Why GPA Scales Don't Convert Perfectly
A percentage is continuous — 91% and 92% are meaningfully different. A 4.0 GPA is banded — both of those percentages round to the same A- (3.67). Converting between the two always loses some precision in one direction, which is why this tool (and every GPA scale converter) gives a close standard estimate rather than an exact, universal answer.
The bands used here — 93–100% is a 4.0, 90–92% is 3.67, and so on — match the table on the main GPA calculator. They're the most common US convention, but plenty of schools set their own cutoffs a point or two either side.
Percentage, GPA and CGPA Side by Side
| Percentage | GPA (4.0) | CGPA (10-point, approx.) |
|---|---|---|
| 93–100% | 4.00 | 9.5–10.0 |
| 90–92% | 3.67 | 9.5–9.7 |
| 87–89% | 3.33 | 9.2–9.4 |
| 83–86% | 3.00 | 8.7–9.1 |
| 80–82% | 2.67 | 8.4–8.6 |
| 77–79% | 2.33 | 8.1–8.3 |
| 73–76% | 2.00 | 7.7–8.0 |
| 70–72% | 1.67 | 7.4–7.6 |
| 67–69% | 1.33 | 7.1–7.3 |
| 60–66% | 1.00 | 6.3–6.9 |
| Below 60% | 0.00 | Below 6.3 |
CGPA column uses percentage ÷ 9.5 — the widely-used approximation, not an official standard. If your university publishes its own CGPA-to-percentage formula, use that one for anything official.
Frequently Asked Questions
How do I convert a percentage to a 4.0 GPA?
Match your percentage to the letter-grade band it falls in (93-100% is a 4.0, 90-92% is 3.67, and so on down to below 60% at 0.0), then use that band's grade point. There is no single official formula because grading bands vary by school, so treat the result as a close standard-scale estimate.
How do I convert a 10-point CGPA to a percentage?
The most common approximation, used informally by many Indian universities, is percentage = CGPA × 9.5. Some universities publish their own official formula instead (for example CGPA minus 0.75, then ×10) — check your specific university's conversion policy for anything that needs to be exact, like a visa or job application.
Is there one universal formula for converting GPA scales?
No. Every school and country sets its own grading bands, so any converter — including this one — gives a close standard estimate, not an official transcript conversion. When a specific number needs to be exact, use the conversion your issuing institution publishes.
