Convert semester SGPA to a percentage. Uses the CBSE ×9.5 formula by default, with the other formula families Indian universities use, so you can match your own marksheet.
| Input | Result |
|---|---|
| 8.4 SGPA (CBSE ×9.5) | 79.8% (CBSE formula) |
| 7.8 SGPA (CBSE ×9.5) | 74.1% (CBSE formula) |
| 9.2 SGPA (CBSE ×9.5) | 87.4% (CBSE formula) |
| 6.5 SGPA (CBSE ×9.5) | 61.75% (CBSE formula) |
SGPA (Semester Grade Point Average) is the credit-weighted average of the grades you earned in one semester. CGPA (Cumulative Grade Point Average) aggregates every semester you have completed. The conversion formula is identical, but the numbers answer different questions: an SGPA of 8.4 describes one term, while the same 8.4 as a CGPA describes your entire transcript so far. If your question is about the degree as a whole, use the CGPA to percentage calculator instead.
There is no single national rule. The CBSE multiplier (×9.5) is the most common default, but universities that publish their own conversion will not accept a figure derived from someone else's formula:
| Formula | 8.0 SGPA converts to | Where you meet it |
|---|---|---|
| SGPA × 9.5 | 76% | CBSE boards and the majority of central universities, the usual default |
| SGPA × 10 | 80% | Institutions that map grade points directly to marks |
| (SGPA − 0.75) × 10 | 72.5% | Several state technical universities |
| SGPA × 9.3 | 74.4% | Some state universities, check your own examination circular |
Verify before you quote it. The spread between these families is 3–8 percentage points at the same SGPA. Universities also revise their formula between schemes, so the figure printed on your marksheet or in the current examination circular outranks every generic multiplier, including this one.
| SGPA | Percentage |
|---|---|
| 10.0 | 95% |
| 9.5 | 90.25% |
| 9.0 | 85.5% |
| 8.5 | 80.75% |
| 8.0 | 76% |
| 7.5 | 71.25% |
| 7.0 | 66.5% |
| 6.5 | 61.75% |
| 6.0 | 57% |
| 5.5 | 52.25% |
To combine several semesters into one cumulative figure first, use the SGPA to CGPA calculator; to turn a percentage back into a 10-point average, use the percentage to CGPA calculator.
Multiply your SGPA by 9.5 under the CBSE formula: an SGPA of 8.4 becomes 79.8%. If your university publishes its own multiplier, use that instead, the result can differ by several percentage points at the same SGPA.
The arithmetic is the same, the input is not. SGPA covers a single semester, CGPA covers all completed semesters. Converting an SGPA tells you how one term translated into marks; it says nothing about your cumulative standing.
Under the CBSE multiplier, 8.0 × 9.5 = 76%. A direct ×10 formula gives 80%, the (SGPA − 0.75) × 10 family gives 72.5%, and ×9.3 gives 74.4%. Pick the family your university prescribes before quoting a number.
Then the 9.5 multiplier does not apply, because it was derived from a 10-point maximum. A 4-point SGPA has to be converted to a 4.0 GPA first, see the 4.0 GPA scale page, and only then compared with percentages using your institution's published equivalence.
Only within the same formula, where the mapping is linear. Across two universities it can flip: an 8.2 SGPA under ×9.5 is 77.9%, while an 8.5 SGPA under the (SGPA − 0.75) × 10 rule is only 77.5%. That is why comparing percentages from two different institutions without checking their formulas is unsafe.
