Should I convert my GPA to the US 0-4 Scale in the Common App Section Grades?

In Austria where I am from 1 is the best grade and 5 the worst. So if I have a GPA of 1 in Austria, should I put 1.0 or 4.0 as my unweighted GPA for the college application? Thanks!!

No.

1.0

You should assume that the colleges to which you are applying have admissions officers who are well-versed in the grading systems in various countries.
