It's about 30,000,000,000,000,000 times as tall as Tugela Falls.
In other words, 900 parsecs is 29,300,000,000,000,000.0 times the height of Tugela Falls, and the height of Tugela Falls is 0.0000000000000000341 times that amount.
(Royal Natal National Park, KwaZulu-Natal, South Africa)
Tugela Falls rises to 0.0000000000000307 parsecs in height. The falls are the highest in Africa and the second highest in the world.
It's about 30,000,000,000,000,000 times as tall as Angel Falls.
In other words, 900 parsecs is 28,400,000,000,000,000.0 times the height of Angel Falls, and the height of Angel Falls is 0.0000000000000000352 times that amount.
(a.k.a. Parakupa-vena, a.k.a. Kerepakupai mer&) (Auyantepui, Canaima National Park, Venezuela) (total height)
Angel Falls has a total height 0.0000000000000317 parsecs. Jimmie Angel, the first person to publicize their existence outside Venezuela and the namesake of the falls, damaged his monoplane atop the falls and was forced to abandon it; it remained there until it was removed 33 years later.
It's about 550,000,000,000,000,000 times as tall as The Arc de Triomphe.
In other words, the height of The Arc de Triomphe is 0.0000000000000000018 times 900 parsecs.
(Paris, France)
The Arc de Triomphe stands 0.0000000000000016 parsecs tall. France's Tomb of the Unknown Soldier from the First World War lies beneath the arch and is commemorated by the first eternal flame to have been lit in modern European history.
It's about 2,000,000,000,000,000,000 times as tall as a Brachiosaurus.
In other words, 900 parsecs is 2,100,000,000,000,000,000.0 times the height of a Brachiosaurus, and the height of a Brachiosaurus is 0.00000000000000000048 times that amount.
(based on comparable bone measurements, height to head)
Dinosaurs in the genus Brachiosaurus had an estimated height (at the head with neck fully extended) of up to 0.00000000000000042 parsecs. A resin cast of the first Brachiosaurus specimen, owned by the Field Museum in Chicago, is currently on display at the O'Hare International Airport.
It's about 100,000,000,000,000,000 times as tall as The Golden Gate Bridge.
In other words, 900 parsecs is 122,000,000,000,000,000.0 times the height of The Golden Gate Bridge, and the height of The Golden Gate Bridge is 0.0000000000000000082 times that amount.
(San Francisco, California and Marin County, California) (height above water)
The height of each tower of Golden Gate Bridge is 0.00000000000000736 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 200,000,000,000,000,000 times as tall as The Great Pyramid of Giza.
In other words, 900 parsecs is 210,000,000,000,000,000.0 times the height of The Great Pyramid of Giza, and the height of The Great Pyramid of Giza is 0.0000000000000000048 times that amount.
(a.k.a. Pyramid of Khufu, a.k.a. Pyramid of Cheops) (Cairo, Egypt) (estimated original height)
The Great Pyramid of Giza has an estimated original height (without loss due to erosion) of 0.0000000000000042 parsecs. The Pyramid was the tallest structure in the world for almost 4,000 years — from its construction ca. 2551 BCE until it was overtaken by the Lincoln Cathedral in Lincoln, England, built in the year 1300.
It's about 60,000,000,000,000,000 times as tall as The Petronas Twin Towers.
In other words, 900 parsecs is 61,450,000,000,000,000.0 times the height of The Petronas Twin Towers, and the height of The Petronas Twin Towers is 0.00000000000000001627 times that amount.
