⚠️ Universities use different formulas. Check the back of your marksheet or your university's rules, and use that formula on job and admission forms.
💡 Good to know
- CBSE's rule is percentage ≈ CGPA × 9.5 (based on its own past results).
- Many job forms (including some government ones) ask for the formula your university uses, and some want a certificate from the university.
- If your marksheet already shows a percentage, use that instead.

Which formula does my university use?+
It differs: common ones are CGPA × 10 and (CGPA − 0.75) × 10, and some universities use their own. Look on the back of your marksheet or on your university's website, then choose "My university's formula" if it isn't listed.
