CGPA (Cumulative Grade Point Average) and percentage scores are widely used for evaluating students, but different institutions and countries often favor one system over the other. If you’re planning to study abroad or apply to an institution that requests percentage scores, it’s essential to understand how to convert your CGPA into a percentage. This guide provides step-by-step instructions on CGPA-to-percentage conversions for different grading systems (10, 5, and 4-point scales), along with a quick calculator for each scale. Read on to learn the formulas, find example calculations, and explore the distinctions between GPA systems.

How to Convert CGPA to Percentage on a 10-Point Scale

The 10-point CGPA scale is frequently used in India and other regions, and it can be converted to a percentage with a simple formula.

• Formula: Percentage = CGPA × 9.5
• Example: If your CGPA is 8, the percentage conversion is calculated as:
  • Percentage = 8 × 9.5 = 76%

How to Convert CGPA to Percentage on a 5-Point Scale

On the 5-point CGPA scale, commonly found in certain international universities:

• Formula: Percentage = (CGPA ÷ 5) × 100
• Example: For a CGPA of 4.5, the percentage conversion would be:
  • Percentage = (4.5 ÷ 5) × 100 = 90%

How to Convert CGPA to Percentage on a 4-Point Scale

Widely used in U.S. institutions, the 4-point CGPA system has its conversion method:

• Formula: Percentage = (CGPA ÷ 4) × 100
• Example: For a CGPA of 3.5, the calculation is:
  • Percentage = (3.5 ÷ 4) × 100 = 87.5%

Understanding CGPA

CGPA, or Cumulative Grade Point Average, is an academic performance metric representing the average grade points a student achieves across all subjects over an academic period. Educational institutions around the world use CGPA to measure a student’s overall achievement. Calculating CGPA involves dividing the total grade points by the number of subjects taken. This value can then be converted to a percentage for broader application in various educational systems.

How to Calculate CGPA?

To calculate CGPA:

1. Sum the grade points of each subject.
2. Divide this total by the number of subjects.

Example: If your subjects add up to a total grade point of 40 across 5 subjects, your CGPA is:

• CGPA = 40 ÷ 5 = 8

Once you have the CGPA, converting it into a percentage can be done by multiplying by 9.5 (for the 10-point scale) or using the relevant conversion formula for other scales.

Here is a quick reference table to help convert common CGPA scores into percentages:

CGPA	Equivalent Percentage (%)
10	95%
9.5	90.25%
9	85.5%
8.5	80.75%
8	76%
7.5	71.25%
7	66.5%
6.5	61.75%

Understanding GPA Grading Systems Globally

Different grading scales are used worldwide, depending on the institution’s country and educational system. Here are two of the most common systems beyond the 10-point scale:

4-Point GPA System

This system is most prevalent in North American universities, including those in the United States.

4-Point GPA Scale

Percentage Range	Grade	GPA (4-Point Scale)
90-100%	A	4.0
80-89%	B	3.0
70-79%	C	2.0
60-69%	D	1.0
Below 60%	F	0.0

5-Point GPA System

While less common, certain universities use the 5-point GPA scale to offer finer differentiation between student grades.

5-Point GPA Scale

Percentage Range	Grade	GPA (5-Point Scale)
95-100%	A+	5.0
90-94%	A	4.5
80-89%	B	4.0
70-79%	C	3.0
60-69%	D	2.0
Below 60%	F	0.0

Difference Between CGPA and SGPA

• CGPA (Cumulative Grade Point Average): Reflects a student’s entire academic performance over a year.
• SGPA (Semester Grade Point Average): Measures performance within a particular semester, useful for semester-based assessments.
