equatioral : 40,075 km
polar : 40,008 km

The circumference of the earth at the equator is 24,902 miles / 40,076 km.
But, if you measure the earth through the poles the circumference is a bit shorter - 24,859.82 miles (40,008 km). This the earth is a tad wider than it is tall, giving it a slight bulge at the equator. This shape is known as an ellipsoid or more properly, geoid (earth-like).

The average radius of the Earth is 3,959 miles (6,374 kilometers).
The equitorial diameter of the Earth (distance from one side of the Earth to the other at the equator) is about 7,926 miles.
The ratio of the circumference to the diameter of a circle (circumference/diameter)
is written as the symbol pi.
Pi is approximately 3.141592.
3.14159265
3.1415926535
Therefore, to determine the circumference from the diameter given above:
equitorial diameter x 3.141592 = equitorial circumference
| |
7,926 x 3.141592 = 24,900
| |
The earth has a circumference of approximately 24,900 miles.
More precisely the circumference of the earth
at the equator is 24,902 mi / 40,076 km.

When the French were inventing metric measurement, they defined a metre as 1 ten millionth of the distance from the geographic north pole to the equator.
The circumference of the Earth, measured round the poles therefore becomes 40 million metres, or 40 thousand kilometres.

which direction?? Equatorial or Polar?
equatioral circumference: 40,075 km
polar circumference: 40,008 km
Considering Napoleon decided that the meter should be 1/40,000,000 of the polar circumference, we can tell that the measurements were 8 km off... 0,02 percent... not bad.. ;)
