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, and are the same 4.0 GPA scale nearly every US school reports on. That GPA grade scale is what the converter maps a percentage onto. 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
What is the letter GPA scale?
The letter GPA scale is the standard mapping of letter grades to grade points on a 4.0 scale: A is 4.00, A- is 3.67, B+ is 3.33, B is 3.00, and so on down to D at 1.00 and F at 0.00. It is the scale nearly every US school reports on, though some publish one-decimal values (3.7, 3.3) instead.
What does a GPA scale of 4.0 actually mean?
It means 4.00 is the value of the top grade, so a perfect record produces a 4.0. Each letter grade below it carries a fixed fraction of that. A few schools award an A+ above 4.00 — the University of Iowa and Columbia use 4.33 — so a 4.0 scale is not always a hard ceiling.
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.
