The Earth’s diameter is 12,756 kilometers — that’s the thickness or width of the planet.
The circumference of the Earth is about 40,075 kilometers at the equator.
In the Metric System, one kilometer equals 1000 meters and one meter equals 100 centimeters.
So the Earth’s diameter is 12,756,000 meters or 1,275,600,000 centimeters, and the Earth’s circumference is 40,075,000 meters or 4,007,500,000 centimeters!
Pretty huge, huh?
