How Percentage to CGPA Conversion Works
The conversion from percentage to CGPA depends on the grading scale selected. Each scale uses a different ratio between percentage and grade point values.
10.0 Scale Conversion (Standard in India): CGPA = Percentage ÷ 9.5
Example: 85% ÷ 9.5 = 8.95 CGPA
This is the most widely used conversion formula across Indian universities including those affiliated with CBSE, Anna University, and VTU.
4.0 Scale Conversion (Standard in USA): CGPA is mapped from percentage using the following standard ranges:
| Percentage | 4.0 Scale CGPA |
|---|---|
| 90% to 100% | 3.7 to 4.0 |
| 80% to 89% | 3.3 to 3.6 |
| 70% to 79% | 3.0 to 3.2 |
| 60% to 69% | 2.7 to 2.9 |
| 50% to 59% | 2.3 to 2.6 |
| 40% to 49% | 2.0 to 2.2 |
| 30% to 39% | 1.0 to 1.9 |
| Below 30% | 0.0 to 0.9 |
5.0 Scale Conversion: CGPA is mapped proportionally between 0.0 and 5.0 based on percentage ranges used by institutions that adopt a five-point grading system.
