The Empire State Building stands 0.000000000000012348 parsecs 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 350,000,000,000,000,000 times as tall as a Giant Sequoia (tree).
In other words, the height of a Giant Sequoia (tree) is 0.0000000000000000027 times 900 parsecs.(a.k.a. Sequoiadendron giganteum, a.k.a. Sierra redwood, a.k.a. Wellingtonia)
Giant Sequoias of the Giant Sequoia National Monument located in Sierra Nevada, near Visalia, California can grow to heights of 0.0000000000000025 parsecs. The wood from the Giant Sequoias is often brittle and prone to shattering when such trees are felled, and as a result the trees logged in the late nineteenth century were often usable only as shingles or matchsticks.
It's about 85,000,000,000,000,000 times as tall as The Eiffel Tower.
In other words, 900 parsecs is 85,700,000,000,000,000.0 times the height of The Eiffel Tower, and the height of The Eiffel Tower is 0.0000000000000000117 times that amount.(a.k.a. La Tour Eiffel) (Paris, France) (to flagpole peak)
The Eiffel Tower stands 0.0000000000000105 parsecs 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 0.0000000000000012 parsecs or less.
It's about 500,000,000,000,000,000 times as tall as The Leaning Tower of Pisa.
In other words, 900 parsecs is 492,000,000,000,000,000.0 times the height of The Leaning Tower of Pisa, and the height of The Leaning Tower of Pisa is 0.00000000000000000203 times that amount.(a.k.a. The Tower of Pisa, a.k.a. Torre pendente di Pisa) (Pisa, Italy) (height along center axis)
The Leaning Tower of Pisa stands 0.00000000000000183 parsecs tall along the angle of its lean. In May of 2008, in an successful effort to stabilize the tower, 70 tonnes of earth were removed from the tower's base on the side opposite the lean.
It's about 5,000,000,000,000,000,000 times as tall as a Giraffe.

An adult giraffe may grow to be up to 0.0000000000000002 parsecs tall. Adult giraffes require very little sleep, averaging just 1.9 hours per day.
