How to Convert International Grades to a US GPA: A Country-by-Country Guide
If you studied outside the United States and you are applying to a US program, one of the first things you will try to do is convert international grades to a US GPA on the American 4.0 scale. It is a reasonable instinct: US admissions pages talk about GPA constantly, and you want to know whether your record reads like a 3.2 or a 3.8 before you build a list of schools. This guide gives you honest, country-by-country estimate tables — ECTS to GPA, UK honours classes, Indian percentages and 10-point CGPA, Chinese percentages, and a generic percentage to 4.0 GPA band — so you can size up your record quickly.
Here is the part most ranking-focused "GPA converter" pages bury: a number you calculate yourself is fine for planning, but it is not an official conversion. Real graduate applications, licensure, and immigration filings require a course-by-course evaluation from a credentials evaluator, and those evaluators do not use one universal formula. Keep that distinction in mind as you read — everything below is a planning estimate, not a verdict on your transcript.
The caveat every GPA converter skips
The GPA, the 4.0 scale, and letter grades A–F are US-specific conventions. Most of the world does not use them at all. So when you "convert" a First-class degree or an 8.4 CGPA into a 3.6, you are translating between two systems that were never designed to line up. There is no international standard for this and no official cutoff — the mapping depends on your country, and often on your specific university.
For an informal purpose — deciding which schools are realistic, or checking whether you clear a stated minimum — a self-calculated estimate is useful. For anything official, US institutions expect a course-by-course evaluation from a member of the National Association of Credential Evaluation Services (NACES). The best-known member is World Education Services (WES), but any NACES member follows the same principle: they read your transcript against country- and institution-specific reference tables and produce a verified US-equivalent GPA. Every table in this guide gives you an estimate for your college list — never an official evaluation.
How to convert international grades to a US GPA (the honest method)
The practical workflow is two steps, and only the first is country-specific:
- Map each course's grade to a US letter using the appropriate table for your system (below). This is the step where the estimate lives, and where the gotchas hide.
- Weight those letters by credits to get a single GPA number. A US GPA is credit-weighted: a four-credit course counts more than a one-credit seminar. This step is pure arithmetic, and it is exactly what a GPA calculator does for you.
Treat the tables below as illustrative, not authoritative. Grading conventions vary by school and even by instructor, and evaluators apply their own institution-specific scales. Confirm the meaning of your own marks against your transcript legend and your registrar. If you are hazy on how letters and percentages relate in the US system, our guide to how grading works covers the fundamentals.
The generic percentage-to-4.0 GPA band
If your transcript is already in percentages and your school uses a roughly US-style scale, this common band converts a percentage to a 4.0 GPA:
| Percentage | US letter | GPA points |
|---|---|---|
| 93–100 | 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 |
The gotcha: this band only works if a percentage in your country means roughly what it means on a US syllabus, where 90+ is routine for strong students and 60 is a near-failing D. In most of the world, it does not. A UK, Indian, or Australian 70% is an excellent result, not a C-minus. Applying this table to a system where high marks are rare will understate your record badly. Use it for US-style percentage transcripts and for the systems noted below — and use the country-specific tables everywhere else. For the US mechanics, see our guide on percentage to letter grade.
ECTS to GPA: Europe's relative A–F scale
Across the European Higher Education Area, courses carry ECTS credits (a workload measure — a full year is 60 credits) and are sometimes marked with ECTS grades A–E. A common estimate for ECTS to GPA looks like this:
| ECTS grade | Meaning | Estimated GPA |
|---|---|---|
| A | Excellent (top band) | 4.0 |
| B | Very good | 3.5 |
| C | Good | 3.0 |
| D | Satisfactory | 2.5 |
| E | Sufficient (lowest pass) | 2.0 |
| FX / F | Fail | 0.0 |
The gotcha: the ECTS grade is relative, not absolute. Historically an A meant roughly the top 10% of the passing cohort and a C the middle band, so the same raw exam mark could be an A in one class and a C in another. The European Commission's ECTS Users' Guide moved away from fixed percentile ranks toward grade-distribution tables that show how grades actually spread at a given institution — which is precisely why a single letter cannot be pinned to a fixed GPA. Also, do not confuse ECTS credits (workload) with ECTS grades (performance); and remember most European transcripts show a national mark (a German 1.0–5.0, a French 0–20, an Italian 18–30) rather than a letter at all. Those national scales each need their own table.
