It's about 550 times as tall as The Great Pyramid of Giza
In other words, the height of The Great Pyramid of Giza is 0.0018 times 71 kilometers.(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 0.130 kilometers. 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 one-five-hundred-fiftieth as long as The Circumfrence of Earth
In other words, 71 kilometers is 0.0017716775 times the length of The Circumfrence of Earth, and the length of The Circumfrence of Earth is 564.436810 times that amount.(Equatorial)
The Earth — not a perfect sphere, but rather an oblate spheroid with bulged middle — has an Equatorial circumference of approximately 40,075.014 kilometers. The first airplane trip around the circumference of the Earth (with a few stops along the way), was completed in 1924 by the United States Army Air Service, and took 175 days.
It's about 650 times as long as a Football field
In other words, 71 kilometers is 647.055 times the length of a Football field, and the length of a Football field is 0.00154546 times that amount.(American) (total distance; per NFL regulation)
According to NFL specifications, an American football field should measure 0.1097280 kilometers from end to end. Because each team's goalpost is located at the far end of the scoring area (end zone), a ball on a scoring play may need to travel as many as 0.009144 kilometers farther when kicked into the scoring area than when run (rushed) or passed into it.
It's about 700 times as long as a Football (Soccer) Pitch
In other words, 71 kilometers is 676 times the length of a Football (Soccer) Pitch, and the length of a Football (Soccer) Pitch is 0.00148 times that amount.(a.k.a. Football Field, a.k.a. Soccer Field) (field length, a.k.a. touchline distance)
According to the Laws of the Game, a football pitch should measure between 0.1050 kilometers (when the Laws were originally, they used imperial measurements of 0.1050 kilometers, and later converted to the metric units used today). The goal markess were defined as part of the pitch by the original rules of the game in the late 16th century, but it was not until the mid 19th century that the crossbar and the net were added
It's about 750 times as tall as Big Ben
In other words, the height of Big Ben is 0.0014 times 71 kilometers.(officially the clock tower of Palace of Westminster, a.k.a. Houses of Parliament) (London, England)
The clock tower of the Palace of Westminster, which houses the bell known as "Big Ben," rises 0.096 kilometers. The tower has no elevator, and is therefore only accessible by climbing 334 steps to the top.
It's about 750 times as tall as The Statue of Liberty
In other words, 71 kilometers is 763.50 times the height of The Statue of Liberty, and the height of The Statue of Liberty is 0.00131 times that amount.(a.k.a. "Liberty Enlightening the World," a.k.a. La Liberté Éclairant le Monde) (Liberty Island, New York City, New York) (pedestal base to torch peak)
The Statue of Liberty reaches 0.09299 kilometers including the pedestal. The statue was designed using an optical trick known as "forced perspective" to make the statue appear proportionally correct when viewed from its base and is, in actuality, disproportionately large at the top.
It's about 950 times as tall as a Giant Sequoia (tree)
In other words, the height of a Giant Sequoia (tree) is 0.0011 times 71 kilometers.(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 0.076 kilometers. 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.
