GPA to Percentage Calculator
To convert GPA to a percentage, the most common methods are (GPA ÷ 4) × 100 on a 4‑point scale, or GPA × 9.5 on India's 10‑point CGPA scale. Enter your GPA to convert it to a percentage.
Convert your GPA to a percentage — or a percentage to a GPA — in both directions. Enter a US 4.0 GPA, a UK honours mark, a Canadian or Australian GPA, or a grade from 20+ countries, and get the percentage, the US 4.0-scale GPA equivalent and the letter grade.
Choose what to convert from and to, type your grade, then press Convert — it works both ways.
How the international GPA converter works
Every country grades differently. The United States and Canada use a 4.0 GPA with letter grades; the United Kingdom and Ireland mark in percentages and award honours classes; Australia uses a 7-point scale, New Zealand a 9-point scale and Singapore a 5.0 CAP; Europe shares the ECTS A–F letters; France marks out of 20, the Netherlands out of 10, Italy out of 30, and Spain, Brazil and Mexico out of 10; Germany and Austria run an inverted 1.0–5.0 scale where 1.0 is best, Switzerland a 1–6 scale, and Russia and Poland compact 2–5 scales; China and Japan mark out of 100; and South Korea uses a 4.5 GPA. This tool converts whichever grade you have both ways — to a percentage and back — and directly between any two countries, showing the US 4.0 GPA, a letter grade and the UK class so you can compare like-for-like.
Because no two universities publish identical tables, every result is a careful approximation built from the published national grade bands. For official use — university applications or credential evaluation — always confirm with your institution or an evaluator such as WES or ECE.
How to calculate GPA to percentage
On the common 4.0 scale, the quickest formula is Percentage = GPA ÷ 4 × 100 (the same as GPA × 25), so a 3.5 GPA is about 87.5%. To convert a percentage to a GPA, reverse it: GPA = Percentage ÷ 25, so 80% is roughly a 3.2 GPA. This calculator uses the more accurate letter-grade bands rather than a flat multiply, and it also converts the UK, Canada, Australia and 20+ other systems — but the ÷ 4 × 100 rule is a handy mental estimate. Pick your country above, type your grade and press Convert to see the exact figure both ways. Working out the grade for a single class instead? The final grade calculator and the percentage calculator handle that.
International grade conversion table
| Percentage | US GPA (4.0) | Letter | UK class | Australia (7) |

| 50–59% | 1.0–2.0 | D | 2:2 / Third | P (4) |
| Below 50% | 0.0 | F | Fail | Fail |
Approximate — bands vary by university. Singapore, New Zealand, ECTS, France and Germany map onto the same percentage column (see the formulas below).
The formula for each system
The bands below are each country's national grade meaning. The calculator also shows a US-scale percentage and 4.0 GPA, which is often higher than the national mark — a UK First (70%) or a French 16/20 represents top performance and converts to a high US grade.
- United States / Canada (4.0): letter-grade bands — A = 4.0 ≈ 90%+, B = 3.0 ≈ 77%, C = 2.0 ≈ 65%. A quick estimate is Percentage ≈ GPA ÷ 4 × 100.
- United Kingdom: already a percentage — First 70%+, Upper Second (2:1) 60–69%, Lower Second (2:2) 50–59%, Third 40–49%.
- Australia (7-point): High Distinction 7 = 85%+, Distinction 6 = 75–84%, Credit 5 = 65–74%, Pass 4 = 50–64%.
- Singapore (5.0 CAP): A = 5.0 ≈ 80%+, B = 3.5 ≈ 65%, C = 2.0 ≈ 50%.
- New Zealand (9-point): A+ = 9 = 90%+, B = 5 ≈ 70%, C− = 1 ≈ 50%.
- Europe — ECTS: A ≈ top 10% (≈ 90%), B ≈ 80%, C ≈ 70%, D ≈ 62%, E = lowest pass ≈ 52%, F = fail.
- France (/20): 16–20 = très bien ≈ 90%+, 14–15 = bien ≈ 80%, 12–13 = assez bien ≈ 68%, 10–11 = passable (pass) ≈ 55%. French marking is strict, so marks above 16 are rare.
- Germany (1.0–5.0, inverted): 1.0 = best ≈ 95%, 2.0 ≈ 80%, 3.0 ≈ 64%, 4.0 = lowest pass ≈ 50%, 5.0 = fail.
- Netherlands (1–10): 10 ≈ 98%, 8 = very good ≈ 84%, 6 = pass ≈ 71%; grades above 8 are rare.
- Italy (exam /30): 30 e lode ≈ 96%, 27 ≈ 87%, 24 ≈ 77%, 18 = pass ≈ 58%.
- Spain, Brazil & Mexico (0–10): 10 ≈ 98%, 9 = excellent (sobresaliente) ≈ 91%, 7 ≈ 75%, 5–6 = pass.