UK honours: First, 2:1, and 2:2 in GPA terms
UK degrees are classified rather than given a GPA. The class comes from your weighted marks, and the marks map very differently than newcomers expect:
| UK classification | Typical mark | Estimated GPA |
|---|---|---|
| First-class honours (1st) | 70%+ | 3.7–4.0 |
| Upper second (2:1) | 60–69% | 3.3–3.7 |
| Lower second (2:2) | 50–59% | 2.7–3.0 |
| Third-class (3rd) | 40–49% | 2.0–2.3 |
The gotcha: UK marks almost never exceed the low 80s, and a 70 is exceptional — a First. If you drop UK percentages into the generic band above, a First (70) becomes a C-minus, which is nonsense. A First typically evaluates to roughly an A, an upper second (2:1) to about an A-minus or B-plus, and a lower second (2:2) to roughly a B or B-minus. The exact result depends on the evaluator and your institution, but the headline is simple: never read a UK 70% as a US 70%.
India: percentage and the 10-point CGPA
Indian transcripts come in two main flavors. First, the classic percentage with class labels:
| Indian result | Percentage | Estimated GPA |
|---|---|---|
| First Class with Distinction | 75%+ | 3.7–4.0 |
| First Class | 60–74% | 3.3–3.7 |
| Second Class | 50–59% | 2.7–3.0 |
| Pass | 40–49% | 2.0 |
Second, the 10-point CGPA used by many universities:
| CGPA (10-point) | Estimated GPA |
|---|---|
| 9.0–10.0 | 3.9–4.0 |
| 8.0–8.9 | 3.5–3.8 |
| 7.0–7.9 | 3.1–3.4 |
| 6.0–6.9 | 2.7–3.0 |
| 5.0–5.9 | 2.3–2.6 |
The gotcha: Indian marking is strict, so First Class (60%) is a strong outcome, not a US-style D. A 75%+ Distinction is outstanding. For the CGPA, you will often see the CBSE rule of thumb that percentage ≈ CGPA × 9.5 — but that formula is specific to CBSE and does not transfer to every university, and it converts to a percentage, not directly to a 4.0 GPA. Some institutions also grade out of 4 already. An evaluator resolves all of this with an institution-specific table.
China: the 100-point scale to GPA
Chinese universities usually mark out of 100, with 60 as the pass line:
| Chinese mark | Common letter | Estimated GPA |
|---|---|---|
| 90–100 | A | 4.0 |
| 82–89 | B+ / B | 3.3–3.5 |
| 75–81 | B− | 2.7–3.0 |
| 70–74 | C+ | 2.3 |
| 60–69 | D | 1.0–2.0 |
| Below 60 | F | 0.0 |
The gotcha: what an 85 "means" varies a lot between Chinese institutions — some elite universities mark tightly and rarely award 90s, so an 85 there is more impressive than the same number elsewhere. The 60 pass line is a genuine floor: a mark in the low 60s is a modest pass, not a solid C. Because the spread differs so much by school, evaluators lean heavily on institution-specific scales for Chinese transcripts.
A worked example: estimating your GPA for a college list
Suppose you have mapped one semester's grades to US letters using the right table for your country. Now you need a single number. A US GPA multiplies each course's grade points by its credits, adds those up, and divides by total credits:
- Calculus — A (4.0) × 4 credits = 16.0 grade points
- Economics — A− (3.7) × 3 credits = 11.1 grade points
- World History — B+ (3.3) × 3 credits = 9.9 grade points
- Chemistry — B (3.0) × 4 credits = 12.0 grade points
Add the grade points: 16.0 + 11.1 + 9.9 + 12.0 = 49.0. Add the credits: 4 + 3 + 3 + 4 = 14. Divide: 49.0 ÷ 14 = 3.5 GPA.
Notice that the two four-credit courses pull harder on the result than the three-credit ones — that is credit weighting. In this example the credit-weighted GPA (3.5) happens to equal a plain average of the four letters, but when your heavier-credit courses carry different grades than your lighter ones, credit weighting shifts the number — and it is the more accurate method. This is also the difference between a raw GPA and the weighted GPA some US high schools report; our explainer on weighted vs unweighted GPA walks through the AP/IB/Honors bumps, which are US conventions and do not apply to most international transcripts.
