What is the longitudinal circumference of the earth?

Answer 1

Answer Answer is not possible without morThe distance will be greatest at the equator and deminish the further away from the equator you get( or the closer you get to the North or South Pole ). Any answer to this question would be dependent upon the exact latitude.

Answer 2

The polar circumference (logitudinal circumference) of the Earth is about 40,008 kilometers (24,860 miles). The equatorial circumference of the Earth is about 40,075 kilometers (24,901 miles).

More Precisely:

Earth is not a perfect sphere, but is an oblate spheroid, .336% flattened along the North-South axis. As a consequence, a line of longitude wrapped around the Earth going through the north and south poles is about 24,860 miles, or 40,008 km long. The circumference of the Earth at the equator is about 24,901 miles, or 40,075 km. That makes the Earth's circumference about 41 miles, or a bit more than 67 km larger around its middle than around its poles.

Caveat: The numbers for circumference are necessarily slightly approximate because the surface of the Earth is irregular (mountains, valleys, etc.) so different estimates of circumference may differ by a mile (or kilometer) or so. In addition, though the equator is a well defined line, the polar circumference can be different depending on the line of longitude and that adds additional variability.

Answer 3

The longitudinal circumference of the Earth is approximately 24,901 miles (40,075 kilometers).
