How Does CGPA to GPA Conversion Work?
CGPA and GPA can be expressed using different grading scales. This calculator uses a linear mapping between the selected scales. For example, when converting from a 10-point CGPA scale to a 4-point GPA scale, the CGPA is divided by 10 and multiplied by 4.
GPA = (CGPA / CGPA Scale) × GPA Scale
The reverse calculation uses the same principle:
CGPA = (GPA / GPA Scale) × CGPA Scale
Important:
This calculator provides an estimated linear conversion.
Universities and educational institutions may use their own
formulas, grading bands, credit-weighted systems, or conversion
rules. Always check your institution's official grading policy
when an exact conversion is required.