Why there is no universal formula
Evaluators exist because the middle step, the actual conversion, is the hard part, and getting it right requires knowing your specific school. NACES members maintain detailed country and institution profiles — the reference standard many of them draw on is AACRAO EDGE (the American Association of Collegiate Registrars and Admissions Officers' Electronic Database for Global Education), which documents grading scales institution by institution. That is the level of specificity an official evaluation works from, and it is why no single table can be authoritative.
There is a second reason your self-estimate is only a starting point. US colleges routinely recalculate applicants' GPAs onto their own scale — dropping non-academic courses, re-weighting, and reading grades in the context of the school you attended. What moves an admissions decision is usually the rigor of your courses and your grade trend, not a single decimal — the kind of holistic reading emphasized across the US admissions field, including by the National Association for College Admission Counseling (NACAC). So use your estimate to decide where you fit and where to aim, then let the official process produce the number of record. To calibrate what your estimate even means in the US context, read what is a good GPA before you judge your own.
Frequently Asked Questions
How do I convert my percentage to a 4.0 GPA?
For a US-style percentage transcript, map each course to a letter grade (roughly 93+ = A/4.0, 83–86 = B/3.0, 73–76 = C/2.0), then average those points weighted by credits. But if your percentages come from a system where high marks are rare — the UK, India, much of Europe — do not use a US percentage band, because it will understate your record. Use your country's table, and treat the result as a planning estimate rather than an official figure.
What is ECTS to GPA?
ECTS is the European Credit Transfer and Accumulation System. "ECTS to GPA" usually means translating an ECTS letter grade (A–E) into US GPA points — a rough estimate is A ≈ 4.0, B ≈ 3.5, C ≈ 3.0, D ≈ 2.5, E ≈ 2.0. The catch is that ECTS grades are relative to a cohort and the European Commission's ECTS Users' Guide now favors grade-distribution tables over fixed percentiles, so the mapping is approximate. Note that ECTS credits (workload) are a separate thing from ECTS grades.
Is a self-calculated GPA official?
No. A GPA you calculate yourself — with any online tool, including ours — is an estimate for planning. It has no official standing for admissions, licensure, or immigration. For those, US institutions require a course-by-course evaluation from a NACES member such as WES, which produces a verified US-equivalent GPA using institution-specific reference data.
Do US universities accept WES?
Many do, and WES is one of the most widely recognized evaluators, but acceptance is not universal — some programs require a specific NACES member, a particular report type (course-by-course vs document-by-document), or their own in-house review. Always check the exact requirement on the program's admissions page before you order and pay for an evaluation.
What is a UK 2:1 in US GPA terms?
An upper second-class honours degree — a 2:1, typically 60–69% — is generally estimated at around a 3.3–3.7 GPA, often roughly a B-plus to A-minus. It is a strong result: in the UK system a 2:1 is the classification most competitive employers and graduate programs look for. As always, the precise US equivalent is set by the evaluator and your institution, not by a fixed formula.
How do US colleges use my converted GPA?
Usually as a starting point, not a verdict. Many colleges recalculate applicants' grades onto their own scale and read them through holistic review, so course rigor and your grade trend weigh more heavily than one decimal. Use your converted GPA to target realistic schools; the number of record comes from your official course-by-course evaluation and each college's own process.
Estimate your GPA for your college list
Once you have mapped your grades to US letters with the right table above, the arithmetic is the easy part — and you should not do it by hand. Our free GPA Calculator takes each course's letter grade and credit hours and returns a credit-weighted GPA on the US 4.0 scale, plus your total credits, so you can see instantly where your record lands and test different school choices.
Because it is a transcript you are working with, privacy matters: the calculator runs entirely in your browser. Nothing is uploaded, there is no sign-up or account, and no data is collected — you can enter every course from your degree and close the tab knowing none of it left your device. Use the number to build a realistic list and set your targets, and when it is time to apply for real, order your official course-by-course evaluation from a NACES member. The estimate gets you pointed in the right direction; the evaluation makes it count.
