When the metric system born, the kilometer was defined as 1/10000 of the distance from the equator to a pole.
If you start in a pole, goes to the opposite pole and return to the first one, you would travel 40,000 kms.. The equator line is a little larger than 40,000 kms due to Earth form.

The length of Earth's equator is about 40,075.0 km, or 24,901.5 miles. The exact length is 40,075,016.6856 m in WGS-84, and 40,075,035.5351 m in IAU-2000.

Approximately 25,000 miles. The radius of the earth is about 3,960 miles. To find the circumference, simply double the radius to find the diameter, and then multiply that by Ï, which is about 3.14159.
C = 2Ïr = 2r x Ï
C = 2 (3960 mi) x Ï
C = 7920 mi x (3.14159)
C = 24,881 mi.

It's about the same as the measurement of the circumference of the Earth

It encircles the earth at its fattest point, and is therefore very long indeed, about 25000 miles.

yep just over 24,000 thats why you get 24 and a bit hours in a day ( the bit i refer to gets made up on leap year)
