CGPA to Percentage

Grading schemes differ greatly in the educational field, which frequently causes difficulty for professionals and students trying to compare and comprehend their academic performance. The Cumulative Grade Point Average is one of the most widely utilised grading schemes in use today (CGPA). Despite being widely used in many schools, CGPA is not always easy to understand, particularly when you need to convert it to a metric that is more widely accepted, such as a %. We will explore the complexities of converting CGPA to percentage in this extensive guide, outlining what CGPA is, why it’s used, and how to convert it to a percentage.

Understanding CGPA

What is CGPA?

Educational institutions, particularly in North America, employ the Cumulative Grade Point Average (CGPA) grading system to evaluate a student’s academic performance. The CGPA Calculator uses a scale that normally ranges from 0.0 to 4.0, in contrast to a percentage-based system where grades are represented on a scale from 0 to 100.

A student’s performance is assessed in each subject individually for the CGPA, and a grade of 4.0 is given to each course. After that, the cumulative GPA for the full academic programme is determined using these grades. Higher education institutions frequently use the CGPA as a standard method of evaluating student achievement, especially in the US and Canada.

How is CGPA Calculated?

You must first comprehend the grading scheme used at your school in order to compute your CGPA. The following grades are typically included in the 4.0 grading scale:

  • A (Excellent): 4.0
  • A- (Very Good): 3.7
  • B+ (Good): 3.3
  • B (Satisfactory): 3.0
  • B- (Satisfactory): 2.7
  • C+ (Adequate): 2.3
  • C (Adequate): 2.0
  • C- (Adequate): 1.7
  • D (Poor): 1.0
  • F (Fail): 0.0

Your performance in each course determines the mark you receive for that particular subject. Finding the weighted average of all your course grades—whose weight is based on the credit hours of each course—is necessary to compute your CGPA. The basic formula for calculating CGPA is as follows:

CGPA = (Σ(Grade Points * Credit Hours)) / Total Credit Hours

  • Σ: The summation symbol denotes that all of the course values should be added together.
  • Grade Points: The number that corresponds to your grade (A=4.0, B=3.0, etc.) on a 4.0 scale.
  • Credit Hours: The quantity of hours allotted to the course, signifying its proportional importance.

You can compute your CGPA by entering the grade scores for each of your courses together with the corresponding credit hours into this formula.

Why Convert CGPA to Percentage?

Even though the CGPA is a commonly used grading scheme, a lot of businesses and educational establishments still favour using the percentage approach to evaluate students. This choice is made for a number of reasons:

Global Standardisation: Employers and foreign institutions will find it simpler to assess your academic success using the % method since it is more widely recognised and accepted.

Comparability: The percentage method makes it simpler to compare students who have studied under various grading schemes, guaranteeing fairness in employment and admissions processes.

Certain Requirements: Converting from CGPA to percentage is crucial because certain organisations or jobs may have certain percentage-based requirements for employment, scholarships, or qualifying.

Transparency: For those who might be interested, the percentage system gives a clear picture of your academic performance.

For these reasons, understanding how to convert your CGPA to a percentage is an important skill, particularly if you intend to apply to universities or jobs in companies that have percentage-based hiring requirements.

Methods for CGPA to Percentage Conversion

There is no one-size-fits-all method for converting CGPA to percentage because different institutions and geographical areas may have different scales and methods for doing so. The following are a few of the most popular techniques:

1. Direct Conversion Method

The direct conversion method is the most straightforward way to convert CGPA to a percentage. It involves a simple linear conversion of CGPA to a percentage scale. However, it’s essential to note that the conversion factors may vary based on the educational institution or country.

Here is a basic formula for the direct conversion method:

Percentage = (CGPA / 4.0) * 100

CGPA: Your Cumulative Grade Point Average.

4.0: The maximum CGPA achievable in the 4.0 scale.

100: The maximum percentage score.

Using this formula, you can quickly convert your CGPA to a percentage. For example, if your CGPA is 3.2, the percentage would be:

Percentage = (3.2 / 4.0) * 100 = 80%

It’s important to check with your educational institution or potential employer to ensure they accept this method of conversion. Some institutions may use a slightly different scale, such as 4.33 or 5.0, in which case you would need to adjust the formula accordingly.

