The following charts and tables convert surface finish or roughness between selected industry standard units. Where: Ra = Roughness, average in micro-meters & micro-inches

You can calculate surface roughness by measuring the average surface peaks and valleys across that surface. The measurement is often seen as ‘Ra,’ which means ‘Roughness Average.’ In …

- Roughness is measured in a trasversal direction to the main grooves. - The mean arithmetical value “Ra” in μm is assumed for roughness measurements. -Rt: maximum value of roughness …
