GPA / CGPA Calculator (India & US)
A GPA / CGPA Calculator is an essential academic tool that helps students measure their educational performance quickly and accurately. Whether you are studying in India using percentage-based grading or in the United States using the 4.0 GPA system, understanding your academic standing is important for college admissions, scholarships, internships, higher education, and career opportunities. This calculator simplifies the process by automatically calculating your Grade Point Average (GPA), Cumulative Grade Point Average (CGPA), average marks, and overall academic performance.
