallest mountain in the world."

The models agreed closely enough to produce one combined answer.
