It's about five-and-a-half times as tall as The Statue of Liberty.
In other words, 0.50 kilometers is 5.3770 times the height of The Statue of Liberty, and the height of The Statue of Liberty is 0.1860 times that amount.(a.k.a. "Liberty Enlightening the World," a.k.a. La Liberté Éclairant le Monde) (Liberty Island, New York City, New York) (pedestal base to torch peak)
The Statue of Liberty reaches 0.09299 kilometers including the pedestal. The statue was designed using an optical trick known as "forced perspective" to make the statue appear proportionally correct when viewed from its base and is, in actuality, disproportionately large at the top.
It's about six-and-a-half times as tall as a Giant Sequoia (tree).
In other words, the height of a Giant Sequoia (tree) is 0.150 times 0.50 kilometers.(a.k.a. Sequoiadendron giganteum, a.k.a. Sierra redwood, a.k.a. Wellingtonia)
Giant Sequoias of the Giant Sequoia National Monument located in Sierra Nevada, near Visalia, California can grow to heights of 0.076 kilometers. The wood from the Giant Sequoias is often brittle and prone to shattering when such trees are felled, and as a result the trees logged in the late nineteenth century were often usable only as shingles or matchsticks.
It's about seven-and-a-half times as long as The Wingspan of a 747.
It's about one-tenth as long as The Hollywood Walk of Fame.
In other words, 0.50 kilometers is 0.130 times the length of The Hollywood Walk of Fame, and the length of The Hollywood Walk of Fame is 7.70 times that amount.(Hollywood Boulevard and Vine Street, Hollywood, California) (approximate length)
The Hollywood Walk of Fame is approximately 3.9 km. Gene Autry, most famous as the singer of "Back in the Saddle Again" and as the writer and singer of "Here Comes Santa Claus," is the only entertainer to have a star in every category — film, television, recording, radio, and theater. One of Autry's stars is also one of only two stars which have been stolen from the Walk and never recovered.
It's about one-tenth as long as The Indianapolis Motor Speedway.
In other words, 0.50 kilometers is 0.1242740 times the length of The Indianapolis Motor Speedway, and the length of The Indianapolis Motor Speedway is 8.04674 times that amount.(Speedway, Indiana) (rectangular oval course)
The rectangular oval course of the Indianapolis Motor Speedway is 4.02336 km. While famous for its automotive racing, the first motorsport held at the track was a series of motorcycle races in August, 1909 — a little less than two years before the inaugural Indianapolis 500 race was run.
It's about one-tenth as long as Daytona International Speedway.
In other words, 0.50 kilometers is 0.1242740 times the length of Daytona International Speedway, and the length of Daytona International Speedway is 8.04674 times that amount.(Daytona Beach, Florida) (tri-oval course)
The tri-oval course of the Daytona International Speedway, upon which the NASCAR Daytona 500 is run, is 4.02336 km in length. Although the tri-oval design is said to allow for greater visibility during the race, the real reason for the then-unique design was that plot available for construction of the track was only 350 acres and could not accommodate a traditional oval layout of appropriate length.
It's about eight-and-a-half times as tall as The Cinderella Castle.
In other words, 0.50 kilometers is 8.680 times the height of The Cinderella Castle, and the height of The Cinderella Castle is 0.1150 times that amount.(Fantasyland, Magic Kingdom, Walt Disney World, Lake Buena Vista and Bay Lake, Florida)
Walt Disney World's Cinderella Castle is 0.0576 kilometers tall. The castle's architecture uses the optical trick known as "forced perspective" — the castle gets smaller near the top — to appear larger than it truly is.
