It's about 0.00000002 times as long as The QE2
In other words, 0.0000390 shaftments is 0.00000002020 times the length of The QE2, and the length of The QE2 is 49,500,000 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 0.00000003 times as tall as The Golden Gate Bridge
In other words, 0.0000390 shaftments is 0.00000002620 times the height of The Golden Gate Bridge, and the height of The Golden Gate Bridge is 38,200,000 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 0.00000003 times as tall as The Space Needle
In other words, 0.0000390 shaftments is 0.00000003230 times the height of The Space Needle, and the height of The Space Needle is 31,000,000 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 0.00000004 times as tall as St. Paul's Cathedral
In other words, 0.0000390 shaftments is 0.00000003420 times the height of St. Paul's Cathedral, and the height of St. Paul's Cathedral is 29,200,000 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 0.00000004 times as tall as The Washington Monument
In other words, 0.0000390 shaftments is 0.0000000351090 times the height of The Washington Monument, and the height of The Washington Monument is 28,483,000 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 0.00000004 times as tall as The Singapore Flyer (Ferris wheel)
In other words, 0.0000390 shaftments is 0.0000000360 times the height of The Singapore Flyer (Ferris wheel), and the height of The Singapore Flyer (Ferris wheel) is 27,800,000 times that amount.(a.k.a. 新加坡摩天观景轮, a.k.a. சிங்கப்பூர் ஃப்ளையர், a.k.a. Pelayang Singapura) (Marina Centre, Singapore)
The Singapore Flyer has a height of 1,080 shaftments. Based on recommendations from Feng Shui masters, the wheel was re-engineered to spin in the opposite direction five months after it began operating.
It's about 0.00000004 times as long as The Seventeenth hole of Pebble Beach
In other words, 0.0000390 shaftments is 0.00000003670 times the length of The Seventeenth hole of Pebble Beach, and the length of The Seventeenth hole of Pebble Beach is 27,200,000 times that amount.(fully Pebble Beach Golf Links) (Pebble Beach; Monterey, California) (from Blue Tee)
The seventeenth hole on Pebble Beach Golf Links is a par 3 measuring 1,060 shaftments from the blue tee. This hole was the site of professional golfer Jack Nicklaus' 1972 U.S. Open win, which included a 1-iron shot that bounced off the hole's flag and resulted in a birdie.
