How international grade conversion works
There is no single universal GPA. A 85% average from China, a First-Class from the UK, a German 2.3 and a 4.3 on a 5.0 scale all mean different things to an admissions committee. This converter normalizes each grade into US 4.0 grade points, then computes the credit-weighted average — the same principle used by agencies like WES when they build a course-by-course evaluation.
Two rules make a big difference to your final number:
- Weighting matters. A 4-credit core course moves your GPA much more than a 1-credit elective. Enter the credits exactly as printed on your transcript.
- Use the scale your transcript shows. If your Chinese transcript lists raw percentage marks, convert with the 100-point scale. If it only shows 5.0 grade points, use the 5.0 scale. Mixing systems within one transcript inflates the error.
Key Takeaways
- There is no universal GPA. A 85% from China, a UK First-Class, and a German 2.3 each represent different levels of achievement. Standardizing to the US 4.0 scale lets you compare your standing across systems.
- Credit weighting matters. A 4-credit core course has four times the impact of a 1-credit elective. Always enter credits exactly as shown on your transcript.
- Use the scale your transcript shows. If your transcript lists percentages, use the 100-point scale. If it lists 5.0 grade points, use the 5.0 scale. Do not mix systems.
- This tool is an estimate. It is not an official WES evaluation. Universities and credential agencies apply their own conversion policies.
- The Bavarian formula for German grades is: US GPA = 1 + 3 × (5 − g) ÷ 4, where g is your German grade (1.0 = best).
- For Chinese students: 90–100 → 4.0, 85–89 → 3.7, 82–84 → 3.3, 78–81 → 3.0, 75–77 → 2.7, 72–74 → 2.3, 68–71 → 2.0, 64–67 → 1.5, 60–63 → 1.0, below 60 → 0.0.
Country-Specific Conversion Guides
Each country and region uses its own grading scale. Below are the conversion rules this calculator applies for each system.
China — 100-Point Percentage Scale (百分制)
Chinese universities grade on a 0–100 percentage scale. A score of 60 is the minimum passing grade. The conversion to US 4.0 follows these bands: 90–100 = 4.0 (equivalent to an A average), 85–89 = 3.7, 82–84 = 3.3, 78–81 = 3.0, 75–77 = 2.7, 72–74 = 2.3, 68–71 = 2.0, 64–67 = 1.5, 60–63 = 1.0, and below 60 = 0.0 (fail). This scale is also used for Indian and Iranian transcripts.
India — Percentage to GPA Conversion
Indian universities also use the 100-point scale. The CGPA-to-percentage conversion varies by university, but for US admissions purposes, the same 100-point bands above apply. A 90% aggregate typically maps to a 4.0 US GPA.
United Kingdom — Honours Classification
UK degrees are classified as First-Class (70%+), Upper Second 2:1 (60–69%), Lower Second 2:2 (50–59%), and Third (40–49%). This tool uses the midpoint of each band: First ≈ 3.85, 2:1 ≈ 3.5, 2:2 ≈ 3.0, Third ≈ 2.35. Note that UK 3.0 is roughly equivalent to a US 2.7–3.0.
Germany — 1.0 to 5.0 Scale (Bavarian Formula)
German grades run from 1.0 (best) to 5.0 (fail). The Bavarian (modified) formula converts to US 4.0: US GPA = 1 + 3 × (5 − g) ÷ 4. A German 1.0 = 4.00 US, 1.7 ≈ 3.48, 2.0 ≈ 3.25, 2.5 ≈ 2.88, 3.0 ≈ 2.50, 3.7 ≈ 1.98, 4.0 ≈ 1.75. Grades above 4.0 are failing and count as F (0.0).
Singapore and Other 5.0-Scale Systems
Some Chinese and Singaporean universities use a 5.0 grade-point scale. The simple conversion is US GPA ≈ 5.0-scale GPA − 1.0. A 4.3/5.0 becomes approximately 3.3 US. If your transcript also lists raw percentages, converting from percentages usually gives a more accurate result.

WES-style conversion FAQ
The questions students most often ask when preparing a WES or equivalent credential evaluation.
What is WES and do I need an official evaluation?
WES (World Education Services) is an independent credential evaluation agency. Many US and Canadian universities require international applicants to submit an official WES ICAP or course-by-course evaluation before they compute your GPA. This online calculator is a free estimate only — it cannot replace an official report.
How do I convert my Chinese 100-point average to a US 4.0 GPA?
Use the 100-Point Percentage system above and enter every course with its credits. The tool maps 90–100 → 4.0, 85–89 → 3.7, 82–84 → 3.3, 78–81 → 3.0, 75–77 → 2.7, 72–74 → 2.3, 68–71 → 2.0, 64–67 → 1.5, 60–63 → 1.0 and below 60 → 0.0, then weighs each converted point by credits.
What US GPA is a UK First-Class or 2:1 degree equivalent to?
