I think this is a simple question.  I have a gear train that has an input rad/s and an output rad/s.  I need the output speed graph to read in mm/s.  Basically I just need to multiply the rad/s by 2(Pi) to get rps and then multiply the rps by 2(pi)r to get mm/s.

I'm a university student trying to solve a problem, we've been given a very little maplesim knowledge, mostly gear related.  If someone can help me make a custom probes or plots that would be appreciated.
