Percentage to GPA Conversion Formulas

Raghuram Sukumar —  September 12, 2008

I have written extensively about Percentage to GPA Conversion. I strongly suggest, you should read the GPA Converter before reading rest of this article.

I have received so many queries about how to convert Percentage to GPA and CGPA to GPA. I’m not a big fan of GPA conversion, but just to know what ideas different students have and how they convert their percentage score to GPA. I searched around to see what I can find about converting percentage to GPA. Here are some of the formulas used by students

Percentage to GPA – Formula 1

92-100 = 4.0 (A)

90-92 = 3.7 (A-)

87-89 = 3.3 (B+)

82-87 = 3.0 (B)

80-82 = 2.7 (B-)

77-79 = 2.3 (C+)

72-77 = 2.0 (C)

70-72 = 1.7 (C-)

Formula 2

Divide by 100 and multiply by 4.

Example : Percentage = 80, then GPA = 80 divided by 100 and multiply by 4.

Formula 3

Same as Formula2, but its simple. Divide Percentage by 4 to get GPA.

Percentage to GPA – Formula 4

70 -100 = 4.0 (A)

60 – 70 = 3.0 (B)

50 – 60 = 2.0 (C)

40 to 50= 1.0 (D)

Less than 40 = F

Comment from Yale University Admission Officer

I strongly suggest not to use convert percentage score to GPA using any of the formulas. When student asked about converting percentage to GPA, Yale University Admission officer, responded

No need for you to convert. We ask for your gpa and also the scale. You would just report the 78 and a scale of 10

In the graduate school application, you will find

  • What is your GPA:
  • Scale :

If you have 77% then you will need to fill the application

  • What is your GPA: 77
  • Scale :100
