The metre was originally defined as one ten-thousandth of one fourth of the Earth's Polar circumference. i.e. 10 000 m from equator to pole. Giving a total polar circumference of 40 000 km.
If fact the measurement was slightly in error, but the magnitude of that error is known.
What else can I help you with?
What is Polar Circumference?
The polar circumference of the Earth is any great circle that includes both poles. It is shorter than the equatorial circumference because the Earth's spin makes it bulge at the equator, while it is flattened at the poles. The polar circumference at MSL would be 40,008 km, compared to the equatorial circumference of 40,075 km.The term "polar circumference" can also refer to the Arctic and Antarctic circles, which are roughly 66.56 degrees N and S latitude.
What is Earths circumference measured between North and South poles?
The circumference of the Earth measured between the North and South poles is approximately 40,007.86 kilometers.
What is the circumference and diameter of Earth in miles?
The circumference of the earth in miles is about 24,901 miles. The diameter is about 7,926 miles.
What does the difference between the Earth's polar circumference and the Earth's equatorial circumference tell you about the Earth's shape?
The difference between the Earth's polar circumference and equatorial circumference, known as the flattening of the Earth, indicates that the Earth is an oblate spheroid. This means that the Earth is slightly flattened at the poles and bulges at the equator, making it not a perfect sphere.
Earths three main climate zones?
Earth has three main climate zones. These climate zones are the polar zone, the tropical zone, and the temperate zone.
How large is the Earths circumference?
Earth's Circumference is 24,901 miles (40,075 km)
What is Polar Circumference?

The polar circumference at MSL would be 40,008 km, compared to the equatorial circumference of 40,075 km.The term "polar circumference" can also refer to the Arctic and Antarctic circles, which are roughly 66.56 degrees N and S latitude.
Is the Earth's equatorial circumference the same as the polar circumference?
No. The polar circumference of the Earth is smaller than the equatorial circumference by about 41 miles or about 67 km. The Earth is a slightly "oblate spheroid" meaning it is slightly flattened (0.336%) at the poles, and bulging at the equator, due to its spin. The equatorial circumference of the Earth is about 40,075 kilometers (24,901 miles). The polar circumference of the Earth is about 40,008 kilometers (24,860 miles).

In ancient Greece who estimated the earths circumference?
Eratosthenes is credited with calclating the circumference of the Earth at the equivalent of 25,000 miles/40,000km in about 205 BCE.

What is the langth of a dodo bird?

What is the circumference of the Earths moon?
The moon is about one fourth the size of the Earth. It has an equatorial circumference of 10,917 kilometers, or 6783.5 miles.
Where is the equator in a polar projection?
A polar projection of the earth shows a pole (north or south, depending on the projection) at the center of a circular map. The equator is the circumference of the circle.
