About SGPA to CGPA Calculator

SGPA is the grade point average of one semester; CGPA is the average over all semesters so far. When every semester carries the same credits, CGPA is simply the average of the SGPAs.

When credits differ, each SGPA is weighted by its credits: CGPA = Σ(SGPA × credits) ÷ Σ credits. For SGPAs of 8.0 (20 credits) and 9.0 (24 credits), the CGPA is (160 + 216) ÷ 44 = 8.55.

Is CGPA the average of SGPA?

Only when all semesters have equal credits. Otherwise semesters with more credits count for more.

How do I convert the CGPA to a percentage?

Use the first tab with the formula your university prints, such as CGPA × 10 or (CGPA − 0.75) × 10.
