SGPA to CGPA Conversion Calculator

This SGPA to CGPA Calculator makes it easy to convert your semester GPA (SGPA) into your cumulative GPA (CGPA). Just enter your SGPAs and credits, and the calculator instantly shows your overall CGPA using the standard credit-weighted formula. It’s the fastest way to understand where you stand academically across all semesters.

SGPA vs CGPA: Key Differences

Let’s quickly clear up the difference between SGPA and CGPA so you know exactly what you’re converting.

• SGPA (Semester GPA): Think of it as your “semester scorecard.” It measures just one term and shows whether you’re improving or slipping compared to the last semester.

• CGPA (Cumulative GPA): This is your “career scoreboard.” It averages all semesters together and is the number that shows up on transcripts, resumes, and grad school apps.

• How they connect: Every SGPA you earn adds to your CGPA. A strong semester can pull your CGPA up, while a weak one can drag it down.

Factor	SGPA (Semester GPA)	CGPA (Cumulative GPA)
Full Form	Semester Grade Point Average	Cumulative Grade Point Average
Scope	One semester only	All semesters combined
Formula Used	Total grade points in a semester ÷ total semester credits	Σ(SGPA × Credits) ÷ Σ(Credits)
Purpose	Shows performance for one term	Shows overall academic performance
Frequency	Calculated at the end of each semester	Updated each term; finalized at graduation
Use	Track semester progress	Graduation score, placements, higher studies

In short – SGPA is one snapshot. CGPA is the full movie.

How to Use the SGPA to CGPA Calculator

1. Enter your details – Add your SGPA values (and credits, if required).
2. Choose your scale – Select 4.0, 10.0, or your school’s system.
3. Calculate your result – Click the button to see your CGPA and percentage instantly.

The calculator handles all the math automatically. You don’t need to calculate anything by hand — but here’s the exact formula it uses so you know how your CGPA is computed:

CGPA Formula

CGPA = Σ (SGPA × Semester Credits) ÷ Σ (Semester Credits)

This ensures semesters with more credits have a bigger impact on your final CGPA — exactly how universities compute it.

SGPA to CGPA Calculation Example

This example simply shows how credit-weighted averaging works.

Semester	SGPA	Credits
1	8.2	20
2	7.9	22
3	8.5	20
4	8.0	18

Step 1: Multiply each SGPA × credits

• 8.2 × 20 = 164
• 7.9 × 22 = 173.8
• 8.5 × 20 = 170
• 8.0 × 18 = 144

Total grade points = 651.8

Step 2: Add total credits

20 + 22 + 20 + 18 = 80

Step 3: Divide

651.8 ÷ 80 = 8.15 CGPA

Common Mistakes When Converting SGPA to CGPA

Mistake	Why It’s Wrong	Correct Approach
Averaging SGPAs directly	A simple average ignores credit differences between semesters.	CGPA must be a credit-weighted average. The calculator handles this automatically.
Ignoring different credit loads	A semester with more credits should impact CGPA more than a lighter semester.	Enter semester credits so the calculator weights each SGPA correctly.
Rounding each SGPA too early	Early rounding can distort final CGPA.	Only round after calculating the final CGPA (calculator already does this).
Mixing CGPA with GPA (4.0 scale)	These systems use different scales (10-point vs 4-point). Mixing them gives wrong results.	Keep SGPA/CGPA on the same scale unless converting with official formulas.
Forgetting to include backlogs or retakes	Depending on university rules, retake grades may replace or average into CGPA.	Always enter the SGPA your university records as final for that semester.
Using unverified online formulas	Many sites show incorrect or oversimplified formulas.	This calculator uses the standard credit-weighted method used by universities.

CGPA vs GPA Comparison

Now that you know the difference between SGPA and CGPA, it’s also helpful to understand how CGPA compares to the GPA system used in many countries, especially the U.S. and Canada. Students applying abroad often need to convert CGPA into GPA, and the two systems work differently. Here’s a quick comparison to make it clear.

Factor	CGPA	GPA
Scale	Often 10-point (India), sometimes 7-point	Typically 4.0 scale
Used In	India, Nepal, UAE, Asian universities	USA, Canada, some international colleges
Input Type	Based on SGPAs	Based on letter grades (A, B, C)
Method	Weighted average of all semesters	Weighted average of all courses
Purpose	Academic performance across program	Admissions, scholarships, academic standing

CGPA to Percentage Conversion

Some schools report grades as percentages instead of CGPA grade points, and many applications (jobs, scholarships, study abroad) ask you to convert. The exact formula can vary by institution, but here are the most common methods:

10.0 Scale

SGPA / CGPA	Percentage
10.0	100%
9.0	90%
8.0	80%
7.0	70%
6.0	60%

4.0 Scale

SGPA / CGPA	Percentage
4.0	100%
3.0	75%
2.0	50%
1.0	25%
0.0	0%

📌 Note: Always check your university’s official conversion policy.

CGPA and Percentage Conversion Examples

Example 1: 10-Point Scale, Equal Credits

This example shows how CGPA is calculated when all semesters have the same credit load.

Step	What Happens	Result
1	Add all SGPAs	8.5 + 9.0 + 8.8 = 26.3
2	Divide by number of semesters	26.3 ÷ 3 = 8.77
3	(Optional) Convert CGPA to percentage using ×10	8.77 × 10 = 87.7%

Final Result: CGPA = 8.77 (≈ 87.7%)

Example 2: 4-Point Scale, Varying Credits

This example shows the credit-weighted method used by all universities — and by your calculator.

Step	What Happens	Result
1	Multiply each SGPA by its semester credits	(3.2 × 15) + (3.5 × 18) = 48 + 63 = 111
2	Divide by total credits	111 ÷ (15 + 18) = 111 ÷ 33 = 3.36
3	(Optional) Convert CGPA to percentage using ×25 (4-point scale) or ×10 (10-point scale)	3.36 × 25 = 84%

Final Result: CGPA = 3.36 (≈ 84%)
