How big is the earth in centimeters?

Answer 1

Mmm, well the Earth is round and not square, so it cannot be measure in a flat line, but has to be measured along the curve or around the circumference.

The circumference of the Earth at the Equator, its widest point is 40,075 km (East/ West measurement).

Its meridian circumference is 40,007 km (North/ South measurement - North Pole through the South Pole and back to the North Pole); which means the Earth is a little "shorter" than it is wide.

There are 100 cm in 1 meter, multiply this by 1000 meters and you have 100,000 cm in 1 kilometer.

Therefore:

The equatorial circumference of the Earth is:

40,075 km x 100,000 cm = 4,007,500,000 cm

The meridian circumference of the Earth is:

40,007 km x 100,000 cm = 4,000,700,000 cm; if you divide this by 2, this will give you the distance from the North Pole to the South Pole in cm, which is 2,000,350,000 cm

Answer 2

Earth's diameter is approximately 501 684 480 inches; its circumference is approximately 1 577 727 360 inches; its volume is approximately 8.457 × 1022 cubic inches.

Answer 3

The earth's circumference is approximately 1577756600 inches around, according to Wolfram Alpha.
