How SGPA becomes CGPA

Equal weight: CGPA = (SGPA₁ + SGPA₂ + … ) / number of semesters
Credit-weighted: CGPA = Σ(SGPA × credits) / Σ(credits)
Percentage = CGPA × 9.5
Example. Semesters with SGPA 8.0, 7.5 and 9.0 (equal credits) give (8.0 + 7.5 + 9.0) ÷ 3 = 8.17 CGPA → 77.6%.

Frequently asked questions

How do I convert SGPA to CGPA?
If all semesters carry equal weight, CGPA is the simple average of your semester SGPAs: add all SGPAs and divide by the number of semesters. If semesters have different total credits, weight each SGPA by its credits: CGPA = Σ(SGPA × semester credits) ÷ Σ(credits).
Is CGPA just the average of SGPAs?
Yes, when every semester has the same total credits, CGPA is simply the average of all your SGPAs. When credit loads differ, use the credit-weighted average instead.
How do I convert the CGPA to percentage?
Use the UGC formula Percentage = CGPA × 9.5. Some universities use a different multiplier — see our CGPA to percentage tool.
