100% scale to 4.0 scale

TL;DR: You cannot directly convert 87% to a 4.0 scale.

87/100 could actually convert to a lot of different GPAs, depending on the grades you got in individual classes. Do you have a record of all your grades out of 100 from individual classes?

Take each individual grade out of 100 and assign it either 0, 1, 2, 3, or 4 “grade points” according to the following scale (unless your school gives out letter grades for classes, in which case you can use their scale):

94 - 100 = A = 4 points
85 - 93 = B = 3 points
74 - 84 = C = 2 points
65 - 73 = D = 1 point
0 - 64 = F = 0 points

This assumes every class you’ve taken is worth one credit. For half-credit classes, divide the number of points by two.

Now:

1. Add up all the grade points.

2. Divide this number by the number of credits attempted. If you’ve never failed a class, this is the same as the number of credits you’ve earned. If every class is worth one credit, this is the same as the number of classes you’ve taken throughout your high school career. This is your unweighted GPA.

Other stuff to note:

1. Important: Different high schools use different grading scales. I picked this one arbitrarily based on what my high school uses, and it’s one of the “stricter” ones I’ve seen.

2. Pass/fail classes (most people don’t have these, but just in case) don’t count toward your GPA.