- Switzerland (1–6): 6 ≈ 97%, 5 = good ≈ 80%, 4 = pass ≈ 62%; a 6 is almost never awarded.
- Russia & Poland (2–5): 5 = excellent ≈ 92%, 4 = good ≈ 77%, 3 = pass ≈ 64%, 2 = fail.
- China & Japan (0–100): marks are already percentages — 90+ is excellent and 60 the usual pass, so they are used as entered.
- South Korea (4.5 GPA): 4.5 = A+ ≈ 97%, 4.0 = A ≈ 91%, 3.0 = B ≈ 81%, 2.0 = C ≈ 71%.
Worked examples (both directions)
US 3.5 GPA → percentage: about 84–85% on the US scale (roughly a UK 2:1 and an Australian Distinction). Germany 2.0 → US GPA: about 3.7 — the same level as an Australian Distinction (6.0) or a UK First. Straight across: a German 2.0 converts to an Australian 6.0; an ECTS A is roughly a US 3.9 GPA; and a UK First (70%) maps to about a US 3.7 GPA — not 2.5, because a UK 70 is top performance, not a literal 70%.
How to use it & key terms
Pick what you're converting from and to, enter your grade, then press Convert for the equivalent percentage, US 4.0 GPA and class.
| Term | What it means |
|---|---|
| GPA | Grade point average, commonly on a 4.0 US scale. |
| CGPA | Cumulative GPA — your overall average across all terms. |
| Percentage | A 0–100 mark used in many countries. |
| WAM | Weighted average mark (Australia), already expressed as a percentage. |
| ECTS grade | The European A–F statistical grading scale. |
| Class / honours | Degree bands such as First, 2:1 or Distinction. |
| Credential evaluation | Official conversion by bodies like WES for applications. |
Sources & methodology
Each grade is mapped to a common US-scale percentage — the percentage a US university would associate with that level of performance — and from there to the US 4.0 GPA, a letter grade and the UK honours class by piecewise interpolation. This is why the US-scale percentage can differ from your national mark: a UK First (70%) or a German 1.7, though numerically lower, reflects top performance and maps to a high US grade. The same interpolation runs in reverse, so any system converts to any other; inverted scales (Germany) and letter scales (ECTS) are handled separately.
Sources: Cross-checked against credential evaluators and published equivalency tables — WES and ECE guidance, Scholaro, the OMSAS / OzTrekk conversion charts (Canada & Australia), gpacalculator.net, and university equivalency tables such as the University of Manitoba's — covering the US / Canada 4.0 scales, UK & Ireland honours, the Australian 7-point scale, Singapore CAP, the New Zealand 9-point scale, ECTS, France (/20), Germany (1–5), the Netherlands (1–10), Italy (/30), Spain / Brazil / Mexico (0–10), Switzerland (1–6), Russia / Poland (2–5), China / Japan (0–100) and South Korea (4.5).
Common mistakes when converting grades between countries
A converted grade is a translation, not a fact, and the most common errors come from treating it like one. The biggest is assuming a percentage means the same thing everywhere. In the United States a 60% is often a weak, near-failing mark, while a 60% in the United Kingdom is a First — the very top class. Read one country's number through another country's expectations and you will either sell yourself short or overstate where you stand. The same trap catches people who compare raw percentages from two systems side by side and conclude that a "lower" number is worse, when in fact it may sit at the top of its own scale. A grade only means something next to the scale it came from.
Direction is the next stumble. Several systems run "upside down" compared with the four-point GPA: in Germany 1.0 is excellent and higher numbers are worse, and letter or class scales such as ECTS don't line up neatly with a percentage at all. Convert in the wrong direction and a strong result can look like a poor one. Two more mistakes are quieter but just as costly — mixing a weighted GPA (padded by honours or advanced courses) with the unweighted four-point figure that most conversions expect, and rounding your own average up before converting, which compounds into a bigger gap once it is mapped onto another scale. Small input errors do not stay small after a conversion.
The last and most important mistake is treating any converted number as official. Admissions offices, employers and credential evaluators almost always recalculate from your actual transcript, course by course, using their own tables — so the figure a quick tool gives you is a sensible guide for setting expectations, not something to quote as fact. Use a conversion to see roughly where you stand and which programmes are realistic, keep your original transcript and its native grades as the real record, and confirm the exact equivalence with the institution or evaluator that will actually make the decision. Treated that way, the number is genuinely useful; treated as gospel, it misleads.
- Same number, different meaning — a 60% is not the same grade in every country.
- Watch the direction — some scales rank 1 as best and count upward for worse.
- Compare like with like — use the unweighted GPA, and don't round before converting.
Frequently asked questions
How do I convert GPA to percentage (and back)?
