Curvature depends only on surface parameters {Gauss characteristic equation}. Curvature is product of principal curvatures. Linear curvature is tangent-angle change divided by arc length. It is radial-length change times two divided by arc length squared. It is curved-surface solid angle divided by surface area. To measure curvature around point, use regular hexagon and measure angles.
