It's about one-two-hundred-fiftieth as tall as The Washington Monument.
In other words, 4.20 shaftments is 0.003781 times the height of The Washington Monument, and the height of The Washington Monument is 264.480 times that amount.(Washington, D.C.)
The Washington Monument measures 1,110.80 shaftments tall, with some discrepancy due to the fact that the Monument's base is slightly below the surrounding ground. Interrupted in its construction by the American Civil War, it was almost 36 years between groundbreaking and the completion of construction.
It's about one-two-hundred-fiftieth as tall as St. Paul's Cathedral.
In other words, 4.20 shaftments is 0.00368 times the height of St. Paul's Cathedral, and the height of St. Paul's Cathedral is 272 times that amount.(London, England, United Kingdom)
St. Paul's Cathedral measures 1,140 shaftments to its peak. The southwest tower of the Cathedral contains the bell known as "Great Paul," which is the largest bell in Great Britain at 15,000 kg (16.5 tons), outweighing the more iconic Big Ben bell by about 3,000 kg (3 tons).
It's about one-three-hundredth as tall as The Space Needle.
In other words, 4.20 shaftments is 0.00348 times the height of The Space Needle, and the height of The Space Needle is 287 times that amount.(Seattle, Washington) (to aircraft warning beacon at peak)
Built for a 1962 World's Fair, the Space Needle stands 1,210 shaftments tall. With a track-and-wheel design inspired by railroad mechanics and a precisely-configured balance, the restaurant near the top of the space needle requires just a 1.5 hp motor to rotate at speeds of about 0.053 kph (0.033 mph).
It's about one-three-hundred-fiftieth as tall as The Golden Gate Bridge.
In other words, 4.20 shaftments is 0.00282 times the height of The Golden Gate Bridge, and the height of The Golden Gate Bridge is 355 times that amount.(San Francisco, California and Marin County, California) (height above water)
The height of each tower of Golden Gate Bridge is 1,490 shaftments above the surface of the San Francisco Bay. One of the key designers of the bridge, Charles Ellis, had no engineering degree when he began working on the project, but would later go on to write what became a standard textbook on structural engineering, and would ultimately be forced to complete his calculations on the bridge by working without pay for five months.
It's about 400 times as long as a Strand of Spaghetti (thickness).
In other words, 4.20 shaftments is 380 times the length of a Strand of Spaghetti (thickness), and the length of a Strand of Spaghetti (thickness) is 0.0026 times that amount.(average; restaurant and supermarket applications) (based on FMA Omcan Italian Made TR50 Counter Top Pasta Machine Extruder 13317)
An average strand of restaurant-grade spaghetti measures 0.011 shaftments in thickness. In 2010, a California Buca di Beppo set a world record by preparing a 13,780-lb bowl of spaghetti, served in a swimming pool.
It's about one-four-hundred-fiftieth as long as The QE2.
In other words, 4.20 shaftments is 0.00218 times the length of The QE2, and the length of The QE2 is 459 times that amount.(a.k.a. RMS Queen Elizabeth 2) The QE2 has a total length of 1,930 shaftments. During its voyaging lifetime from 1969 through 2008, it travelled more than 63,000,000,000 shaftments, the furthest cumulative distance by any ship in modern history.
It's about one-five-hundredth as tall as The Eiffel Tower.
In other words, 4.20 shaftments is 0.00198 times the height of The Eiffel Tower, and the height of The Eiffel Tower is 505 times that amount.(a.k.a. La Tour Eiffel) (Paris, France) (to flagpole peak)
The Eiffel Tower stands 2,130 shaftments tall, including its flagpole. The Tower is the largest structure in Paris as most other buildings are governed by a zoning restriction limiting them to a height of 243 shaftments or less.
