Ahh ok I have found the equation thanks for helping. http://en.wikipedia.org/wiki/Area_density Also I guess I should know that all I have to do is look at the units to determine how to find the thickness. I must be not thinking straight today ! Cheers

Ok I am studying experimental physics and I wondering if you can determine the thickness of a target if you only know the area density. For example if you have a target of 70 micrograms/cm^2 can you determine the thickness from just this information ? I have tried to find equations but cannot...
