How the conversion works
This calculator converts a numeric grade into a letter grade (A-F) and a qualitative rating, using common percentage bands.
Conversion table
| Range (%) | Letter | Rating |
|---|---|---|
| 90–100% | A | Excellent |
| 70–89% | B | Good |
| 50–69% | C | Fair |
| 30–49% | D | Poor |
| 0–29% | F | Poor |
0-10 or 0-100 scale
Pick the scale your school uses. A 7.5 on the 0-10 scale equals 75 on the 0-100 scale — both fall in the "B / Good" band.
Important note
Every institution may use its own conversion criteria. Treat this result as a general reference, not a substitute for your school's official grading policy.
Frequently asked questions
Is this conversion an official standard?
No — these are common reference bands. Each school or institution may use its own conversion criteria.
What's the difference between the 0-10 and 0-100 scale?
None proportionally — 0-100 is simply the 0-10 scale multiplied by 10.
What rating does a 6.0 on the 0-10 scale get?
It becomes "C / Fair", since 6.0 equals 60%, within the 50-69% band.
Can I use this table for grades from another country?
You can use it as a general reference, but passing criteria vary widely between countries and institutions.
