How to use it
- Choose the direction: CGPA → % or % → CGPA.
- Pick the formula your board or university uses — CBSE (× 9.5), × 10, VTU, or Custom to type the multiplier printed on your marksheet.
- Enter your CGPA (or percentage). The result and the formula with your numbers appear instantly, plus a quick chart for nearby values.
CGPA to percentage formulas
There is no single national formula. Each board or university decides its own, and many print it on the marksheet or in their ordinances. These are the most common ones, with a CGPA of 8.4 as the example:
| Used by | CGPA → % | CGPA 8.4 |
|---|---|---|
| CBSE (CCE scheme) | CGPA × 9.5 | 79.8% |
| Many universities | CGPA × 10 | 84% |
| VTU | (CGPA − 0.75) × 10 | 76.5% |
| Your university’s factor | CGPA × multiplier | e.g. × 9 = 75.6% |
Formulas can change between schemes and batches, so your marksheet or your university’s official notice is always the final word.
The CBSE 9.5 formula
Under CBSE’s Continuous and Comprehensive Evaluation (CCE) scheme, Class 10 results were given as grades and a CGPA instead of marks, and the marksheets of that period stated that an indicative percentage can be found by multiplying the CGPA by 9.5. CBSE has since gone back to showing marks, so this formula is mainly needed for older Class 10 results.
- CGPA 9.2 → 9.2 × 9.5 = 87.4%
- 85% → 85 ÷ 9.5 = 8.95 CGPA
Because 10 × 9.5 = 95, a CGPA of 10 works out to 95% under this formula, not 100%.
The VTU formula
Visvesvaraya Technological University (VTU) has used Percentage = (CGPA − 0.75) × 10 for converting its students’ CGPA. A CGPA of 8.0 becomes (8.0 − 0.75) × 10 = 72.5%, and the highest possible CGPA of 10 becomes 92.5%. Check the circular that applies to your scheme on the VTU website or with your college.
SGPA, CGPA and 4-point GPA
- SGPA is your grade point average for one semester.
- CGPA is the credit-weighted average of all semesters so far — this is the number usually converted for forms.
- A 4-point GPA (common abroad) has no single conversion to percentage, so this tool sticks to the 10-point scale used in India.
Using the percentage in forms
Many job and admission forms ask for both your CGPA and the equivalent percentage. Use the formula from your own university; if it has none, the form’s instructions sometimes specify one. Once you have the percentage, the percentage calculator can help with any other marks working you need.
