How CGPA converts to percentage

CGPA stands for Cumulative Grade Point Average — the average of the grade points you earned across all subjects, usually on a 10-point scale. The Central Board of Secondary Education (CBSE) introduced a simple rule to turn that grade point into a percentage: multiply the CGPA by 9.5. So a CGPA of 8.0 becomes 8.0 × 9.5 = 76%, and a CGPA of 10 becomes the maximum 95%. The 9.5 factor comes from the average of the upper and lower marks of the top five grades in the CBSE grading band, which is why it became the board’s official multiplier.

Not every board or university uses 9.5, though. Some institutions multiply by 10, some subtract a fixed number first, and others publish their own conversion table. Always check your university handbook or marksheet for the exact formula before quoting a percentage on an application — using the wrong multiplier can over- or under-state your result. The custom card above lets you plug in whatever multiplier and scale your institution specifies.
