Questions
What is the formula to convert CGPA to percentage?
It depends on who awarded the CGPA. CBSE: 9.5 × CGPA. VTU: (CGPA − 0.75) × 10. Anna University (Regulations 2021): CGPA × 10. If your university is not listed, check its regulations or ask for a conversion certificate.
Why not just multiply by 9.5 for everyone?
Because universities publish different formulas. 9.5 × CGPA is CBSE's indicative formula for Class 10; VTU subtracts 0.75 first; Anna University's 2021 regulations use CGPA × 10. Using the wrong one can move the result by several percent, which matters for job and admission cut-offs.
Which universities are included?
Only those whose formula we could read on the university's or board's own website: CBSE, VTU and Anna University (R2021). Each result links to that source. Universities that have no published formula, or that now print percentages from marks (Mumbai University from January 2026), are left out rather than guessed.
Is the converted percentage official?
The formula is the university's own, but the percentage on your transcript or a conversion certificate issued by the university is what employers and admission offices accept. Use this to check before you apply.
