Frequently asked questions
What is the Anna University CGPA to percentage formula?
Anna University ACOE official circular: Percentage = CGPA × 10. Applicable to all UG and PG engineering programmes under Anna University's affiliated college system.
Is this the official Anna University formula?
Yes — it's taken directly from Anna University's own published circular, not estimated or averaged from a generic multiplier. Using the wrong formula (for example, assuming a flat ×9.5 multiplier when your university uses a different one) can misstate your percentage by several points on official documents.
How do I convert percentage back to CGPA?
Switch to "Percentage → CGPA" mode above — it reverses the same Anna University formula correctly, including undoing any offset, not just dividing by a multiplier.
Can I use this for other universities too?
Yes — use the "University / board" dropdown in the calculator to switch to CBSE, Delhi University, Anna University, Mumbai University, VTU, or enter your own custom multiplier.
