WebAug 7, 2016 · At a single point, off-diagonal elements of the metric tensor simply say that your coordinate system is not orthogonal. For example, if you use x ^ and x ^ + y ^ as your basis in the plane, the resulting metric has a cross term. Since the metric tensor is symmetric, you can always diagonalize it at a single point, so that's not very interesting.
