Ice Sheet Volume Calculator — Formule
## Ice Sheet Volume and Sea Level
Ice sheets hold vast quantities of frozen water. If melted, this water raises global sea levels.
### Formula
**Volume (km³) = Area (km²) x Thickness (m) / 1000**
**Water Equivalent = Volume x Ice Density / Water Density**
**Sea Level Rise (m) = Water Equivalent (km³) / Ocean Area (km²) x 10^6**
The Greenland ice sheet contains about 2.85 million km³ of ice, equivalent to roughly 7.2 m of sea level rise.

Exemple Résolu
The Greenland ice sheet has an area of 1,710,000 km² and average thickness of 2,000 m.
- Volume = 1,710,000 x 2,000 / 1,000 = 3,420,000 km³
- Water equivalent = 3,420,000 x 917 / 1,000 = 3,136,140 km³
- Sea level = 3,136,140 / 361,000,000 x 1,000,000 = 8.69 m
- Note: actual Greenland SLE is ~7.2 m due to non-uniform thickness
