What Is the GPA to CGPA Calculator?
This tool converts a Grade Point Average (GPA) measured on the common 4.0 scale into a Cumulative Grade Point Average (CGPA) on the 10-point scale used by many universities, particularly in India and parts of Asia. It is useful for students applying across systems, transferring credits, or filling out applications that require a 10-point CGPA when their transcript reports a 4.0 GPA.
How to Use It
Enter your GPA on the 4.0 scale (for example, 3.5) and the calculator instantly returns the equivalent CGPA out of 10, along with an approximate percentage. The conversion assumes a simple linear proportional mapping between the two scales.
The Formula Explained
The core conversion scales the 4.0 maximum up to a 10.0 maximum:
$$\text{CGPA} = \frac{\text{GPA}}{4} \times 10$$
An approximate percentage is derived by \(\text{Percentage} = \text{GPA} \times 25\), since a perfect 4.0 corresponds to 100%. Note these are linear approximations — actual institutional conversion rules vary, so always confirm with your school or the receiving institution.
Worked Example
Suppose your GPA is 3.5 on the 4.0 scale. Then $$\text{CGPA} = \frac{3.5}{4} \times 10 = 0.875 \times 10 = 8.75$$ out of 10. The approximate percentage is \(3.5 \times 25 = 87.5\%\).
FAQ
Is this conversion official? No. It is a standard linear approximation. Many universities publish their own conversion tables, which may differ slightly.
What CGPA equals a perfect GPA? A 4.0 GPA maps to a 10.0 CGPA and 100%.
Can I use this for the reverse conversion? To go from a 10-point CGPA back to a 4.0 GPA, divide the CGPA by 10 and multiply by 4.
