Surface finish standards conversion

Is a conversion chart or formula available whereby I may convert a metric surface finish callout (e.g., N5) to an equivalent RMS surface finish standard?

There are a lot of charts available and free that have tables or convert inches to millimeters. The conversion factor is 1 inch = 25.4 millimeters.
