During its voyaging lifetime from 1969 through 2008, it travelled more than 9,600,000,000,000,000.000000000000000000 microns, the furthest cumulative distance by any ship in modern history.
It's about nine-tenths as tall as The Empire State Building.
In other words, 324,000,000 microns is 0.850370 times the height of The Empire State Building, and the height of The Empire State Building is 1.1760 times that amount.(New York City, New York) (to top of building)
The Empire State Building stands 381,010,000 microns to its architectural peak. The spire emerging from the top of the building was originally intended to be a mooring mast for blimps whose passengers could disembark onto a landing platform on the 102

Each of the Petronas Towers stands 451,900,000 microns to their spires. Holding the record as the tallest buildings in the world from 1998 to 2004, the towers continue to hold the record for the deepest foundation barrettes — up to 115,000,000 microns deep.
It's about one-and-two-fifths times as tall as The Golden Gate Bridge.
In other words, 324,000,000 microns is 1.430 times the height of The Golden Gate Bridge, and the height of The Golden Gate Bridge is 0.6990 times that amount.(San Francisco, California and Marin County, California) (height above water)
The height of each tower of Golden Gate Bridge is 227,000,000 microns 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 two-thirds as tall as The Shanghai World Financial Center.
