It's about as long as The QE2.
It's about nine-tenths as tall as The Eiffel Tower.
In other words, 294,000,000 microns is 0.9070 times the height of The Eiffel Tower, and the height of The Eiffel Tower is 1.10 times that amount.(a.k.a. La Tour Eiffel) (Paris, France) (to flagpole peak)
The Eiffel Tower stands 324,000,000 microns 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 37,000,000 microns or less.
It's about three-fourths as tall as The Empire State Building.
In other words, 294,000,000 microns is 0.771630 times the height of The Empire State Building, and the height of The Empire State Building is 1.2960 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
It's about one-and-three-tenths times as tall as The Golden Gate Bridge.
In other words, the height of The Golden Gate Bridge is 0.7690 times 294,000,000 microns.(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 Petronas Twin Towers.
In other words, 294,000,000 microns is 0.65060 times the height of The Petronas Twin Towers, and the height of The Petronas Twin Towers is 1.5370 times that amount.(a.k.a. Menara Berkembar Petronas, a.k.a. Petronas Towers) (Kuala Lumpur, Malaysia) (to spire)
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-three-fifths times as tall as The Space Needle.
In other words, the height of The Space Needle is 0.6250 times 294,000,000 microns.(Seattle, Washington) (to aircraft warning beacon at peak)
Built for a 1962 World's Fair, the Space Needle stands 184,000,000 microns 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 three-fifths as tall as The Shanghai World Financial Center.
In other words, 294,000,000 microns is 0.5980 times the height of The Shanghai World Financial Center, and the height of The Shanghai World Financial Center is 1.670 times that amount.(上海环球金融中 上海環球金融中心, Shànghǎi huánqiú jīnróng zhōngxīn) (a.k.a. SWFC) (Shanghai, China) (to spire)
The Shanghai World Financial Center is 492,000,000 microns tall to its roof. It is home to both the world's highest hotel (on its 79th through 93rd floors) and the world's tallest observation deck (on its 100
