Hi, try this:

mySimplify[f_] := Simplify[f, Assumptions -> {Meter > 0, Second > 0}]

Sqrt[Meter^2/Second^2]*Second/Meter^2 // mySimplify


Have fun, Alexei

Working with units I get correct result:

Sqrt[Meter^2/Second^2] Second)/Meter^2

   How to tell Mathematica to simplify the result to Meter^-1?
Simplify and FullSimplify doesn't do the job.
Thanks in advance,
