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]
Heinz Stücke has been cycling around the world since 1962. Arthur Blessitt has been walking around the world carrying a 45 lb (20 kg) wooden cross since 25 December 1969, covering 42,279 miles (68,041 km) through 324 countries. As of 13 June 2008, aged 67, he had walked in every country of the world, since when he has returned to some.

This is a list of countries (or regions) by total road network size, both paved and unpaved.Also included is additional data on road network density and the length of each country or region's controlled-access highway network (also known as a motorway, expressway, freeway, etc.), designed for high vehicular traffic.
Earth radius (denoted as R 🜨 or R E) is the distance from the center of Earth to a point on or near its surface. Approximating the figure of Earth by an Earth spheroid (an oblate ellipsoid), the radius ranges from a maximum (equatorial radius, denoted a) of nearly 6,378 km (3,963 mi) to a minimum (polar radius, denoted b) of nearly 6,357 km (3,950 mi).
