How to use it
- Pick what you want to convert: CGPA to percentage, percentage to CGPA, or a 4.0 GPA to a rough percentage.
- Enter the value. The multiplier starts at 9.5 (CBSE); change it if your university gives another.
- Read the result below.
The formulas
- CBSE (10-point CGPA): percentage = CGPA × 9.5. This is the board’s own rule.
- Other universities: percentage = CGPA × the multiplier the university states. Enter it in the multiplier field. The calculator does not know any institution’s rule, so it never picks a multiplier for you.
- Back to CGPA: CGPA = percentage ÷ multiplier.
- 4.0 GPA, rough: percentage ≈ GPA ÷ 4 × 100. This is only a stretch of one scale onto another. A US 3.0 is a B, which usually means somewhere around 80 to 89 percent, not 75.
Worked example
A CBSE student has a CGPA of 8.4. Percentage = 8.4 × 9.5 = 79.8 %. In reverse, 85.5 % ÷ 9.5 = 9.0 CGPA.
Tips
- Use the same formula your target college or employer names. If they name none, say which one you used.
- A result above 100 percent means the multiplier does not fit your scale; check it.
- Do not mix scales: a CGPA out of 10 is not a GPA out of 4.0.
