Short answer. On the common 4.0 scale, a 4.0 is about 93-100%, a 3.0 is about 83-86% and a 2.0 is about 73-76%. Schools set their own bands, so check yours.
The scale used here
There is no single law for this. The table below is the common US scale, and the tool uses it. When your GPA falls between two letters, the tool estimates a value between the middle of the two percent ranges.
| Letter | Percent | GPA |
|---|---|---|
| A | 93–100 | 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 |
A school may draw its lines in a different place. For an application, a university may ask for a conversion from your own school. Use this page for planning only.
Worked example
Example. A GPA of 3.5 sits between a B+ (87–89%) and an A- (90–92%). The estimate is about 90%.
Questions
Is a 3.0 GPA the same as 80%?
Not exactly. On this scale a 3.0 is a B, which is 83–86%. An 80% is a B-, or 2.7.
Why does my school say something different?
Schools choose their own cut-offs. Some use 90 for an A. Use your school's grading policy when it differs.
Can I convert a GPA from another country?
Not with this tool. It is for the US 4.0 scale. Grading systems in other countries do not map one to one.
