How to Convert Grades Between International Systems
Every country grades students differently. The US uses letter grades (A through F), the UK uses degree classifications (First, 2:1, 2:2, Third), Australia uses descriptors (HD, D, CR, P, F), India uses its own letter system (O through F), Germany uses an inverted numeric scale (1.0 best to 5.0 fail), and Canada uses letters with different percentage cutoffs than the US. When you apply to study or work abroad, you need to translate your grades into a format the recipient understands.
1. Identify your source grading system and specific grade
2. Map your grade to a percentage range using your system’s official scale
3. Match that percentage to the equivalent grade in the target system
Example: UK 2:1 (65%) → US equivalent
UK 65% falls in the 2:1 band (60-69%)
On the US scale, this maps to B+ / GPA 3.3
Note: Direct percentage comparison is misleading.
A UK 65% is a strong result (2:1), but a US 65% is a D (barely passing).
Always use the classification mapping, not the raw number.
The critical mistake most students make is comparing raw percentages across systems. A 70% in the UK earns a First Class Honours, which is the highest classification. A 70% in the US is a C-minus, which is near the bottom of passing grades. The scales have different standards and distributions, so the grade name or classification is what matters, not the number itself. Our percentage to GPA calculator shows these differences in detail for numeric conversions.
Understanding Each Grading System
US Letter Grades (A-F)
The US system assigns letters from A+ (97-100%) down to F (below 60%). Each letter maps to a GPA value on the 4.0 scale: A and A+ both earn 4.0, B earns 3.0, C earns 2.0, D earns 1.0, and F earns 0.0. Plus/minus modifiers add or subtract 0.3 points (B+ = 3.3, B- = 2.7). This is the most commonly referenced system for international conversions because of its widespread use in admissions.
UK Degree Classifications
British universities use a classification system: First Class Honours (70%+), Upper Second or 2:1 (60-69%), Lower Second or 2:2 (50-59%), Third Class (40-49%), and Fail (below 40%). The percentage thresholds are lower than US equivalents because UK marking is deliberately conservative. Scoring above 80% is rare and exceptional. A student with a solid 2:1 has strong academic credentials comparable to a US B+ or A-.
Australian Grades (HD/D/CR/P/F)
Australian universities use High Distinction (80-100%), Distinction (70-79%), Credit (60-69%), Pass (50-59%), and Fail (0-49%). The percentage boundaries sit between the US and UK systems. Our GPA scale converter handles the numeric 7-point Australian GPA scale if you need to convert GPA numbers rather than letter classifications.
German Grading (1.0-5.0)
Germany uses an inverted numeric system where 1.0 is the best grade and 5.0 is a fail. The scale runs: Sehr Gut / Very Good (1.0-1.5), Gut / Good (1.6-2.5), Befriedigend / Satisfactory (2.6-3.5), Ausreichend / Sufficient (3.6-4.0), and Nicht Bestanden / Fail (4.1-5.0). A German 1.3 is roughly an American A-minus, while a German 3.0 maps to a US C+. The inverted logic trips up many students, so always remember: lower is better in Germany.
Indian Grading System
Indian universities use their own letter grades: O (Outstanding, 90-100%), A+ (80-89%), A (70-79%), B+ (60-69%), B (50-59%), C (40-49%), P (Pass, 33-39%), and F (Fail). These map to a 10-point CGPA scale. Indian grades tend to have lower percentage cutoffs than US grades, so an Indian A (70%) is stronger than the raw number suggests. For CGPA conversions, use our GPA calculator to compute overall GPA after converting individual grades.
Canadian Grading System
Canada uses letter grades similar to the US but with lower percentage thresholds. In Ontario, an A starts at 80%, while in the US an A starts at 93%. Some provinces use different boundaries, and Quebec uses an entirely separate R-score system for CEGEP admissions. Canadian universities may also use a 4.3 GPA scale where A+ earns 4.3 instead of 4.0, giving top students a measurable advantage.
Common Mistakes When Converting Grades
- Comparing raw percentages across systems: A UK 65% is a 2:1 (strong result), but a US 65% is a D (near-fail). The same number means completely different things because grading standards differ. Always convert by classification or letter, never by raw percentage alone.
- Forgetting that the German scale is inverted: A German 2.0 is a good grade (equivalent to US B+), not a poor one. Students unfamiliar with the system sometimes assume higher numbers mean better grades. In Germany, 1.0 is perfect and 5.0 is a fail.
- Assuming Canadian grades equal US grades: While both countries use A-F letters, the percentage boundaries differ. A Canadian A might start at 80% or 85% depending on the province, while a US A starts at 93%. Converting a Canadian B+ directly as a US B+ can misrepresent your standing.
- Using a single conversion for all universities: Grading scales vary within countries. Australian universities may define Credit as 60-69% or 65-74%. UK percentage boundaries for a First can be 70% at one university and 72% at another. Always verify the specific institution’s scale when precision matters. Use our letter grade calculator to compute your exact grade from raw scores before converting.
