The official Anna University rule

Anna University converts CGPA to percentage with Percentage = CGPA × 10. It applies to: UG and PG programmes under Regulations R-2015, R-2018 and R-2019, and Regulations 2021 (clause 15.5.3). The rule is taken from Anna University – CGPA to Percentage Conversion, Office of the Additional Controller of Examinations (University Departments) ↗ — open that official document and you will find the same formula; we never copy conversion rules from other calculator websites.

How to convert, step by step

First, take your exact final CGPA from your consolidated grade card, without rounding it. Second, confirm the scheme, ordinance or graduation-year version that governs your batch — if this page's calculator shows a version selector, choose yours. Third, enter the CGPA above and apply the official equation exactly as written. Fourth, when you report the percentage anywhere official, name the rule beside it (for example, “as per Anna University – CGPA to Percentage Conversion, Office of the Additional Controller of Examinations (University Departments)”) so the figure can be checked. If you still need the CGPA itself, build it from semester SGPAs with the SGPA to CGPA calculator first. The general method is also explained in our guide on how to convert CGPA into percentage.

Good to know

Anna University's conversion is one of the simplest in India — a flat multiplier with no deduction. Older calculator sites sometimes show (CGPA − 0.5) × 10 for Anna University; that offset belongs to other universities and is not in Anna University's ACOE conversion letter or its Regulations 2021, both of which state Percentage of Marks = CGPA × 10.
