GPA or Grade Point Average is the method by which US universities evaluate the performance of their students in the examinations.
The range of GPA is from 0 to 4. It is not possible to convert your percentage score into GPA, as they are not linearly related.
For example, a percentage of 75 cannot be said to be equivalent to 3 out of 4.
Therefore, wherever you are asked to state your GPA, you should only enter your percentage score.
A rough equivalence of the percentage score multiplied by the GPA can be got as 4x x/85. For example, if your percentage score is 75, it is roughly equivalent to 4 x 75/85 =3000/85 = 3.53