2. Grade Points to Percentage Method

In this method, you convert each CGPA point to a specific percentage range, often using a predefined table. The conversion table is usually established by the institution and may differ from one place to another. Here’s a basic example of such a conversion table:

  • 4.0 CGPA: 95-100%
  • 3.7 CGPA: 85-94%
  • 3.3 CGPA: 75-84%
  • 3.0 CGPA: 65-74%
  • 2.7 CGPA: 55-64%
  • 2.3 CGPA: 45-54%
  • 2.0 CGPA: 35-44%
  • 1.7 CGPA: 25-34%
  • 1.0 CGPA: 15-24%
  • 0.0 CGPA: 0-14%

Using this table, you can directly convert your CGPA into a percentage range. For instance, if your CGPA is 3.3, your percentage would fall in the 75-84% range. While this method is relatively easy to use, it is not as precise as the direct conversion method, as it relies on predefined ranges.

3. Custom Conversion Tables

Custom conversion tables may be created by certain employers or educational institutions in accordance with their unique needs and grading schemes. In these situations, you will have to follow their recommended conversion procedures. To find out the precise conversion criteria, it is imperative that you speak with the institution or organisation.

Factors Affecting CGPA to Percentage Conversion

It’s critical to realise that there are a number of variables that can affect the CGPA to percentage conversion. The following are some essential components that can affect the conversion process:

1. Scale of Grading

Grading scales used by various institutions and geographical areas may differ. As an illustration, although some institutions may employ a 5.0 scale, others may use a 4.33 or 4.0 scale. Since each grading scale has a different maximum CGPA and percentage value, the choice of scale can have a big impact on the CGPA to percentage conversion. To ensure an accurate conversion, always make sure you are aware of the exact grading scale your institution uses.

2. CGPA: Weighted versus Unweighted

Certain courses or semesters may be given more weight than others when calculating CGPA in some educational systems. When converting to a percentage, you should take into account whether your CGPA is weighted. A more thorough computation is needed for a weighted CGPA, which accounts for the relative significance of various terms or courses.

3. Acceptance of Conversion Method

Diverse CGPA to percentage conversion techniques may be accepted by various organisations, employers, or institutions. It is imperative to confirm the preferred or necessary method with the relevant entity. This guarantees that, when necessary, you will offer the most accurate and suitable conversion.

4. Special Conditions

Certain employers or institutions may have percentage-based requirements for employment, scholarships, or admission. To accurately meet the entity’s criteria, you should always adhere to their requirements.

5. Empirical Instances

Let’s look at a few real-world examples using the direct conversion method to better demonstrate the CGPA to percentage conversion procedure.

Example 1

Suppose you have a CGPA of 3.5 on a 4.0 scale. To convert this CGPA to a percentage using the direct conversion method, you can use the following formula:

Percentage = (CGPA / 4.0) * 100

Percentage = (3.5 / 4.0) * 100 = 87.5%

So, a CGPA of 3.5 on a 4.0 scale is equivalent to 87.5% using the direct conversion method.

Example 2

Let’s consider a different scenario where you have a CGPA on a 5.0 scale. If your CGPA is 4.2 on a 5.0 scale, you can apply the same direct conversion formula, taking the maximum CGPA value for the 5.0 scale, which is 5.0:

Percentage = (CGPA / 5.0) * 100

Percentage = (4.2 / 5.0) * 100 = 84%

CGPA of 4.2 on a 5.0 scale is equivalent to 84%.


For professionals and students wishing to satisfy employer or educational institution requirements and bridge the gap between various grading systems, converting CGPA to a percentage is a necessary step. Even though the direct conversion method is the most popular and simple, it’s important to take into account things like the grading scale, weighted versus unweighted CGPA, and the particular requirements of the organisation you’re working with.

Knowing how to convert a CGPA to a percentage makes it possible for you to showcase your academic accomplishments in a way that is widely acknowledged and accepted. This will facilitate your ability to apply for jobs, pursue additional education, and take advantage of other global academic and professional opportunities.

Never forget to confirm that you are using the appropriate conversion method and criteria by getting in touch with your educational institution, potential employers, or any other entities you may be dealing with. Precise conversion of CGPA to percentage is essential for creating a good first impression and fulfilling requirements in your academic and career path.
