How the floor count compares

The Burj Khalifa passed Chicago's Sears Tower, now Willis Tower, for the most floors of any building in February 2007, while still under construction, according to Wikipedia. For scale, the Empire State Building in New York has 102 stories. Going up all those floors is quick: the tower has 57 elevators, and the double-deck cars travel at up to 10 m/s. Free Tours by Foot says the elevator reaches level 124 in about one minute. Our guide to the elevators explains how they work.
