The equatorial circumference of the Earth is about 40,075 km (24,901 m).
The polar circumference of the Earth is about 40,008 km (24,860 m).
More Precisely:
Earth is not a perfect sphere, but is "flattened" at the poles. Its shape is described as an oblate spheroid. So, the Earth's circumference is about 68 km (41 m), larger around its bellythan around its poles.
This difference is small enough that, were the earth shrunk down to the size of a billiard ball, it would be more perfectly round than most billiard balls.
Caveat: The numbers for circumference are always approximations because Earth's surface is irregular and constantly changing. The tidal bulging (constantly shifting) is a dynamic factor. Polar measurements vary with longitude. So these approximations can differ by a kilometer or two.

What is the equatorial circumference in miles?
The equatorial circumference of the Earth is approximately 24,901 miles.
How do you determine the circumference of the earth if you know a circumference of a smaller latitude and the number of degrees the latitude is from the equator?
You can use the relationship between the circumference of the Earth and the circumference of the smaller latitude to calculate the Earth's circumference. Multiply the circumference of the smaller latitude by the cosine of the latitude. This will give you the circumference of a circle at that latitude, which can then be used to estimate the Earth's circumference.
Where is Earth's circumfrence greatest?
Earth's circumference is greatest at the equator, where it measures approximately 24,901 miles (40,075 kilometers). This is due to the Earth's shape being an oblate spheroid, which means it bulges at the equator and is flatter at the poles.
How much is the average size of earth's circumference?
The average circumference of Earth is approximately 24,901 miles (40,075 kilometers).
Circumference of Venus's compared to earth?
The circumference of Venus is approximately 24,901 miles, while the circumference of Earth is about 24,901 miles. Despite their similar circumferences, Venus has a much hotter and inhospitable environment compared to Earth.
