Grade & GPA
GPA Table Converter
One grade, looked up across every scale at once — letter, percentage, 4.0 GPA and 10-point CGPA.

Conversion rules differ between institutions. Check the formula shown against your own university's published rule before using the result on an application or transcript.
About the GPA Table Converter
Four grading systems, one grade. Enter a value in whichever system you have — a letter, a percentage, a 4.0 GPA or a 10-point CGPA — and this tool shows the equivalent in all the others at once. No repeated lookups, no juggling three tabs.
It is built for the moments when systems collide. Reading a transcript from another country, filling in an application that wants a scale you do not use, or checking whether your CGPA clears a GPA cutoff. The full conversion table appears with your grade highlighted, so you can see where you sit relative to the bands above and below.
Conversions between grading systems are approximations by nature, and the page says so where it matters. Institutions publish their own tables and are entitled to differ. Use this for orientation and planning; use your registrar for anything binding.
How to use the GPA Table Converter
- Choose what you are converting from.
- Enter the value, or pick a letter grade.
- Select Convert.
- Every equivalent is shown at once.
- Your grade’s row is marked in the full table below.
The master GPA conversion table
Every row is one grade band, expressed four ways. Percentages use the standard US plus/minus system, and the CGPA column applies the common 10-point convention.
| Letter | Percentage | GPA (4.0) | CGPA (10-point) | Classification |
|---|---|---|---|---|
| A+ | 97–100% | 4.0 | 10.0 | Distinction |
| A | 93–96% | 4.0 | 9.8–10.0 | Distinction |
| A− | 90–92% | 3.7 | 9.5–9.7 | Distinction |
| B+ | 87–89% | 3.3 | 9.2–9.4 | Distinction |
| B | 83–86% | 3.0 | 8.7–9.1 | Distinction |
| B− | 80–82% | 2.7 | 8.4–8.6 | Distinction |
| C+ | 77–79% | 2.3 | 8.1–8.3 | Distinction |
| C | 73–76% | 2.0 | 7.7–8.0 | Second class |
| C− | 70–72% | 1.7 | 7.4–7.6 | Second class |
| D+ | 67–69% | 1.3 | 7.1–7.3 | First class |
| D | 63–66% | 1.0 | 6.6–7.0 | First class |
| D− | 60–62% | 0.7 | 6.3–6.5 | First class |
| F | Below 60% | 0.0 | Below 6.3 | Second class or below |
The last four rows look strange for a reason, and it is worth understanding. A 65% is a D in the US system but a First class result in most Indian universities. The same mark carries genuinely different meaning in different systems. Never move a grade between systems without stating which system it came from.
The conversions being applied
Percentage → GPA : map to letter band, take that letter's points
Percentage → CGPA : percentage ÷ 9.5
CGPA → percentage : CGPA × 9.5
GPA → percentage : GPA × 25
Entering a letter uses the midpoint of its percentage band, since a letter covers a range rather than a single value.
Worked example
You hold a CGPA of 8.5 on a 10-point scale and an application asks for a 4.0 GPA.
Percentage: 8.5 × 9.5 = 80.75%.
That falls in the 80–82% band, which is a B−.
B− on the letter scale — 2.7 on the 4.0 scale
Dividing 80.75 by 25 would have suggested 3.23. The banded result is the one a registrar would recognise, and it is considerably lower. Plan around it.
Converting a weighted GPA to unweighted
There is no formula for this, and any tool that offers one is guessing. The weighting bonus depends on how many honours or AP courses you took and what bonus your school applied — information a single number does not carry.
To do it properly, go back to your transcript and recalculate from the base letter grades with every bonus removed. Our 4.0 scale calculator does exactly that. As a rough sanity check, weighted GPAs typically sit 0.2 to 0.6 above their unweighted counterparts, but that spread is too wide to rely on.
Reading the table without being misled
- A letter is a range, not a point. Converting a letter to a percentage means picking a representative value, and this tool uses the band midpoint.
- The ×9.5 rule is a convention. It comes from CBSE practice in India and is widely used, but it is not universal. Some universities publish a different multiplier.
- Classification bands are not US letter grades. They belong to a separate system with a different pass mark, and they are shown alongside for reference, not as an equivalence.
- Round trips lose accuracy. Convert percentage to CGPA and back and you may not land on your starting number. Convert once, from your original grade.

What letter grade is my GPA?
A GPA is an average, so it often falls between two letters. Use this quick lookup on the standard 4.0 scale:
| GPA | Letter grade | Approx. percentage |
|---|---|---|
| 4.0 | A | 93–100% |
| 3.7 | A− | 90–92% |
| 3.5 | Between B+ and A− | about 89–90% |
| 3.3 | B+ | 87–89% |
| 3.2 | B (high) | about 86% |
| 3.0 | B | 83–86% |
| 2.8 | B− (high) | about 81% |
| 2.7 | B− | 80–82% |
| 2.5 | Between C+ and B− | about 78–80% |
| 2.0 | C | 73–76% |
So a 3.3 GPA is a B+ average, a 3.0 is a B, and a 2.5 sits between a C+ and a B−.
How to convert a percentage to GPA
- Find the letter grade for your percentage (for example, 88% is a B+).
- Look up that letter's grade points (B+ = 3.3).
- For several courses, average the points, weighted by credits.
Dividing by 25 (88 ÷ 25 = 3.52) is a common shortcut, but registrars use bands, not division. The percentage to GPA converter shows both methods side by side.

Frequently asked questions
On the standard US plus/minus scale, an A covers 93–100% and an A− covers 90–92%. Schools that award an A+ set it at 97% and above. Some institutions drop plus/minus grading entirely, in which case an A usually starts at 90%. Your student handbook is the authority — the bands genuinely differ, and the difference can be three percentage points.
Each letter has a fixed grade point value: A and A+ are 4.0, A− is 3.7, B+ is 3.3, B is 3.0, B− is 2.7, and so on down in roughly 0.3 steps to D− at 0.7 and F at 0.0. There is no arithmetic involved — it is a lookup. Enter the letter above and the tool returns the points along with the percentage and CGPA equivalents.
Roughly 8.9 on a 10-point scale, using the standard division by 9.5. Reversing it, a CGPA of 8.9 gives 84.55%. Bear in mind this multiplier is a CBSE-derived convention rather than a universal rule, so your university may publish a different one. Check your institution's own conversion notice before quoting the figure on an application.
No, and the differences are real. Some schools award 4.3 for an A+, some ignore plus and minus altogether, and the percentage boundaries move by a few points between institutions. Indian universities use classification bands with a 40% pass mark, so a 65% is a First class there and a D in the US. Always convert from your own institution's published table when the result matters.
A 3.3 GPA is a B+ on the standard 4.0 scale, roughly 87% to 89%. A 3.0 is a B and a 3.7 is an A−.
