Final answer:
Mount Everest is the world's tallest mountain at 8,848.86 meters (29,031.7 feet) located on the China-Nepal border. Its height in kilometers is approximately 8.849, calculated by dividing its height in feet by the conversion factor of 3,281 feet per kilometer.
Step-by-step explanation:
Mount Everest, known for being the tallest mountain in the world, has a current official height of 8,848.86 meters (29,031.7 feet) after a revision in 2020. Resting on the border between China and Nepal in the Himalayan range, this majestic peak continues to attract climbers and researchers alike.
To convert the height of Mount Everest from feet to kilometers, since 1 kilometer equals 3,281 feet, we divide 29,028 feet by 3,281 feet per kilometer, resulting in approximately 8.849 kilometers. This measurement is symbolic of Earth's dynamic nature, evidenced by fossils of marine limestone at Everest's summit dating back to the Ordovician period, indicating that this area was once beneath the sea.
