Well, I'd guess geographical, because that would make the polar circumference line perpendicular to the equatorial circumference line. That's why I'd like to get the magnetic circumference if at all possible.

Of course! I didn't picture the line going through the poles as viewed from the side -- it's an ellipse! Using 2*pi*r would understate the perimeter of that shape. OK, that explains why their circumference is greater than what I calculated. Well, does anyone have an answer to whether the...

I was just trying to get the actual range of circumferences for the Earth depending on which way you measure (just based on math, of coure, I know the actual circumference could be considered nearly infinite depending on the length of your ruler). Wikipedia has a very nice table of stats...
