... ur welcome.
The circumference of the Earth at the equator is about 24,901 miles, or 40,075 km. Earth is not a sphere, but is "flattened" at the poles. or oblate spheroid.

The molten iron and medals inside the earths core are the reasons for the earths magnetic core.
no it is not true. there is solid iron and nickel in the Earths core

the circumference of Jupiter or its equatorial diameter is 71,492 ± 4 km(11.209 times that of earths)
The moon is about one fourth the size of the Earth. It has an equatorial circumference of 10,917 kilometers, or 6783.5 miles.
Earth's Circumference is 24,901 miles (40,075 km)
Equatorial Circumference Metric: 439,263.8 km - English: 279,118 miles http://solarsystem.nasa.gov/planets/compchart.cfm?Object1=Jupiter Diameter Metric: 142,984 km - English: 88,846 miles http://nssdc.gsfc.nasa.gov/planetary/factsheet/index.html
The equatorial circumference is about 40 000 km. This was the original definition of the metre, though better measurements now mean we know the error. [Actually the definition was of 10 000 km for 1/4 of the circumference].
Imaginary line around Earth's axis is horizontal.
The Earth takes 23 hours and 56 minutes to rotate once an the Earths equatorial circumference measures40,075.017km (= 1577756574.8 inches).Thus it rotates at a speed of 1577756574.8/24 = 65739857.28333333 inches an hour.
The equatorial diameter is greater than the polar diameter. The distance is about 30 miles. The equatorial diameter is about 7927 miles. The polar diameter is about 7900 miles.
The Earths Equatorial diameter is 12756 km, and there are (on average) 149,597,890 km to the sun, so we are talking about 11728 Earths.
According to NASA, the earth's equatorial radius (not raduis) is 6378.1 km.
There are no such thing as "earths measurements" - unless you are referring to the ways in which different earths (i.e., soils) are measured. Soils are typically measured in terms of density, PH, moisture, salinity, sand content, organic content, and biological content. Nitrogen and phosphorus measurements are also common. If you are looking for commonly reffered to measurements of the planet earth, consider asking for "earth's measurements." Or consult the wikipedia page for "earth."
Eratosthenes is credited with calclating the circumference of the Earth at the equivalent of 25,000 miles/40,000km in about 205 BCE.
