Marks to CGPA Calculator: Complete Guide to Converting Percentage to GPA
Understanding how to convert marks percentage to CGPA (Cumulative Grade Point Average) is essential for students applying to universities, scholarships, or jobs. Our free online calculator simplifies this conversion process, supporting multiple grading scales used worldwide.
What is CGPA and How is it Calculated?
CGPA stands for Cumulative Grade Point Average, which represents a student's overall academic performance across multiple semesters or courses. Unlike percentage systems that measure raw scores, CGPA provides a standardized metric that accounts for course credit hours and grade points.
The basic formula for converting percentage to CGPA is:
CGPA = (Percentage ÷ 100) × Maximum Grade Point
For example, on a 4.0 scale, 85% converts to: (85 ÷ 100) × 4.0 = 3.4 GPA
Different Grading Systems Explained
1. 4.0 Scale (Most Common)
Used primarily in the United States, Canada, and many international universities, the 4.0 scale is the global standard for GPA calculation. Most graduate schools and employers recognize this scale.
2. 10.0 Scale (Indian System)
Common in Indian universities, the 10-point scale often follows these classifications: 9-10 = Outstanding, 8-8.9 = Excellent, 7-7.9 = Very Good, 6-6.9 = Good, 5-5.9 = Above Average.

Many countries like the UK, Australia, and India use direct percentage marks. Conversion to GPA is often required when applying to international universities.
