We find a new family of non-separable coordinate transformations bringing theFRW metrics into the manifestly conformally flat form. Our results are simpleand complete, while our derivation is quite explicit. We also calculate all theFRW curvatures, including the Weyl tensor.Comment: 19 pages; LaTeX; no figures; misprints corrected, a few references and short notes adde
