functions How Percentage to Grade Conversion Works

The Indian university grading system converts percentage marks to letter grades based on defined ranges. Beyond the letter grade, your percentage can also be expressed as a GPA on the 4.0 scale (used internationally) and a CGPA on the 10.0 scale (used in most Indian universities).

GPA Formula (4.0 Scale)

GPA = % ÷ 25

e.g. 80% ÷ 25 = 3.20 GPA

CGPA Formula (10.0 Scale)

CGPA = % ÷ 9.5

e.g. 80% ÷ 9.5 = 8.42 CGPA
