CGPA to percentage converter
Conversion formulas vary by institution and country — confirm your university’s official method before using a converted figure on applications.
How GPA is calculated
Grade Point Average (GPA) on the standard 4.0 scale converts each letter grade into grade points, weights them by the credit hours of each course, and averages the result. The formula is GPA = total (grade points × credits) ÷ total credits. An A is worth 4.0, a B 3.0, a C 2.0 and a D 1.0, with pluses and minuses adjusting the value (an A− is 3.7, a B+ is 3.3, and so on). Courses worth more credits influence your GPA more, which is why a strong grade in a high-credit course matters more than the same grade in a small one.
4.0 grade-point scale
| Letter | Points | Letter | Points |
|---|---|---|---|
| A / A+ | 4.0 | C+ | 2.3 |
| A− | 3.7 | C | 2.0 |
| B+ | 3.3 | C− | 1.7 |
| B | 3.0 | D | 1.0 |
| B− | 2.7 | F | 0.0 |
CGPA and converting to a percentage
CGPA (Cumulative Grade Point Average) is your GPA across all semesters or years. Converting a CGPA to a percentage is common for job and university applications, but there is no single universal formula. A widely used method — popularised by India’s CBSE board — multiplies a 10-point CGPA by 9.5. Other institutions multiply a 10-point CGPA by 10, or publish their own conversion table. Because methods differ, always confirm the official formula your institution or the receiving organisation accepts before relying on a converted figure.
