It's about one-four-thousand-five-hundredth as tall as St. Paul's Cathedral
In other words, 37.50 milimeters is 0.00022 times the height of St. Paul's Cathedral, and the height of St. Paul's Cathedral is 4,630 times that amount.(London, England, United Kingdom)
St. Paul's Cathedral measures 174,000 milimeters to its peak. The southwest tower of the Cathedral contains the bell known as "Great Paul," which is the largest bell in Great Britain at 15,000 kg (16.5 tons), outweighing the more iconic Big Ben bell by about 3,000 kg (3 tons).
It's about one-five-thousandth as tall as The Space Needle
In other words, 37.50 milimeters is 0.00020 times the height of The Space Needle, and the height of The Space Needle is 4,900 times that amount.(Seattle, Washington) (to aircraft warning beacon at peak)
Built for a 1962 World's Fair, the Space Needle stands 184,000 milimeters 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 5,000 times as long as a Red Blood Cell
In other words, 37.50 milimeters is 5,000 times the length of a Red Blood Cell, and the length of a Red Blood Cell is 0.000 times that amount.(a.k.a. RBCs, a.k.a. haematids, a.k.a. erythrocyte, a.k.a. erythroid cells, a.k.a. red blood corpuscles)
An average Red Blood Cell measures 7.5 µm (micrometers) in diameter. An average human has 20 - 30 trillion red blood cells in their body and each cell completes a circulatory lap in about 20 seconds.
It's about one-six-thousandth as tall as The Golden Gate Bridge
In other words, 37.50 milimeters is 0.00017 times the height of The Golden Gate Bridge, and the height of The Golden Gate Bridge is 6,060 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 milimeters 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 6,500 times as long as a Cell's Nucleus
In other words, 37.50 milimeters is 6,300 times the length of a Cell's Nucleus, and the length of a Cell's Nucleus is 0.0002 times that amount.(for animal cell)
The nucleus of an animal cell measures an average of 0.006 milimeters. The nucleus is the largest organelle in these cells, accounting for about 10% of the cell's total volume.
It's about one-eight-thousandth as long as The QE2
In other words, 37.50 milimeters is 0.00013 times the length of The QE2, and the length of The QE2 is 7,810 times that amount.(a.k.a. RMS Queen Elizabeth 2)
The QE2 has a total length of 294,000 milimeters. During its voyaging lifetime from 1969 through 2008, it travelled more than 9,600,000,000,000 milimeters, the furthest cumulative distance by any ship in modern history.
It's about one-eight-thousand-five-hundredth as tall as The Eiffel Tower
In other words, 37.50 milimeters is 0.00012 times the height of The Eiffel Tower, and the height of The Eiffel Tower is 8,620 times that amount.(a.k.a. La Tour Eiffel) (Paris, France) (to flagpole peak)
The Eiffel Tower stands 324,000 milimeters 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 milimeters or less.
