Converting CGPA to Percentage: A Complete Guide

Published on:


Converting Cumulative Grade Point Average (CGPA) to percentage can be a confusing task for many students. While both CGPA and percentage are widely used grading systems, their conversion may vary depending on the institution or country. This comprehensive guide aims to provide clarity on how to accurately convert CGPA to percentage and vice versa.

Understanding CGPA and Percentage

CGPA (Cumulative Grade Point Average)

CGPA is a grading system used by educational institutions to evaluate a student’s overall academic performance. It is calculated by averaging the grade points obtained in all subjects over a certain period, usually a semester or an academic year. The scale for CGPA typically ranges from 0 to 10, where 10 is the highest achievable grade.


Percentage, on the other hand, is a common method of grading based on a scale of 0 to 100. It represents the relative performance of a student in a specific course or overall academic record. In percentage grading, each subject is usually evaluated out of 100 marks, with a passing grade typically set at 40% or higher.

Converting CGPA to Percentage

Method 1: Using a Conversion Formula

One of the most common methods to convert CGPA to percentage is by using a conversion formula. The formula may vary depending on the institution, but a common approach is to multiply the CGPA by a certain factor to get the equivalent percentage. For instance, if the grading system follows a 10-point scale, the conversion formula could be as follows:

Percentage = CGPA x 9.5

This formula is derived from the standard conversion where 10 CGPA is considered equivalent to 100%, resulting in a conversion factor of 9.5.

Method 2: Using a Grading Table

Some institutions provide specific grading tables or conversion charts to facilitate the conversion process. These tables typically outline the equivalent percentage range for each CGPA value. Students can refer to these tables to determine their percentage based on their CGPA.

Method 3: Consulting With the Institution

If you are unsure about the conversion process or the specific formula to use, it is advisable to consult with your educational institution or academic advisor. They can provide you with the accurate conversion method as per the institution’s grading system.

Considerations for Conversion

  • It is essential to consider the grading scale used by your institution to ensure accurate conversion.
  • Some institutions may have specific guidelines or rounding off rules for converting CGPA to percentage.
  • In cases where the grading system is different, such as a 4-point scale, the conversion formula may vary accordingly.

Converting Percentage to CGPA

Method 1: Using the Inverse Conversion Formula

To convert percentage to CGPA, an inverse conversion formula can be used. The formula involves dividing the percentage by a specific factor to obtain the corresponding CGPA. For instance, if the grading scale follows a 10-point system, the formula can be represented as:

CGPA = Percentage ÷ 9.5

By dividing the percentage by 9.5, you can determine the equivalent CGPA based on the given percentage.

Method 2: Referring to Institution Guidelines

As with converting CGPA to percentage, it is recommended to refer to the specific guidelines provided by your institution for converting percentage to CGPA. Understanding the institution’s grading policy can help ensure accuracy in the conversion process.
