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.

| 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 |

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
