There has been considerable confusion in Delhi University's grading system for a long time. The university proposed multiple adjustments before a proper method was finally implemented and made public. The SGPA calculator is used in the educational field to translate SGPA to percentage. The calculations are based on the student's overall performance on the corresponding semester exam in general courses. 

To convert SGPA into a percentage, the following steps are being followed by the students:

• The SGPA for each semester should be determined first.

• Adding the semester-by-semester averages once you get them.

• Subtracting the number of semesters you have taught from the total of the SGPAs.

• Finally, calculate your SGPA by multiplying it by 10, then take 7.5 out of the result. 

The CBCS System used at DU is Relative Grading rather than Absolute Grading.
