CGPA to GPA Calculator
Convert a 10-point CGPA to a 4.0-scale GPA, or back, in one step. Estimate only — evaluation services and universities publish their own official conversions.

How CGPA to GPA conversion works
CGPA systems (such as the Indian 10-point scale) compress grades differently from the US 4.0 scale, so no single official conversion exists. The most common approach is proportional: divide by your scale maximum and multiply by 4.
Universities and evaluation services such as WES may apply their own tables instead. Treat this result as a planning estimate and use the exact method published by the institution you are applying to.
How to use the calculator
- 1
Pick your scale
Choose the maximum of your home scale: 10, 7, 5, or 4 points.
- 2
Enter your CGPA or GPA
The converter works in both directions with the same proportional rule.
- 3
Check the target institution
If the university publishes its own conversion or requires an evaluation report, that method wins.
GPA formula
US GPA = CGPA / scale maximum x 4
Proportional conversion assumes the scales are linearly comparable. Some universities instead convert through percentages or official evaluation tables.
CGPA conversion example
A student with an 8.5 CGPA on a 10-point scale converts proportionally:
| Step | Value |
|---|---|
| CGPA | 8.5 / 10 |
| As a fraction | 0.85 |
| On the 4.0 scale | 0.85 x 4 |
The estimated US GPA is 3.4.
Before you report a converted GPA
- Many US graduate schools ask for the original CGPA and scale rather than a self-converted value.
- Credential evaluation services may produce a different number from the proportional estimate.
- A converted GPA never replaces an official transcript or evaluation report.
Frequently asked questions
Is CGPA divided by 10 and multiplied by 4 official?
It is the most common proportional method, but it is not universal. Some universities convert via percentages or use evaluation services with their own tables.
Should I write the converted GPA on my application?
Only if the application explicitly asks for a 4.0-scale value and does not prescribe a method. Otherwise report your original CGPA and scale.
What about percentage-based Indian universities?
Some institutions publish their own percentage equivalence (for example CGPA x 9.5). Convert to a percentage first if that is the published rule, then apply the target institution method.
Can I convert a US GPA back to CGPA?
Yes — switch the direction in the converter. The same proportional rule applies in reverse.
