Hm. You want the estimate or the actual data?
The circumference of the earth at the equator is 24,901.55 miles (40,075.16 kilometers). However, if you measure the earth through the poles the circumference is a bit shorter - 24,859.82 miles (40,008 km). Thus the earth is a tad wider than it is tall, giving it a slight bulge at the equator. http://geography.about.com/od/geographyglossaryc/g/ggcircumference.htm
Diameter: 12,753 km (7,926 miles) Rotation Period with respect to Sun (Length of Day): 24 hrs
The circumference of the Earth is measured in units of length or distance such as miles and kilometers
kilometers
Eratosthenes was the first to measure the Earth's circumference pretty acurately.
There is no error. The Earth is NOT a sphere, it is an oblate spheroid. This is caused by the fact that it is spinning. The spin makes the middle (the equator) bulge out. Thus if you measure the radius to the equator it is 6,378.1 km, while if you measure the radius to a pole it is 6,356.8 km.
The circumference of Venus is very nearly the same as the Earth's. The Earth has a circumference of about 40,000 km while Venus has 38,000 km, making Venus' circumference about 95% the circumference of the Earth.
If two observers AT EXACTLY THE SAME MOMENT will measure the altitude angle of the Sun above the horizon, then you can calculate the size of the Earth.
The circumference of Earth at the equator is about 24,874 miles.
Eratosthenes was the first to measure the Earth's circumference pretty acurately.
His prime objective was to measure a degree on the equator to calculate the circumference of the earth.Studies have shown there has been a large increase in waist circumference in young people.The earth's circumference was accurately measured around 240 BCE by Eeratosthenes.It isn't easy to measure the circumference of large items.
To find how big is the earth in miles, you can measure the circumference about the equator. This is approximately 24,900 miles. However, the circumference about the poles is slightly smaller at 24,859 miles.
The earth does not have a perimeter. The Perimeter is the distance around a circle. The earth is not a circle, but a sphere (sort of). The measurement around the earth is the circumference. Because the earth is not a perfect sphere, the circumference is different depending on whether you measure it horizontally (the equator) or vertically through the poles (Meridian).

The Earth is 3.64 times larger than Moon's Circumference. (Earth's Circumference) 39,843 divide by (Moon's Circumference) 10,921=3.64
The circumference of Venus is very nearly the same as the Earth's. The Earth has a circumference of about 40,000 km while Venus has 38,000 km, making Venus' circumference about 95% the circumference of the Earth.
Measure the diameter of a penny, convert to meters, and divide the circumference of Earth (which is about 40 million meters) by this value.
The circumference of a circle measures the distance around the circle.
== == Given that the circumference of the earth is 40,075.02 km (measured at the equator) the circumference in inches is roughly 1,577,756,664 inches.
The circumference of the earth at the equator is 24,901.55 miles (40,075.16 kilometers).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).
If a person were to measure the earth around the equator, it's 24,901.55 miles. If the earth is measured around the poles, the circumference is a bit shorter at 24,859.82 miles.
