How to compare Uniques to Conversion


im sorry if this question is dumb or there is a easy way to do it, but I cant find a way currently.

Im looking for a way to track UNIQUE visitors per Conversions. I have set that click on a link counts as a manual Conversion and only one click per user will count (second click wont count), but Visitors are still shown as total visitors, not unique visitors - I need it to show unique, because otherwise I cant see real numbers and see skewed numbers for conversion rate.

Is it possible somehow?
