Well, here are some numbers to make you think again! The circumference of the Earth is about 40,000 kilometers or 24,900 miles. This refers to how big the Earth is around itâs fattest middle part, like if you were to measure the length of a string going around the center of the Earth at the equator.ell, here are some numbers to make you think again!
