Everest is about 5.1 million quarter-thicknesses high.

Count Everest's summit elevation in the thickness of a U.S. quarter and you get about 5.1 million.

This uses the quarter's specified 1.75 mm thickness as a measuring stick. It isn't a claim that a real stack of five million circulated coins would stand up straight or measure perfectly.
