How to convert GPA to percentage
There is no single universal formula to convert GPA to percentage, as different countries and schools use different conversion methods.
For example, in the United States, a standard linear formula is often used (e.g., GPA / 4.0 * 100), but credential evaluators like WES use non-linear tables where specific grade thresholds map to specific percentages.
Converting Indian CGPA to percentage
In India, CBSE and many universities (like Mumbai University or Delhi University) use a multiplication factor. For CBSE, the standard formula is CGPA * 9.5 to estimate percentage. GradeAtlas automates these calculations for both directions.

Frequently asked questions
How do I convert a 4.0 GPA to percentage?
A common formula is Percentage = (GPA / 4.0) * 100. However, many schools map letter grades to specific percentage ranges (e.g., A = 90-100% = 4.0).

Using the standard CBSE formula (CGPA * 9.5), a 7.5 CGPA converts to 71.25%.
How do credential evaluators convert percentage to GPA?

What is 80% as a GPA?
On a standard US scale, an 80% is a 'B', which corresponds to a 3.0 GPA.
Why does CBSE use a 9.5 factor?
The 9.5 multiplier was derived by CBSE by analyzing the marks distribution of students in previous board examinations, balancing the score distribution.
Is GPA to percentage conversion official?
