International Grade Converter
Convert academic grades between US, UK, European (ECTS), and Indian grading systems.
Useful for study abroad and international applications.
Grade scale conversion translates grades between different systems — letter grades (A, B, C), percentage scores, GPA (0–4.0 or 0–10), and international grading systems used around the world.
US Letter Grade to GPA (4.0 Scale):
| Letter Grade | Percentage | 4.0 GPA |
|---|---|---|
| A+ | 97–100% | 4.0 |
| A | 93–96% | 4.0 |
| A− | 90–92% | 3.7 |
| B+ | 87–89% | 3.3 |
| B | 83–86% | 3.0 |
| B− | 80–82% | 2.7 |
| C+ | 77–79% | 2.3 |
| C | 73–76% | 2.0 |
| C− | 70–72% | 1.7 |
| D+ | 67–69% | 1.3 |
| D | 63–66% | 1.0 |
| D− | 60–62% | 0.7 |
| F | Below 60% | 0.0 |
GPA Calculation Formula:
GPA = Sum(Grade points × Credit hours) / Total credit hours
Worked Example:
| Course | Credits | Letter Grade | Grade Points |
|---|---|---|---|
| Math | 3 | A (4.0) | 12.0 |
| English | 3 | B+ (3.3) | 9.9 |
| History | 2 | A− (3.7) | 7.4 |
| Chemistry | 4 | B (3.0) | 12.0 |
Total grade points = 41.3 ÷ 12 total credits = GPA: 3.44
International Equivalents:
| System | Equivalent to US “A” |
|---|---|
| UK | First Class (70%+) |
| Germany | 1.0–1.5 (scale inverted) |
| France | 16–20 / 20 |
| India | 90%+ (distinction) |
Practical Tips:
- Different institutions weight A+ differently, so check your school’s exact scale
- Weighted GPA adds 0.5–1.0 point for AP/IB courses; colleges recalculate to unweighted for comparison
Why every one of these conversions is approximate
Grading systems are not measuring the same thing, so no conversion between them is exact. They differ in what the marks are for, and that is a deeper problem than any lookup table can solve.
The clearest example is the UK. A British First Class degree starts at 70%, and to an American eye that looks like a C. It is not. UK marking treats the upper range as genuinely hard to reach: marks above 80 are rare and above 90 almost unheard of, because the scale reserves that space for work that is publishable rather than merely correct. An American percentage scale uses the whole range and expects good work to land in the nineties. Convert 70% literally and you turn a first-class degree into a passing grade, which is the single most common mistake on international applications.
Germany inverts the direction as well as the range: 1.0 is the best possible mark and 4.0 is the lowest pass, so a “4” means something close to the opposite of what it means in a US GPA. India adds another wrinkle, since many universities award a first class at 60% and a distinction at 75%, thresholds that would read as mediocre anywhere in the United States.
The practical advice: use a converter to get in the right neighbourhood, then let the receiving institution do the official conversion. Most admissions offices have their own table and will apply it regardless of what any calculator says. If you are submitting a transcript, send the original marks with the grading scale printed on it rather than a converted figure, because a converted number without its scale is the thing most likely to be read wrongly.