- First-Class (70%+) ≈ US 3.7 – 4.0
- Upper Second 2:1 (60–69%) ≈ US 3.3 – 3.7
- Lower Second 2:2 (50–59%) ≈ US 2.7 – 3.3
- Third (40–49%) ≈ US 2.0 – 2.7
Agencies apply their own banding — the calculator uses each class midpoint as a single representative value.
What is the Bavarian formula for German grades?
The Bavarian (modified) formula converts a German grade g (1.0 best, 4.0 pass, above 4.0 fail) to US 4.0: US GPA = 1 + 3 × (5 − g) ÷ 4. German 1.0 → 4.00, 2.0 → 3.25, 2.5 → 2.88, 3.7 → 1.98, 4.0 → 1.75. This tool counts German grades above 4.0 as F (0.0).
Is a 5.0-scale GPA just "US GPA + 1.0"?
Not exactly. The simple rule US ≈ 5.0-scale GPA − 1.0 (e.g. 4.3 / 5.0 ≈ 3.3 US) is a common estimate, and that is what this tool applies per course. Many Chinese universities award 5.0-scale grade points from raw percentages, so if your transcript lists both, converting from the raw percentage scale usually gives a more defensible number.
How are A+, A− and B+ treated on the 4.0 scale?
Standard US 4.0: A+ and A both = 4.0, A− = 3.7, B+ = 3.3, B = 3.0, B− = 2.7, C+ = 2.3, C = 2.0, C− = 1.7, D = 1.0, F = 0.0. Note: some Canadian schools award A+ = 4.3. Always match the calculator to the legend on your own transcript.
Do failed courses count in my GPA?
In this tool, below 60 (100-point) or above 4.0 (German) converts to 0.0 / F and lowers the GPA, matching how many transcript evaluations treat repeated failures. Universities differ on repeated courses (some average both attempts, some count only the higher one) — check each school's policy. Many German programs exclude failed attempts you retake.
How do I convert credits from ECTS or quarter credits to US semester credits?
As a rough rule: 1 US semester credit ≈ 15–16 contact hours, and 1 ECTS credit ≈ 0.5 US semester credit. You do not need to re-enter credits here — just be consistent: the GPA is computed from the credits you type, so keep every course on the same credit convention as your transcript.
Is this an official WES iGPA calculator?
No. This is an independent free estimator for quick reference. WES runs its own official iGPA calculator and sells credential evaluations. For application documents, only an official evaluation from WES or another NACES-member agency is accepted as proof.
What is a good GPA for international students applying to US universities?
For US graduate admissions, a GPA of 3.0 is the minimum threshold for most programs. Competitive programs (Top-50) typically expect 3.3–3.5+, while elite programs (Top-20, Ivy League) often look for 3.7+. For undergraduate admissions, requirements vary more widely — many international students convert their home-country grades to demonstrate equivalency.
How do I convert my Indian CGPA to US GPA?
Indian universities use percentage-based grading. Use the 100-Point Percentage system in this tool: 90–100% → 4.0, 85–89% → 3.7, 80–84% → 3.3, 75–79% → 2.7, 70–74% → 2.3, 65–69% → 2.0, 60–64% → 1.0, below 60% → 0.0. Some Indian universities also issue a 4.0 or 10-point CGPA — in that case, convert each course's percentage rather than the CGPA directly.
What is the difference between WES and ECE?
WES (World Education Services) and ECE (Educational Credential Evaluators) are both NACES-member agencies that provide official credential evaluations for international students. WES is the most widely recognized for US admissions. ECE is often preferred for Canadian applications and immigration. Both charge similar fees ($200–$350) and take 2–8 weeks. This converter provides estimates only — neither WES nor ECE accepts it as documentation.
Can I convert my GPA without logging in?
Yes. This GPA converter runs entirely in your browser. There is no login, no account, and no data submission. All calculations happen locally on your device. You can close the page and your grades are gone — nothing is stored.
How do quarter credits convert to semester credits?
US universities use semester credits (typically 120–128 for a bachelor's degree). Quarter credits convert at roughly 3 quarter credits = 2 semester credits. So 45 quarter credits ≈ 30 semester credits. Check your transcript — some universities list both. Enter the credit value that matches your transcript's system for consistent GPA calculation.
What is the ECTS credit system and how does it convert?
ECTS (European Credit Transfer System) is used across European universities. One ECTS credit represents approximately 25–30 hours of student work. For US conversion, 1 ECTS credit ≈ 0.5 US semester credits. A typical European bachelor's degree (180 ECTS) equals about 90 US semester credits. This tool does not auto-convert credits — enter your credits as listed on your transcript.
Does retaking a course improve my GPA?
It depends on the university policy. Some institutions replace the original grade with the retake grade in GPA calculations. Others average both attempts. A few count only the highest grade. In this tool, each row is a separate course entry — if your university averages retakes, you would need to enter both attempts and weight them accordingly. Check your registrar's policy.
