Should I include my converted GPA/final semester GPA on my CV? I'm applying to graduate school and I'm contacting potential supervisors, as advised by the universities I'm applying to.

My GPA is 16.33/20. When I convert it to the 4.0 scale,according to WES, my overall GPA, GPA in the final 2 years, the final year and the final semester are 3.41, 3.34, 3.4 and 4.0 respectively.

Does 3.41 look better than 16.33? As I want to make a good first impression, should I include my final semester GPA or does it simply highlight my poor performance in the previous semester?
Provide a copy of the original transcript(s) detailing all the grades.

Any university will convert the values according to their "rules" and evaluate your application as necessary.
