Semester Grade Summary
Why Use This GPA to SGPA Calculator?
Engineered for university students, academic advisors, international applicants, and registrars.
- Dual Scale Support (10.0 & 4.0 Systems): Seamlessly toggle between Indian/global 10-point SGPA scales and North American 4.0 letter grade GPA systems.
- Credit-Weighted Precision: Automatically factors in course credit hours as mathematical weights rather than treating all subjects as equal unweighted averages.
- Multi-Course Flexibility: Easily add or remove unlimited course rows with instant real-time quality point recalculations as you type.
- Instant Percentage Conversion: Automatically converts calculated SGPA/GPA to an exact percentage score using official board formulas (9.5× multiplier).
- High-DPI JPEG Exporter: Download a clean, high-resolution JPEG summary report card in one click to attach to scholarship applications or transcript logs.
- 100% Client-Side Privacy: All grade computations execute locally inside your web browser—no transcript data, course names, or grades are stored or uploaded remotely.
Understanding GPA vs. SGPA vs. CGPA
SGPA (Semester Grade Point Average) measures a student's credit-weighted academic standing for a single term or semester. CGPA (Cumulative Grade Point Average) reflects the combined weighted average across all completed semesters.
Because courses carry different academic loads (such as a 4-credit core subject versus a 1-credit lab), grades cannot simply be averaged together as a basic arithmetic mean. For single-course category weightings, try our dedicated Weighted Grade Calculator.
How Credit Weighting Works
Mathematical formula used to compute credit-weighted semester averages.
SGPA Formula
Sum of (Grade Points × Course Credits) divided by Total Semester Credits.
10.0 Scale % Conversion
Standard university conversion formula (CBSE / VTU / AICTE standard).
4.0 Scale % Conversion
Standard North American 4.0 GPA linear conversion scale.
Standard Letter Grade Scale Reference (4.0 System)
Reference mapping for letter grade point values
| Letter Grade | Grade Points (4.0 Scale) | Percentage Range |
|---|---|---|
| A+ / A | 4.0 | 90% – 100% |
| A- | 3.7 | 85% – 89% |
| B+ | 3.3 | 80% – 84% |
| B | 3.0 | 75% – 79% |
| B- | 2.7 | 70% – 74% |
| C+ / C | 2.0 – 2.3 | 60% – 69% |
| D / F | 0.0 – 1.0 | Below 60% |
Frequently Asked Questions
1. What is the difference between GPA and SGPA?
SGPA represents performance in one specific semester, while GPA/CGPA reflects cumulative performance across your entire academic program.
2. How are course credits factored into SGPA?
Course credits act as mathematical multipliers. A grade in a 4-credit course has double the influence on your final SGPA compared to a 2-credit course.
3. How do you convert SGPA to percentage on a 10.0 scale?
Most Indian universities (AICTE/VTU/Delhi University) use the standard formula: Percentage = SGPA × 9.5. For example, an 8.0 SGPA equals 76%.
4. Can I enter letter grades directly?
Yes. On the 4.0 scale option, you can select letter grades (A, B+, B, C, etc.) from the dropdown menu, and the calculator automatically maps them to numerical quality points.
