Convert a 10-point CGPA to a 4.0-scale GPA with the proportional estimate (CGPA ÷ 10 × 4), plus the full chart both ways — and an honest note on what US universities actually use.
| Input | Result |
|---|---|
| 8.0 CGPA | 3.20 GPA (proportional estimate) |
| 9.0 CGPA | 3.60 GPA (proportional estimate) |
| 7.5 CGPA | 3.00 GPA (proportional estimate) |
| 8.2 CGPA | 3.28 GPA (proportional estimate) |
Before the number, the honest context: the 10-point CGPA and the 4.0 GPA are built differently, and no official formula converts one into the other. CGPA is a credit-weighted average of grade points on a 10-point scale where pass marks and grade bands are set by each Indian university. The US GPA averages grade points on a 4.0 scale where each letter grade has a fixed value. A single multiplier cannot capture that difference, which is why credential-evaluation services exist.
The proportional estimate shown above (CGPA ÷ 10 × 4) answers the question most people actually have — roughly where do I stand? It is fine for shortlisting universities and satisfying your own curiosity. It is not fine for application forms: US graduate schools either evaluate your transcript course-by-course themselves or ask for a credential evaluation (WES and similar services), and the figure they compute routinely differs from the proportional one.
| CGPA (10-point) | GPA (4.0, proportional) | CGPA (10-point) | GPA (4.0, proportional) |
|---|---|---|---|
| 10.0 | 4.00 | 7.5 | 3.00 |
| 9.5 | 3.80 | 7.0 | 2.80 |
| 9.0 | 3.60 | 6.5 | 2.60 |
| 8.5 | 3.40 | 6.0 | 2.40 |
| 8.0 | 3.20 | 5.5 | 2.20 |
| 7.9 | 3.16 | 5.0 | 2.00 |
Reversing the same proportion (GPA ÷ 4 × 10) gives the notional CGPA equivalent of a US GPA — useful when an Indian form asks for a CGPA-scale equivalent and accepts an estimate:
| US GPA (4.0) | Notional CGPA (10-point) |
|---|---|
| 4.0 | 10.0 |
| 3.5 | 8.75 |
| 3.0 | 7.5 |
| 2.5 | 6.25 |
| 2.0 | 5.0 |
Admission offices that see Indian transcripts every cycle do not multiply by 0.4. The common paths are: evaluate the transcript in-house course-by-course (recalculating each grade onto their own scale), or require a credential-evaluation report from a service such as WES, which converts each course individually and then averages. Both methods respond to the shape of your transcript — strong marks in advanced courses count for more than the same average spread thin — which is exactly the information a single multiplier throws away.
The practical reading: treat the proportional figure as a floor for orientation, not a verdict. Indian grading is typically stricter at the top (a 9.0 CGPA is rarer than a 3.6 GPA), so evaluated conversions often land at or above the proportional estimate — but the evaluated number is the only one an admissions office will recognise. For percentage conversion inside the Indian system, use the CGPA to percentage calculator; for semester-level aggregation, the SGPA to CGPA calculator.
For a rough estimate, divide by 10 and multiply by 4: 8.0 CGPA ≈ 3.20 GPA. There is no official conversion — US universities evaluate Indian transcripts course-by-course or through a credential-evaluation service, and that figure can differ from the proportional estimate.
Proportionally, 8.0 ÷ 10 × 4 = 3.20 GPA. Treat it as orientation: Indian grading is often stricter at the top, so a formal evaluation may come out higher.
Proportionally yes (7.5 ÷ 10 × 4 = 3.0), but formally no — the two scales are built on different grade bands and no official mapping exists.
No. They either recalculate your transcript course-by-course in-house or ask for a credential-evaluation report (WES and similar). The proportional estimate is for your own shortlisting, not for application forms.
No — WES converts each course individually using its own grade tables and then averages, so its result routinely differs from any single-multiplier estimate. Use the proportional figure only to know roughly where you stand.