Choose what you are converting from and to, enter your grade, and press Convert. It works both ways — grade to percentage or percentage back to a grade — and also directly between countries, for example a US GPA into an Australian 7-point grade. Every result shows the equivalent percentage, US 4.0 GPA and letter class, and is an approximation, so confirm with your university or WES for official use.
How do I convert a US 4.0 GPA to a percentage?
On the US 4.0 scale, 4.0 ≈ 90%+ (A), 3.0 ≈ 77% (B) and 2.0 ≈ 65% (C). A quick approximation is Percentage = GPA ÷ 4 × 100, but letter-grade bands are more accurate — which is what this tool uses.
How do I convert a UK degree classification to a percentage or GPA?
UK degrees are marked as percentages: First 70%+, Upper Second (2:1) 60–69%, Lower Second (2:2) 50–59%, Third 40–49%. A First is roughly a 3.7–4.0 US GPA and a 2:1 about 3.3–3.7.
How do I convert an Australian 7-point GPA to a percentage?
High Distinction (7) = 85–100%, Distinction (6) = 75–84%, Credit (5) = 65–74%, Pass (4) = 50–64%. Some universities report a WAM, which is already a percentage.
Which countries and grading systems does it support?
It covers more than 20 systems: the US and Canada (4.0 GPA), the UK and Ireland (honours %), Australia (7-point), New Zealand (9-point), Singapore (5.0 CAP), the EU (ECTS A–F), Germany and Austria (1–5), France (/20), the Netherlands (1–10), Italy (/30), Spain, Brazil and Mexico (0–10), Switzerland (1–6), Russia and Poland (2–5), China and Japan (0–100) and South Korea (4.5 GPA). Pick your country under “Convert from”.
How do European ECTS grades and the French /20 scale convert?
ECTS is a statistical A–F scale where A ≈ top 10% (about 90%) down to E as the lowest pass (about 52%). France marks out of 20, where 16+ is très bien (≈ 90%) and 10 is the pass mark (≈ 55%); French marking is strict, so high marks are rare.
Why is the German grade scale backwards?
In Germany 1.0 is the best grade and 5.0 is a fail, with 4.0 the lowest pass — the opposite of most systems. In US terms, roughly 1.0 ≈ a 4.0 GPA, 2.0 ≈ 3.7, 3.0 ≈ 3.0 and 4.0 (the lowest pass) ≈ 1.7. The calculator inverts the scale for you.
Can I convert a percentage back into a GPA?
Yes. Set “Convert from” to Percentage and “Convert to” to any system — US 4.0 GPA, Australian 7-point, German grade and so on — to run the conversion in reverse. You can also convert directly between two countries. Or just tap the Swap direction button to flip any conversion instantly.
Are these grade conversions exact?
No — they are careful approximations based on published national grade bands. Every country, and often every university, has its own official table, and evaluators like WES or ECE use their own method. Always confirm the exact figure with your institution.
What is the US 4.0 GPA equivalent used for?
The US 4.0 GPA is the most widely recognised reference, so the tool shows it beside the percentage. It helps when applying to US or Canadian universities, or when a form asks for your GPA on a 4.0 scale regardless of where you studied.
How do I convert a percentage to a GPA on the 4.0 scale?
For a quick estimate, divide your percentage by 25 — 80% is about 3.2 and 90% about 3.6 on the 4.0 scale. For a more accurate figure, set “Convert from” to Percentage and “Convert to” to United States or Canada, and the calculator maps your percentage to the 4.0 GPA using letter-grade bands.
Can I use this as a CGPA to percentage calculator?
Yes. CGPA simply means your cumulative grade point average — your overall GPA. Enter it as a US 4.0 GPA (or pick your country's scale) under “Convert from” and choose Percentage under “Convert to”. The reverse turns a percentage back into a CGPA on the 4.0 scale.
How do I convert CGPA to percentage on India's 10-point scale?
On India's CBSE 10-point scale, the standard formula is percentage = CGPA × 9.5. For example, a CGPA of 8.0 is about 76%, and 9.2 is about 87.4%. Enter your CGPA and convert to a percentage to check the exact figure.
How do I convert CGPA to GPA?
If your CGPA is on a 10-point scale (common in India), convert it to a US 4.0 GPA in two steps: turn it into a percentage first (many Indian universities use percentage ≈ CGPA × 9.5), then map that percentage onto the 4.0 scale. Set “Convert from” to your country's scale and “Convert to” to United States, and the calculator does both steps for you.
What is a 3.8 GPA in percentage?
On the US 4.0 scale, a 3.8 GPA is roughly 90–92% (an A− to A). It's not a fixed multiplication — it depends on your school's letter-grade bands — so the quick GPA ÷ 4 × 100 gives 95%, which overstates it. Enter 3.8 as a US GPA and convert to a percentage for the calculator's figure.
