A metric is conformally flat when it is locally a positive scalar multiple of a flat metric. Multiplication by the conformal factor preserves null cones and unparametrized null geodesics.
A conformally flat metric is locally a positive scalar multiple of a flat metric. It makes its domain a conformally flat manifold.
