Enter your values, select your grading scale, and get your CGPA along with your percentage, division, and status right away.

What is SGPA and CGPA?

Before jumping into the conversion, it is important to understand what these two terms actually mean and how they are different from each other.

What is SGPA?

SGPA stands for Semester Grade Point Average. It is a number that represents your academic performance in a single semester. After every semester ends, your university calculates your SGPA based on the grades you earned in each subject and the credit hours assigned to those subjects.

Think of SGPA as your report card for one semester — it tells you how well you performed during that specific period of time.

What is CGPA?

CGPA stands for Cumulative Grade Point Average. It is the overall average of all your SGPAs across every semester you have completed so far. While SGPA gives you a picture of one semester, CGPA gives you the complete picture of your entire academic journey up to that point.

CGPA is the number that appears on your final degree certificate and is used for job applications, university admissions, and scholarship eligibility.

Difference Between SGPA and CGPA

What is the Formula to Convert SGPA to CGPA?

There are two formulas depending on whether all your semesters carry equal credits or different credits.

Simple Average Formula (Equal Credits)

If all your semesters carry the same number of credits, the formula is straightforward:

CGPA = Sum of all SGPAs ÷ Total Number of Semesters

Example: If your SGPAs across 4 semesters are 7.5, 8.0, 8.5, and 9.0:

• CGPA = (7.5 + 8.0 + 8.5 + 9.0) ÷ 4
• CGPA = 33.0 ÷ 4 = 8.25

Weighted Average Formula (Unequal Credits)

If different semesters carry different credit hours, use the weighted average formula:

CGPA = Sum of (SGPA × Credits) ÷ Total Credits

Example:

• CGPA = (7.5×20) + (8.0×22) + (8.5×20) + (9.0×18) ÷ (20+22+20+18)
• CGPA = (150 + 176 + 170 + 162) ÷ 80
• CGPA = 658 ÷ 80 = 8.225

How to Use This SGPA to CGPA Calculator

Our calculator has two modes — Semester-wise and Quick Calculate. Here is exactly how to use both.

Method 1 – Semester-wise Mode

This mode is for students who want to enter each semester’s SGPA individually and get a detailed breakdown.

1. Select Semester-wise tab at the top of the calculator
2. Select your Grading Scale — choose from 10.0, 4.0, or 5.0 Scale
3. Enter your SGPA for Sem 1 in the first input field
4. Click “+ Add Semester” to add more semester rows
5. Enter SGPA for each remaining semester — Sem 2, Sem 3, Sem 4 and so on
6. Click “Calculate CGPA ⚡” button
7. View your result showing four things:
   
   • Your CGPA (e.g., 8.25 out of 10.0)
   • Your Percentage (e.g., 78.37%)
   • Your Division (e.g., 1st Division)
   • Your Status (e.g., ✓ Pass)
8. Check the Formula shown below the result
9. View the Semester Breakdown Table showing each semester individually

Method 2 – Quick Calculate Mode

This mode is for students who already know the sum of all their SGPAs and just want a fast result.

1. Select Quick Calculate tab at the top of the calculator
2. Select your Grading Scale — 10.0, 4.0, or 5.0
3. Enter the Sum of All SGPAs in the first input field (e.g., 8.7)
4. Enter the Number of Semesters in the second input field (e.g., 5)
5. Click “Calculate CGPA ⚡” button
6. View your result — CGPA, Percentage, Division, and Status
7. Check the Formula below the result

SGPA to CGPA Conversion – Solved Examples

Example 1 – Equal Credits Across Semesters

• Step 1: Add all SGPAs → 8.0 + 7.5 + 8.5 + 9.0 = 33.0
• Step 2: Divide by total semesters → 33.0 ÷ 4 = CGPA 8.25
• Step 3: Convert to percentage → 8.25 × 9.5 = 78.37%

✅ Result: CGPA 8.25 → Percentage 78.37% → 1st Division → Pass

Example 2 – Unequal Credits Across Semesters

• Step 1: Multiply each SGPA by credits → (7.0×18) + (7.5×20) + (8.0×22) + (8.5×20) = 126 + 150 + 176 + 170 = 622
• Step 2: Add total credits → 18 + 20 + 22 + 20 = 80
• Step 3: Divide → 622 ÷ 80 = CGPA 7.775
• Step 4: Convert to percentage → 7.775 × 9.5 = 73.86%

✅ Result: CGPA 7.775 → Percentage 73.86% → 1st Division → Pass

SGPA to CGPA Reference Table

This table shows the approximate CGPA for common SGPA values when all semesters have equal credits — based on the 10-point scale.

⚠️ Note: This table assumes all semesters carry equal credit hours. For unequal credits, use the weighted average formula or Semester-wise mode above.

SGPA to Percentage Conversion Table

This table directly shows what percentage your SGPA corresponds to on the 10-point scale using the standard formula: SGPA × 9.5 = Percentage.

📌 Formula Used: SGPA × 9.5 = Percentage

Common Mistakes to Avoid When Converting SGPA to CGPA

1. Using Simple Average When Credits Are Unequal — The biggest mistake students make is dividing the sum of all SGPAs by the number of semesters when each semester has different credit hours. If your credits are not equal, always use the weighted average formula.
2. Rounding Off Too Early — Rounding your SGPA or intermediate values before reaching the final answer leads to noticeable errors. Always keep full decimal values until the very last step.
3. Ignoring Failed or Repeat Subjects — If your grading system includes failed subjects in the SGPA, they must also be included in the CGPA calculation. Leaving them out gives you an inflated CGPA that does not match your official record.
4. Using the Wrong Grading Scale — Always confirm whether your university uses a 10-point, 4-point, or 5-point scale before calculating. Using the wrong scale will give you a completely inaccurate result.
5. Confusing SGPA Sum with CGPA — Some students add all their SGPAs together and think that is their CGPA. The sum of SGPAs must always be divided by the number of semesters to get CGPA.

Why CGPA Matters More Than SGPA

• Job Applications — Most companies and government organizations ask for your CGPA on application forms. A consistently strong CGPA signals that you performed well throughout your degree, not just in one semester.
• University Admissions — Postgraduate programs and foreign universities evaluate your overall CGPA for admission. A single good semester does not compensate for a weak overall CGPA.
• Scholarship Eligibility — Most scholarship programs have a minimum CGPA requirement. Knowing your accurate CGPA helps you identify which scholarships you qualify for.
• Academic Standing — Many universities have a minimum CGPA requirement to remain in good academic standing. Falling below this can lead to academic probation.
• Motivation and Goal Setting — When you track your CGPA after every semester, you can clearly see whether you are on the right path and adjust your study efforts accordingly.
