Convert between GPA, CGPA, and Percentage
This calculator performs three types of academic grade conversion:
Convert any GPA or CGPA to a percentage using the correct formula for your scale.
Convert a percentage to GPA on any scale (4.0, 5.0, 7.0, 10.0, etc.).
Convert between scales (e.g., 5.0 weighted to 4.0 unweighted, or 10.0 to 4.0).
Percentage = (GPA / Max Scale) x 100
Works for 4.0, 5.0, 7.0, 12.0, and 20.0 scales. Example: 3.5 on a 4.0 scale = (3.5 / 4.0) x 100 = 87.5%
Percentage = CGPA x 9.5
Standard CBSE formula. Example: 8.0 CGPA = 8.0 x 9.5 = 76%. Note: Some Indian universities use different multipliers (e.g., UGC uses (CGPA - 0.75) x 10).
No conversion needed - percentage is the native scale
UK and many European systems use percentage directly. To convert to US 4.0 GPA: GPA = (Percentage / 100) x 4.0.
| Country | Scale | Conversion | Notes |
|---|---|---|---|
| United States | 4.0 | (GPA / 4) x 100 | Most common; weighted 5.0 also used |
| Canada | 4.0 / 4.3 | (GPA / 4.3) x 100 | Varies by province; UBC uses 4.3 |
| India (CBSE) | 10.0 (CGPA) | CGPA x 9.5 | Standard CBSE formula; UGC varies |
| Australia | 7.0 | (GPA / 7) x 100 | HD=7, D=6, C=5, P=4, F=0 |
| United Kingdom | % direct | No conversion | Classifications: First, 2:1, 2:2, Third |
| Germany | 1.0-5.0 | Bavarian formula | 1.0=best, 5.0=fail |
| France | 0-20 | (Grade / 20) x 100 | 10+/20 = passing |
| Europe (ECTS) | A-F / 20 | (Grade / 20) x 100 | A=best, F=fail |
| Netherlands | 1-10 | (Grade / 10) x 100 | 10=perfect, 6=passing |
| Brazil | 0-10 | (Grade / 10) x 100 | 5+/10 = passing |

GPA = 3.5: (3.5 / 4.0) x 100 = 87.5% — Letter Grade: B+
CGPA = 8.5: 8.5 x 9.5 = 80.75% — US 4.0: 3.23
GPA = 5.5: (5.5 / 7.0) x 100 = 78.6% — US 4.0: 3.14
GPA = 4.2 on 5.0: (4.2 / 5.0) x 4.0 = 3.36 on 4.0
This GPA to Percentage Calculator provides estimates for educational and informational purposes. Conversion formulas may vary depending on university or institution policies.
For official transcripts, credential evaluations, or formal applications, use your institution official conversion or a recognized credential evaluation service such as WES.
The conversion depends on your grading scale. For the US 4.0 scale: Percentage = (GPA / 4.0) x 100. For the CBSE 10-point scale (India): Percentage = CGPA x 9.5. For a 5.0 scale: Percentage = (GPA / 5.0) x 100. The calculator above handles all these automatically.
