Reference conversion rules
| Source → Target | Method | Example |
|---|---|---|
| 4.0 → 4.3 | A+ (4.0) → 4.3, rest same | 3.7 → 3.7, 4.0 → 4.3 |
| 4.0 → 5.0 | Linear: score / 0.8 | 3.6 → 4.5 |
| 4.3 → 4.0 | Capped at 4.0 | 4.3 → 4.0, 3.7 → 3.7 |
| 5.0 → 4.0 | Linear: score × 0.8 | 4.5 → 3.6 |
| 10-Point → 4.0 | Linear: CGPA × 0.4 | 8.5 → 3.4 |
| Percentage → 4.0 | Standard US lookup table | 85% → 3.0 |
| UK Degree → 4.0 | First ↔ 3.7–4.0, 2:1 ↔ 3.0–3.6, 2:2 ↔ 2.5–3.0, Third ↔ 2.0–2.5 | 2:1 → 3.3 |
Why there is no single correct answer
Grading scales differ not only between countries but between institutions within the same country. A "percentage" at one Chinese university may be calculated differently at another; an Australian 7-point scale has different descriptors per state. US admissions teams are used to this — many recalculate your GPA themselves from your official transcript, and some ask for a WES (or similar) evaluation. Use this converter to get a ballpark figure for your own planning.
Frequently asked questions
How do I convert 4.0 to 4.3 scale?+
Select source '4.0 GPA' and target '4.3 GPA'. The converter maps each letter grade to its 4.3 equivalent: A+ (4.0) → 4.3, A (4.0) → 4.0, A- (3.7) → 3.7, B+ (3.3) → 3.3, and so on since Canadian 4.3 scales differ only at the A+ tier. Note that not all Canadian universities award A+ in the same way — some cap at 4.0 regardless.
How do I convert a 5.0 GPA to 4.0?+
We use the linear reference formula GPA = score × 0.8. A 4.5 on a 5.0 scale becomes 3.6 on a 4.0 scale. This is a rough reference — Chinese 5.0 scales vary by university (some use a modified 5.0 where max is 4.0 for regular courses but 5.0 for major courses).
How do I convert a 4.0 GPA to a 5.0 scale?+
We use the reverse linear reference: GPA = score / 0.8. A 3.6 on a 4.0 scale becomes 4.5 on a 5.0 scale. Again, this is a rough reference — some Chinese universities use a different mapping entirely.
How do I convert UK degree class to US GPA?+
First Class Honours → 3.7–4.0 (typically treated as 3.7+), Upper Second (2:1) → 3.0–3.6, Lower Second (2:2) → 2.5–3.0, Third Class → 2.0–2.5. This varies by US university — some treat a 2:1 as a 3.0, others as a 3.3. Always check the specific university's conversion policy.
How do I convert US GPA to UK degree class?+
Roughly: 3.7+ → First Class, 3.0–3.6 → Upper Second (2:1), 2.5–2.9 → Lower Second (2:2), 2.0–2.4 → Third Class. UK universities typically review your transcript directly rather than using a conversion formula.
Is this GPA converter accurate for university applications?+
There is no official, universal formula for converting between grading scales. Every university and credential evaluation service (WES, ECE, etc.) uses its own method. Use this tool as a quick reference estimate, not as an official conversion.
Can I convert 10-point CGPA to 4.0 GPA?+
Yes. Select source '10-Point CGPA' and target '4.0 GPA'. We use the linear reference: GPA = CGPA × 0.4. This is the most common reference used by US admissions offices as a quick check for Indian applicants, but it is not an official UGC or government standard.
Can I convert percentage to GPA?+
Yes. Select source 'Percentage (100-point)' and target '4.0 GPA'. We use the standard US grading table: 93–100 → 4.0, 90–92 → 3.7, 87–89 → 3.3, and so on. Note some schools use slightly different cut-offs.
How this calculation actually works
Why there is no universal GPA conversion standard
Every "GPA converter" on the web — including this one — has to make a choice that no official body has ever made: pick a single formula that works for every country. The reason is that grading systems are defined by individual institutions, not by countries. A "percentage" at Peking University follows a different mark scheme than a "percentage" at the University of Mumbai, and neither one maps to the US 4.0 scale the same way the other does.
When the US 4.0 scale was adopted across American universities in the mid-20th century, each school set its own grade-point-to-letter cut-offs. The table we use on this page — 93–100% → A → 4.0 — is the most common variant, but it is not universal. The University of Florida, for example, does not award A+ at all, and Florida State University counts A+ as 4.33. Neither is wrong; they are simply different.
What professional evaluators do differently
Credential evaluation agencies like WES (World Education Services),ECE (Educational Credential Evaluators), and SpanTrando not use a single formula either. They look at your original transcript — course by course, mark by mark — and map each one to the US 4.0 scale using the country-specific and institution-specific guidance they maintain. A WES evaluation for an Indian 10-point CGPA of 8.5 will not simply multiply by 0.4; it will examine the issuing university's grading scale, the year of the transcript, and the course level.
When to use a professional evaluation instead
Many US graduate programmes require a course-by-course evaluation from a NACES-member agency (WES, ECE, IEE, etc.). If the application portal says "WES evaluation required" or "foreign credential evaluation", this converter will not substitute for it. Use this tool to get a ballpark figure for your own planning — and then budget for the official evaluation.
