Earth's circumference can be found out by various methods which are explained below: Method 1: Earth's circumference can be found out by using the geometric formula that was used over 2,000 years ago. Earth rotates around the north-south path once in approximately 24 hours. However, derived from NASA’s value of the (presumably) average diameter of the Earth, 12,756 km, we can approximately calculate is circumference, using equations of the relationship between the diameter or … D.

Express the circumference of the earth in meters. He read that in a city, Syene, little far away from Alexandria, … This is because the Earth isn’t a perfect sphere; it bulges around the equator because it’s rotating on its axis. Eratosthenes is considered the inventor geography, particularly because he developed the system of latitudinal and longitudinal lines to map the world. Circumference of the Earth in meters: 40,075,000 meters Circumference of the Earth in inches: 1,577,727,360 inches. 276 BC to ca. Plato took a guess at Earth’s circumference at 62,800-74,000 kilometers (or 39,250-46,250 miles) while Archimedes was closer with a guess of 55,500 kilometers, or 34,687 miles.
