Accurate SGPA to CGPA Calculator
For Engineering (B.Tech), Arts, Science, and Management Students.
Calculating your Cumulative Grade Point Average (CGPA) is more complex than just taking the average of your semester results. Most universities (including KTU, VTU, Anna University, and CBSE) use a weighted average system where semesters with higher "Total Credits" have a larger impact on your final score. This tool handles that complexity automatically.
Weighted Calculation
We use the formula ∑(SGPA × Credits) / ∑(Credits). If you leave credits blank, we switch to a simple average mode automatically.
Percentage Converter
Instantly convert your final CGPA to Percentage using the standard 9.5x multiplier (or customize it for your specific university).
How to Calculate CGPA from SGPA
Where S is the SGPA of a semester and C is the Total Credits for that semester.
Why it matters: A score of 9.0 in a 24-credit semester is worth more than a 9.0 in a 18-credit semester.
Common Grading Scales
| Grade Point | Letter Grade | Performance |
|---|---|---|
| 10 | O / A+ | Outstanding |
| 9 | A+ / A | Excellent |
| 8 | A / B+ | Very Good |
| 7 | B+ / B | Good |
*Note: Grading scales vary by university (KTU, VTU, Mumbai University, etc.). Check your official mark list.
Frequently Asked Questions
What is the difference between SGPA and CGPA?
SGPA (Semester Grade Point Average) is your grade for a single semester. CGPA (Cumulative Grade Point Average) is the combined average of all your semesters up to that point, usually weighted by credit points.
Why do I need to enter Credit Points?
Credits represent the 'weight' or importance of a semester. A semester with more labs and subjects (e.g., 24 credits) contributes more to your final CGPA than a lighter semester (e.g., 18 credits). Using credits ensures your CGPA matches your university's official calculation.
How to convert CGPA to Percentage?
The formula is CGPA × Multiplier. For CBSE and many universities, the multiplier is 9.5. For example, a 9.0 CGPA equals 85.5% (9.0 × 9.5). Some technical universities use specific formulas like (CGPA - 0.75) × 10.
Can I simply average my SGPAs?
Only if every semester has the EXACT same total credits. If Sem 1 has 22 credits and Sem 2 has 24, a simple average (S1+S2)/2 will be incorrect. You must use the weighted average formula provided by this calculator.
How is CGPA calculated for engineering (KTU/VTU)?
Most engineering universities use the credit-weighted system: Sum of (SGPA × Credits) / Sum of Credits. This calculator follows that exact standard.
What is a good CGPA?
Generally, a CGPA above 8.0 is considered 'First Class with Distinction' in many Indian universities. Above 6.0 or 6.5 is usually 'First Class'. However, this varies widely by institution and country.
