It's about eleven times as tall as a Giant Sequoia (tree).
In other words, the height of a Giant Sequoia (tree) is 0.091 times 473 fathoms.(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 42 fathoms. 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 twelve-and-a-half times as long as The Wingspan of a 747.
It's about one-fifteenth as tall as The Challenger Deep (Marianas Trench).
In other words, 473 fathoms is 0.079345 times the height of The Challenger Deep (Marianas Trench), and the height of The Challenger Deep (Marianas Trench) is 12.6030 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 5,961.30 fathoms 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-fifteenth as tall as Maxwell Montes.
In other words, the height of Maxwell Montes is 13 times 473 fathoms.(Ishtar Terra, Venus)
Maxwell Montes rises to a total height of 6,000 fathoms. 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 fifteen times as tall as The Cinderella Castle.
In other words, the height of The Cinderella Castle is 0.0667 times 473 fathoms.(Fantasyland, Magic Kingdom, Walt Disney World, Lake Buena Vista and Bay Lake, Florida)
Walt Disney World's Cinderella Castle is 31.50 fathoms 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 fifteen-and-a-half times as tall as The Leaning Tower of Pisa.
In other words, the height of The Leaning Tower of Pisa is 0.0654 times 473 fathoms.(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 30.80 fathoms 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 times as tall as Nelson's Column.
In other words, 473 fathoms is 16.750 times the height of Nelson's Column, and the height of Nelson's Column is 0.0597 times that amount.(London, England, United Kingdom) (from pedestal first step to tip of statue's hat)
Nelson's Column measures 28.240 fathoms 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.
