Wyatt, I would say 180. Another question at what North or South latitude is a grid square, square?

Art, KC6UQH

I don't think they are EVER really square because longitude lines are never really parallel. They approach square/parallel at the equator, but they are always going to have only the two sides defined by latitude lines parallel (what's that, a rhombus?). And at the pole the north and southmost squares are actually triangles, no? So I would say if you are standing at the pole, unless you have infinitely small feet and can really stand exactly on the pole, the number of grid squares you are in depends on how wide your feet are and how far apart they are when you are standing :-)

Fun questions!
