Earth's circumference is the distance around Earth.Measured around the equator, it is 40,075.017 km (24,901.461 mi).Measured passing through the poles, the circumference is 40,007.863 km (24,859.734 mi). [1]Treating the Earth as a sphere, its circumference would be its single most important measurement. [2] The first known scientific measurement and calculation was done by Eratosthenes, by ...

2015年12月24日 · The equatorial circumference of the Earth is 40,075 km. This is the distance around the equator of the Earth. If you measure the circumference of the Earth, while passing through the poles, the ...

2021年7月6日 · The equatorial circumference of Earth is 24,901 miles (40,075 km). However, from the North Pole to the South Pole, the so-called meridional circumference is smaller, at 24,860 miles (40,008 km).

2025年2月11日 · The Earth’s equatorial circumference has been measured with increasing precision over time. The measurement at the equator is 40,075 km (24,901 miles). A value of 40,074 km (24,901 miles) represents the equatorial great circle measurement. The precise equatorial measurement is 40,075.017 km (24,901.55 miles), rounded to 40,075.16 km (24,901. ...

Technically The Earth is an oblate ellipsoid, an ellipse rotated about its minor axis, with an equatorial radius of 6,378.1 kilometers (3963 miles), and equatorial of diameter of 12,742 kilometers (7917 miles) and an equatorial circumference of 40,075 kilometers (24,901 miles), which is slightly greater than the polar radius of 6,356.7 ...

The circumference of the Earth can be calculated using the formula, Circumference = 2 πR or π D, where R is the radius of Earth and D is the diameter. By knowing the Equatorial diameter or the polar diameter of the Earth, the circumference can be found. T he circumference of the Earth (around the equator) is approximately 24,887 miles.

2017年4月25日 · The circumference of Earth varies depending on the method used to measure it. The measurement around the equator and from pole to pole differs because Earth is not a perfect sphere rather it bulges at the equator and flattens at the poles. Earth, unlike other planets, has only one moon while a total of 166 moons in the solar system have been ...

2009年9月22日 · The Earth’s circumference – the distance around the equator – is 40,075 kilometers around. That’s sounded nice and simple, but the question is actually more complicated than that.

2009年3月2日 · The circumference of the Earth in kilometers is 40,075 km, and the circumference of the Earth in miles is 24,901. ... If you measure the circumference around the Earth’s equator, you get the ...

Method to Calculate the Earth’s Circumference. We can use a mathematical formula to find the circumference of the Earth as follows: Circumference of Earth at the equator (CE): CE = π × D = 3.14 × 7926 = 24,887.64 miles (which is close to 24,901 miles) Circumference of Earth around the poles (CP): CP = π × D = 3.14 × 7900 = 24,806 miles ...
