WebSep 22, 2004 · If the equatorial radius of Earth is 6378 kilometers, the circumference comes to 40074 kilometers--slightly more than the 40,000 kilometers supposed to be the pole-to-pole circumference, implied by the definition of "one meter." The difference comes because the Earth bulges out at its equator. Earth radius (denoted as R🜨 or $${\displaystyle R_{E}}$$) is the distance from the center of Earth to a point on or near its surface.
