Built for a 1962 World's Fair, the Space Needle stands 0.000000000000005960 parsecs 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 100 times as long as an Aspirin
In other words, 0.0000000000000000550 parsecs is 120 times the length of an Aspirin, and the length of an Aspirin is 0.0083 times that amount.(for up & up aspirin, 325mg, regular strength tablets) (a.k.a. acetylsalicylic acid, a.k.a. ASA)
A single aspirin tablet measures 0.000000000000000000450 parsecs in diameter. One of the most common medicines in the world and a foundation of worldwide health systems, an estimated 40,000 metric tons of aspirin are consumed each year.
It's about one-one-hundred-fiftieth as tall as The Golden Gate Bridge
In other words, 0.0000000000000000550 parsecs is 0.00748 times the height of The Golden Gate Bridge, and the height of The Golden Gate Bridge is 134 times that amount.(San Francisco, California and Marin County, California) (height above water)
The height of each tower of Golden Gate Bridge is 0.000000000000007360 parsecs 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 one-one-hundred-fiftieth as long as The QE2
In other words, 0.0000000000000000550 parsecs is 0.00577 times the length of The QE2, and the length of The QE2 is 173 times that amount.(a.k.a. RMS Queen Elizabeth 2)
The QE2 has a total length of 0.000000000000009530 parsecs. During its voyaging lifetime from 1969 through 2008, it travelled more than 0.0000003110 parsecs, the furthest cumulative distance by any ship in modern history.
