How to Convert Percentage to GPA (4.0 Scale)
If you studied under a percentage system and are applying to a US university, you will need a rough 4.0-scale equivalent for your applications. Here is the standard conversion table, how to use it, and the caveats you need to know before you put a number on your resume.
The standard percentage-to-GPA table
Most US high schools and colleges that use plus/minus grading follow this table. It is the same table used by our free GPA converter.
| Percentage | Letter grade | Grade points (4.0) |
|---|---|---|
| 97–100 | A+ | 4.0 |
| 93–96 | A | 4.0 |
| 90–92 | A- | 3.7 |
| 87–89 | B+ | 3.3 |
| 83–86 | B | 3.0 |
| 80–82 | B- | 2.7 |
| 77–79 | C+ | 2.3 |
| 73–76 | C | 2.0 |
| 70–72 | C- | 1.7 |
| 67–69 | D+ | 1.3 |
| 63–66 | D | 1.0 |
| 60–62 | D- | 0.7 |
| Below 60 | F | 0.0 |
How to convert, step by step
- Find your percentage for the course or semester (e.g., 85%).
- Look up the letter grade in the table above (85% → B).
- Read off the grade points (B → 3.0). That is your GPA for that course on the 4.0 scale.
For a semester or cumulative GPA, average the grade points, weighted by credit hours:
| Course | Credits | Percentage | Grade points | Weighted points |
|---|---|---|---|---|
| Calculus I | 4 | 91% (A-) | 3.7 | 14.8 |
| English Composition | 3 | 84% (B) | 3.0 | 9.0 |
| Intro Psychology | 3 | 78% (C+) | 2.3 | 6.9 |
| Total | 10 | 30.7 |
GPA = 30.7 ÷ 10 = 3.07. Use ourGPA converter to do this instantly for any set of grades.
Worked examples
- 85% → B → 3.0 GPA
- 92% → A- → 3.7 GPA (93%+ would be a 4.0)
- 71% → C- → 1.7 GPA
- 65% → D → 1.0 GPA
No plus/minus? Use the 10-point table instead
Many schools (and some entire states' systems) grade with simple letter bands and no plus or minus. Their table is even simpler:
| Percentage | Letter grade | Grade points |
|---|---|---|
| 90–100 | A | 4.0 |
| 80–89 | B | 3.0 |
| 70–79 | C | 2.0 |
| 60–69 | D | 1.0 |
| Below 60 | F | 0.0 |
Under this system an 88% is a flat B (3.0), while under plus/minus it would be a B+ (3.3). Always use the table your own school publishes.
Converting from other scales (10-point CGPA, 7-point, etc.)
If you studied under a 10-point CGPA, an Australian 7-point scale, a Canadian 4.3 scale, or a Chinese 5.0 scale, there are commonly used reference formulas — but no official standard. OurInternational GPA Converter handles all of these in one click, with the formula shown for each result.
The important caveat: there is no official standard
Conversion tables differ between schools, states, and countries. US admissions offices know this: many recalculate your GPA from your official transcript using their own method, and some require a credential evaluation from an agency such as WES orECE. Use this guide (and any converter) to get a reference estimate — and if a university asks for an official evaluation, follow their process rather than submitting a self-converted number.
Frequently asked questions
What percentage is a 4.0 GPA?+
On the standard US unweighted scale, a 4.0 GPA corresponds to an A, which most schools define as 93–100% (with plus/minus grading) or 90–100% (with simple 10-point grading). Exactly which ranges your school uses matters, so check its grading policy.
How do I convert 85% to a GPA?+
Using the common plus/minus table, 85% falls in the B range: 83–86% is a B, worth 3.0 grade points. So 85% ≈ 3.0 GPA. With simple 10-point grading (80–89% = B), it is also 3.0.
What is a 90% average in GPA?+
90% is the boundary between A- and A. With plus/minus grading, 90–92% is an A- (3.7 GPA). With simple 10-point grading, 90%+ is an A (4.0 GPA). The answer depends on your school's table.
Is a 75% a good grade?+
75% is a C on most US scales (73–76% = C, 2.0 GPA; or 70–79% = C with simple grading). A C is a passing grade but below the 3.0 (B average) that competitive programs often expect.
Why does my university convert my percentage differently?+
There is no official universal conversion standard. Universities, admission offices, and credential evaluation services such as WES and ECE each use their own method, and many US universities recalculate your GPA from your original transcript. Treat any percentage-to-GPA conversion as a reference estimate, not an official number.
How do I convert a percentage to GPA if my school has no plus/minus grades?+
Use the simple 10-point table instead: 90–100% = A (4.0), 80–89% = B (3.0), 70–79% = C (2.0), 60–69% = D (1.0), below 60% = F (0.0). This is common in many US high schools and colleges.
How do I convert a 10-point CGPA to a 4.0 GPA?+
The most common reference formula (used by many Indian and Nepali universities as a rough equivalent) is GPA = CGPA × 0.4. For example, an 8.5 CGPA becomes 3.4 on the 4.0 scale. There is no official universal standard, so always confirm with the university or a credential evaluation agency (such as WES) you are applying to.
What is a 3.5 GPA in percentage?+
A 3.5 GPA sits between a B+ (3.3, typically 87–89%) and an A- (3.7, typically 90–92%), so it roughly corresponds to about 88–90% on the percentage scale, depending on the exact table your school uses.
What percentage is a 3.0 GPA?+
A 3.0 GPA is a B, which corresponds to roughly 83–86% under the standard plus/minus table (or 80–89% under simple 10-point grading).
Does a 4.0 GPA include A+?+
On the standard unweighted 4.0 scale, an A+ (97–100%) converts to 4.0 — the same as an A. Only on extended scales like the Canadian 4.3 scale does A+ carry extra weight (4.3), which is typically capped back to 4.0 when converting to the US scale.
