It's about eight-and-a-half times as long as The QE2.

It's about one-tenth as tall as Olympus Mons.
In other words, the height of Olympus Mons is 11 times 34.640 leas.(a.k.a. Mount Olympus) (Mars)

In other words, 34.640 leas is 11.20 times the height of The Golden Gate Bridge, and the height of The Golden Gate Bridge is 0.0893 times that amount.(San Francisco, California and Marin County, California) (height above water)
The height of each tower of Golden Gate Bridge is 3.10 leas 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 fourteen times as tall as The Space Needle.
In other words, 34.640 leas is 13.80 times the height of The Space Needle, and the height of The Space Needle is 0.0725 times that amount.(Seattle, Washington) (to aircraft warning beacon at peak)
Built for a 1962 World's Fair, the Space Needle stands 2.520 leas 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).
