How it works

Formula: Percentage = (CGPA / Max CGPA) × 100

We use the scale you select to determine the maximum CGPA. For example, if you have a CGPA of 8.0 on a 10.0 scale, the percentage is (8.0 / 10.0) × 100 = 80%. The percentage is then mapped to a letter grade using a standard grading table.

Inputs explained

CGPA: Your Cumulative Grade Point Average (e.g., 8.0, 3.5).
CGPA Scale: The maximum CGPA possible in your grading system (10.0, 4.0, 5.0, or custom).
Custom Max CGPA: If your institution uses a different scale, enter the maximum value here.

Example

Input: CGPA = 8.0, Scale = 10.0
