Anna University CGPA Calculation: Step-by-Step Guide

Anna University uses the following official formula for converting CGPA to percentage:

Percentage = CGPA × 10

This formula is specified in the Anna University academic regulations. You simply multiply your CGPA by 10 to get your percentage.

Here are sample conversions using Anna University's formula:

Anna University uses a 10-point grade scale:

SGPA (Semester Grade Point Average) is calculated at the end of each semester:

SGPA = Σ(Credit Points × Grade Points) / Σ(Credit Points)

For example, if you have 3 subjects with credits 4, 4, and 3, and grade points 9, 8, and 7:

SGPA = (4×9 + 4×8 + 3×7) / (4+4+3) = (36 + 32 + 21) / 11 = 89 / 11 = 8.09

CGPA is the weighted average of all SGPA values across all semesters, weighted by the number of credits in each semester:

CGPA = Σ(SGPA × Credits in Semester) / Σ(All Credits)

This means every semester's performance contributes to your final CGPA, proportional to the total credits undertaken in that semester.
