CGPA to Percentage Converter

CGPA (Cumulative Grade Point Average) to percentage conversion is used primarily in Indian universities and some other Asian educational systems where internal grading uses a GPA scale but certificates, job applications, and further studies require a percentage equivalent.

Standard Indian university conversion formula: Percentage = CGPA × 9.5

This formula was standardized by the Central Board of Secondary Education (CBSE) and is widely adopted. A CGPA of 10 (maximum) equates to 95%, not 100%, because 9.5 represents the midpoint of the 90–100% band for an “A+” grade.

Reverse, percentage to CGPA: CGPA = Percentage ÷ 9.5

10-point GPA scale, the typical Indian university mapping:

One wrinkle at the bottom of that table: multiply a grade point of 4 by 9.5 and you get 38%, which falls under the 40% pass mark the same table sets for a P. The bands were written to describe the marks that earn each grade point, not to be run back through the ×9.5 formula. The conversion is a blunt instrument built for the middle of the range, and it was never meant to reconstruct a borderline pass. If you are near the pass line, use the actual marks.

CGPA calculation formula: CGPA = Σ (Grade Points × Credit Hours) ÷ Σ Credit Hours

This is a weighted average, so courses carrying more credit hours pull the CGPA further than light ones do.

International GPA equivalents (approximate):

• 10-point scale 9.5 to 10.0 is roughly a 4.0 US GPA (A)
• 8.5 to 9.4 is roughly 3.7 to 3.9 (A−)
• 7.5 to 8.4 is roughly 3.3 to 3.6 (B+)
• 6.5 to 7.4 is roughly 3.0 to 3.2 (B)

A CGPA of 9.5 works out at 90% under the ×9.5 formula, and that is the figure the International Grade Converter treats as a US 4.0, so the two pages line up.

Worked example: Student’s subject-wise grades (10-point scale):

• CGPA = (9×4 + 8×4 + 7×3 + 8×2 + 9×5) ÷ (4+4+3+2+5) = (36+32+21+16+45) ÷ 18 = 150 ÷ 18 = 8.33 CGPA
• Percentage = 8.33 × 9.5 = 79.1%

This corresponds to a “Very Good / A” grade on most Indian university scales.
