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 the earth's polar circumference?
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 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.
Is sodium iodide polar or non polar?
Sodium iodide is an ionic compound, so it does not have traditional covalent bonds and is not classified as either polar or nonpolar.
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 is the equatorial circumference of earth in miles?
The equatorial circumference of the earth is 24901.45 miles (40075.02 km).
What is the earth's polar circumference?
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.
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). See related questions and links for additional details.
The circumference of the earth from pole to pole is how many miles?
The polar circumference of the earth is 24860.535 miles (according to www.koordinaten.de/english/informations/earth.shtml)
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.
The difference between the North and Southpole?
That's 1/2 the polar circumference of the Earth ... about 12,430 miles.
What is the circumference of longitude at the prime meridian?
All meridians of longitude join the Earth's north and south pole, so the length of every meridian is 1/2 of the Earth's polar circumference.
How is a meter and other variable are defined today?
1 meter is one forty-millionth of the polar circumference of Earth.
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.
What is the polar circumference of the earth?
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.
How many kilo meters is the circumference of the earth?
Call it 40,000, you'll be near enough for Wiki... The metre is defined as one-forty-millionth of the polar circumference, it's a little higher at the equator because of the spin...
How many miles is it from the equator to the South Pole?
That's nominally 1/4 of the Earth's polar circumference, which you can easily find online.
When was the the circumference of the Earth first measured and by who?
One possible person is Eratosthenes of Cyrene ~230 BC as he was a Greek scientist who calculated the circumference of the Earth, with remarkable accuracy (some values for the "stadia" he used gives a result within 6% of the actual polar circumference). See link for further information
