How to Convert a Percentage into a 4.0 Grade Point Average

Step-by-Step Guide

1. 1

   Step 1: Know the formula for converting a percentage into a 4.0 GPA.

   Let's use x to represent the percentage.
   
   The formula to use when converting a percentage into a GPA (with a scale of
   4.0) is (x/20)
   - 1 = GPA. , Let's say you have an 89% in Geology.
   
   Just plug it into the formula to get the following: 89/20
   - 1 =
   4.45
   - 1 =
   3.45.
   
   The GPA equivalent of 89% is
   3.45. , The process will be the same even if your percentage is higher than 100%.
   
   Let's say you got a whopping 108% in Algebra.
   
   Here's what happens when you plug it in: 108/20
   - 1 =
   5.4
   - 1 =
   4.4 The GPA equivalent of 108% is
   4.4. , This may be useful depending on what you are calculating your GPA for.
   
   If you are calculating one grade at a time to see how they will add up for your high school GPA, then you may not have to follow this exact formula because all grades will fall within a range anyway.
   
   For example, if your grade falls within the range of 83-86, then depending on your high school, then you will have a B, or a
   3.0, whether it falls on the higher or lower part of the range or not.Check out your school's GPA system to figure out how to do this; some high schools have a slightly different range for what makes an A- vs. an A, a B vs. a B+, and so on.
