Roughness units conversion table

How the roughness unit in delta could be converted to microns?

Hello Emil!

First, you want to surf over to www.predev.com/smg/parameters.htm to make sure that your roughness unit is what you think it is. That website has a lot of information on how surface roughness is calculated and expressed.

Then you start with the conversion fact that there are 25.4 millimeters in one inch, which gives you 25.4 microns per 1000 microinches.

Good luck!
