How to Convert CGPA into Percentage? Simple Methods Explained

Many universities and boards in India use CGPA (Cumulative Grade Point Average) to evaluate academic performance. However, students and professionals often need to convert CGPA into percentages.

Whether you're applying for higher studies or a government job or are just curious, knowing how to convert CGPA into a percentage is important. Let’s break it down in a simple and easy-to-understand way.

How to Calculate CGPA

What is CGPA?

CGPA stands for Cumulative Grade Point Average. It’s a grading system used by many schools, colleges, and universities in India and abroad. This method calculates your overall academic performance based on grade points instead of raw marks.

CGPA is calculated over a specific period, such as a semester or an academic year. It considers the grade points you earned in all subjects and averages them. Instead of dealing with marks in each subject, you get a single number — your CGPA.

This system helps reduce pressure on students and brings uniformity in evaluation.

What is Percentage?

Percentage is the most common way to represent marks in India. It shows the ratio of marks obtained to the total marks, multiplied by 100. For example, if you scored 450 out of 500, your percentage would be 90%.

Most competitive exams, job applications, and university forms still ask for marks in percentage format. Even if your institution awards CGPA, you might need to convert it.

That’s why understanding how percentages work is essential.

What is the Difference Between CGPA and Percentage?

CGPA and percentage are both ways to measure performance, but they differ in approach. CGPA uses grade points. Percentage uses actual marks. Each has its benefits.

Here’s a simple table to understand the difference:

Factor CGPA Percentage
Full Form Cumulative Grade Point Average -
Scale Usually, out of 10 Out of 100
Units Grade Points Percentage (%)
Used By CBSE, universities Traditional schools, exams
Format Numerical (e.g., 8.5) Percentage (e.g., 85%)
Conversion Required Yes, for admissions or jobs No conversion needed
Interpretation Indicates overall academic strength Shows exact score

Common Conversion Methods (With Formulas)

Not all institutions use the same method to convert CGPA into a percentage. It's important to follow the correct formula as per your board or university guidelines.

Here are some of the most common formulas used:

1. CBSE Conversion Formula

CBSE uses a simple formula:

Percentage = CGPA × 9.5

Example:
If your CGPA is 8.0, then:
8.0 × 9.5 = 76%

2. Delhi University Formula

Some DU colleges follow this formula:

Percentage = (CGPA - 0.75) × 10

Example:
CGPA = 8.2
(8.2 – 0.75) × 10 = 74.5%

3. Mumbai University Formula

Mumbai University uses:

Percentage = CGPA × 7.1 + 11

Example:
CGPA = 7.5
7.5 × 7.1 + 11 = 64.25%

4. Anna University and Others

Some universities provide tables or ranges instead of formulas. Always check official documentation.

5. General Formula

Percentage ≈ CGPA × 10

This is a rough estimate and should not be used for official purposes.

How to Convert CGPA into Percentage?

Converting CGPA into a percentage might sound technical, but it's quite easy once you know the steps. Most universities provide a specific formula to help students do the conversion accurately.

Here’s a step-by-step guide to help you convert your CGPA into a percentage correctly:

Step 1: Find Out Your CGPA

Start by checking your latest mark sheet or academic transcript. Most universities and boards mention your CGPA. It is usually a number between 0 and 10. In some cases, especially with international systems, it may be on a 4-point scale.

Example: Your CGPA might be 8.2 out of 10.

Step 2: Know Your University’s Official Formula

This is the most important step. Every board or university may use a different formula for conversion. Using the wrong formula can give you incorrect results.

Here are a few common ones:

  • CBSE Formula: Percentage = CGPA × 9.5
  • Delhi University Formula: Percentage = (CGPA – 0.75) × 10
  • Mumbai University Formula: Percentage = CGPA × 7.1 + 11
  • Generic Formula: Percentage = CGPA × 10 (use this only when your institution has not given a formula)

Check your university website, guidelines, or student handbook to find the accurate formula.

Step 3: Apply the Formula

Once you have the correct formula, plug your CGPA into it.

Example (Using CBSE Formula):
If your CGPA is 8.2,
Percentage = 8.2 × 9.5 = 77.9%

Double-check your multiplication to avoid mistakes. You can use a calculator or spreadsheet to make it easier.

Step 4: Write Down or Mention the Formula Used

If you're adding your percentage to a resume, college application, or job form, it’s a good idea to mention the formula used for conversion.

Example:
"Converted using CBSE formula: CGPA × 9.5"

This provides clarity and avoids confusion for evaluators who may want to verify your data.

Step 5: Round Off Carefully (If Required)

Some institutions allow rounding to the nearest whole number, while others require exact decimals. Always follow the guidelines given.

Example:
77.9% may be rounded to 78% (if allowed).

Step 6: Store the Details Safely

Once you’ve calculated the percentage, save it somewhere safe. You might need it multiple times in the future for filling out forms or applying for competitive exams or jobs.

Why Convert CGPA to Percentage?

Many institutions in India still ask for marks in percentage format. Even if your university gives CGPA, you may have to convert it.

Here are some common reasons:

  • Higher Education: Many colleges, especially abroad or in competitive exams, require percentages.
  • Government Exams: Several exams have minimum percentage criteria.
  • Job Applications: Recruiters often ask for academic records in percentage format.
  • Scholarships: Some scholarships have cut-offs based on percentage, not CGPA.

Hence, converting your CGPA is often necessary to meet eligibility criteria or match standard formats.

  • Ignoring university-specific instructions.
  • Submitting an approximate percentage as official data.
  • Forgetting to mention the formula used in resumes or forms.
