If the glaciers in the ice cap that covers Greenland were spread across the entire globe, how deep would the ice be?

Greenland's ice sheet contains approximately 2.85 million cubic kilometers of ice. When spread across Earth's total surface area of about 510 million square kilometers, this creates a layer approximately 5.6 meters or 17-18 feet deep. This calculation demonstrates the enormous volume of freshwater stored in Greenland's glaciers and their potential impact if melted.
