Job portals ask for percentage; your marksheet shows CGPA. For Anna University the arithmetic is simple — Percentage = CGPA × 10 — but some employers and foreign evaluators want that in writing. Here’s the full picture.
The formula (and where it’s stated)
Anna University regulations specify the CGPA × 10 equivalence — an 8.2 CGPA is 82%. Use it directly in application forms that accept self-declared percentages, and compute your CGPA precisely with the CGPA calculator.
When you need a conversion certificate
- Background verification: some employers want university-issued proof of the formula, not your arithmetic.
- Government forms/PSUs: often demand an official percentage-equivalence certificate.
- Foreign evaluations: WES and universities abroad may request the university’s stated conversion policy.
Getting it in writing
- Many marksheets/consolidated statements already print the conversion rule — check yours first; a copy of that page often suffices.
- Otherwise, a percentage-conversion certificate can be obtained through the university’s certificate services (route via your college office for the current procedure and fee).
- For forms with no certificate requirement, state “CGPA 8.2 (equivalent to 82% as per Anna University norms)” — the standard phrasing.
One warning
Never invent a different formula (like ×9.5 — that’s CBSE’s school formula, not Anna University’s). Inconsistent claims across applications are a background-verification red flag. One number, one formula, everywhere.
Frequently Asked Questions
How do I convert Anna University CGPA to percentage?
Multiply by 10 — a CGPA of 7.8 equals 78%. This is the equivalence stated in Anna University regulations and applies across R2017, R2021 and R2025.
What is a CGPA conversion certificate?
A university-issued document stating the official CGPA-to-percentage formula, required by some employers, PSUs and foreign credential evaluators. If your marksheet already prints the conversion rule, a copy of it is often accepted.
Is the ×9.5 formula applicable to Anna University?
No — ×9.5 is CBSE’s Class 10/12 convention. Anna University’s official equivalence is CGPA × 10; using any other multiplier creates inconsistencies in verification.
