CGPA (Cumulative Grade Point Average) is a grading system used to assess a student’s academic performance. It represents the average of grade points earned across all subjects. CGPA is typically measured on a scale of 10, but some institutions use different scales. Converting CGPA into a percentage is essential for many academic and job-related applications, and understanding the general formulas helps students and professionals alike.

Standard Formula for CGPA to Percentage Conversion

The most commonly used formula for converting CGPA into a percentage is:

Percentage = CGPA × 9.5

For example, a CGPA of 8.5 would translate to: 8.5 × 9.5 = 80.75%

In some cases, a 4-point scale may be used, and the conversion formula would be:

Percentage = CGPA × 25

It’s essential to use the right conversion formula based on the grading system used.

How to Calculate CGPA from Percentage

To convert a percentage back into CGPA, the formula typically used is:

CGPA = Percentage ÷ 9.5

For example, if a student has a percentage of 85%, the corresponding CGPA would be:

85 ÷ 9.5 = 8.95

This formula ensures accurate representation of a student’s academic performance across different grading systems.

Examples of CGPA to Percentage Conversion

Example 1: Standard CGPA Scale (10.0)

Given: CGPA = 7.8
Conversion Formula: Percentage = CGPA × 9.5
Percentage = 7.8 × 9.5 = 74.1%

Example 2: CGPA Scale of 4.0

Given: CGPA = 3.6
Conversion Formula: Percentage = CGPA × 25
Percentage = 3.6 × 25 = 90%

These examples show how different scales are handled, ensuring students can convert their CGPA regardless of the system used.
