CGPA stands for Cumulative Grade Point Average, which is a way to measure a student's overall academic performance in a subject. It's calculated by taking the average of the grades earned in each semester and dividing it by the total number of credits. The highest CGPA a student can achieve is between 9.5 and 10 grade points.To calculate CGPA, you add up the grade points for all major subjects and divide by the number of subjects.To convert CGPA to percentage, you multiply your CGPA by 9.5. For example, if your CGPA is 9.4, your percentage would be 9.4 * 9.5 = 89.3%. This formula is provided by organizations like CBSE for students in grades IX and X.

Cumulative Grade Point Average.

CGPA is converted into percentage using the equation: Percentage (%) = 7.1 * CGPA + 11.For example, if your CGPA is 6.2, you can convert it to a percentage by multiplying it by 7.1 and adding 11:Percentage (%) = 7.1 * 6.2 + 11 Percentage (%) = 43.42 + 11 Percentage (%) = 54.42So, if your cumulative grade point average (CGPA) is 6.2, it would be converted to approximately 54.42 percent.

The Semester Grade Point Average (SGPA) is a measure of a student's performance in a particular semester. It's calculated by taking the weighted average of the grade points earned in all the courses the student took during that semester. In simple terms, it shows how well a student did in their classes for that specific period of time.

Calculating SGPA is quite simple. Here's how you do it:List down the credit points earned in each subject you took during the semester. Multiply the credit point value of each subject by the grade you received in that subject. If the grades fall within a range, you can use the median value. Add up all these scores to get a total. Divide the total score obtained by the sum of all your credit points. The number you get after dividing represents your Semester Grade Point Average (SGPA).

To calculate CGPA, which represents the overall academic performance for an academic year, you first need to find the average score of all subjects in each semester, known as SGPA. Then, to compute CGPA, add up all the SGPAs from all semesters and divide the total by the number of semesters.Here are some formulas and methods commonly used to convert between SGPA, CGPA, and percentage:SGPA to Percentage (General): [(SGPA * 10) – 7.5 = Percentage]Where SGPA is the Semester Grade Point Average. SGPA to Percentage (Specific): [(SGPA * 10) – 7.5 = Percentage]Where Ci is the credit assigned for a course and GPi is the grade point for that course. SGPA to CGPA (SPPU Method): SGPA = (C1G1 + C2G2 + C3G4 + C4G4 + C5G5)/ (C1 + C2 +C3 + C4 + C5)Where C1, C2, C3, C4, C5 are course credits and G1, G2, G3, G4, G5 are grade points of the respective courses. SGPA to CGPA (VTU Method): SGPA = Σ(Ci×Gi)/ΣCiWhere Ci is the credit assigned for a course and Gi is the grade point for that course. These formulas are used in different educational institutions or systems to convert between SGPA, CGPA, and percentage based on their specific grading and credit systems.
