The short answer: K2 is estimated to weigh approximately 1.2 trillion kilograms (about 2.6 trillion lb), based on its massive volume and rock density. The figure is a rough estimate.
K2 weight by type
K2, on the China-Pakistan border, is the second-highest mountain on Earth at 8,611 m (28,251 ft). Its estimated weight is derived from its enormous volume and the density of its rock.
| Aspect | Approximate figure |
|---|---|
| Summit height | 8,611 m (28,251 ft) |
| Rank by height | second-highest on Earth |
| Estimated mass | around 1.2 trillion kg |
| Primary material | rock, with snow and ice cover |
| Confidence level | rough order-of-magnitude estimate |
What affects K2 weight
- Volume. K2's great height and steep bulk set the amount of rock involved.
- Rock density. The density of its rock determines mass per cubic meter.
- Base definition. Where the base is drawn changes the volume counted.
- Steep shape. K2's pyramid-like form affects how much material it holds.
- Snow and ice. Permanent glaciers and ice add some weight.
- Estimation method. The figure is approximate, based on geometry and density.
How K2 weight compares
K2's mass is so immense that no everyday object compares; it far exceeds the combined weight of all the world's tallest skyscrapers put together.
Frequently asked questions
How much does K2 weigh?
K2 is estimated to weigh approximately 1.2 trillion kilograms. The figure is a rough estimate from its volume and rock density.
Why is K2's weight only an estimate?
Mountains have irregular shapes and no clear lower boundary, so the volume and resulting weight can only be approximated, not measured directly.
Is K2 heavier than Mount Everest?
No. Everest is both taller and more massive, with a weight estimated in the hundreds of trillions of kilograms, far more than K2.
