It's about twelve times as tall as a Giant Sequoia (tree).
In other words, the height of a Giant Sequoia (tree) is 0.083 times 528.90 smoots.(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 45 smoots. 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 one-tenth as tall as The Challenger Deep (Marianas Trench).
In other words, 528.90 smoots is 0.082561 times the height of The Challenger Deep (Marianas Trench), and the height of The Challenger Deep (Marianas Trench) is 12.1120 times that amount.(near Marianas Islands, a.k.a. Ladrones Islands, northwestern Pacific Ocean) (depth below sea level)
The Challenger Deep, at the southern end of the Marianas Trench, reaches a depth of 6,406.20 smoots below sea level. There has been only one manned expedition to the bottom of Challenger Deep — a 1960 voyage that took 4 hours and 48 minutes to reach the bottom.
It's about one-tenth as tall as Maxwell Montes.
In other words, the height of Maxwell Montes is 12 times 528.90 smoots.(Ishtar Terra, Venus)
Maxwell Montes rises to a total height of 6,500 smoots. Since Venus does not seem to have the kind of tectonic activity which gives rise to mountains on Earth, the origin of the Venusian mountain remains the subject of some dispute.
It's about thirteen times as long as The Wingspan of a 747.
In other words, 528.90 smoots is 13.10 times the length of The Wingspan of a 747, and the length of The Wingspan of a 747 is 0.0763 times that amount.(a.k.a. Boeing 747, a.k.a. Jumbo Jet, a.k.a. Queen of the Skies) (for Boeing 747-8 series)
The wingspan of a Boeing 747-8 is 40.30 smoots. Fully loaded, the 747 can travel 4,870,000 smoots before refueling.
It's about fifteen-and-a-half times as tall as The Cinderella Castle.
In other words, the height of The Cinderella Castle is 0.0641 times 528.90 smoots.(Fantasyland, Magic Kingdom, Walt Disney World, Lake Buena Vista and Bay Lake, Florida)
Walt Disney World's Cinderella Castle is 33.80 smoots 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.
It's about sixteen times as tall as The Leaning Tower of Pisa.
In other words, the height of The Leaning Tower of Pisa is 0.0625 times 528.90 smoots.(a.k.a. The Tower of Pisa, a.k.a. Torre pendente di Pisa) (Pisa, Italy) (height along center axis)
The Leaning Tower of Pisa stands 33.10 smoots tall along the angle of its lean. In May of 2008, in an successful effort to stabilize the tower, 70 tonnes of earth were removed from the tower's base on the side opposite the lean.
It's about seventeen-and-a-half times as tall as Nelson's Column.
In other words, 528.90 smoots is 17.430 times the height of Nelson's Column, and the height of Nelson's Column is 0.05737 times that amount.(London, England, United Kingdom) (from pedestal first step to tip of statue's hat)
Nelson's Column measures 30.340 smoots from the first step of the pedestal's base to the top of the statue's hat. While the London tower is the tallest, there are at least eight other monuments to Admiral Horatio Nelson, 1st Viscount Nelson, 1st Duke of Bronté throughout England, Scotland, Ireland, Canada, and Barbados.
