Enter a percentage to see the GPA it earns, or switch to GPA to see the percentages behind it. The same percentage gives different GPAs at different schools, so you’ll see three published tables side by side instead of one number.

Why one percentage gives different GPAs
Here are six common percentages run through each table, plus the shortcut of dividing by 100 and multiplying by 4 in the last column.
| Percentage | University of Toronto | Chowan University | College Board chart (whole letters) | Shortcut (÷100 × 4) |
|---|---|---|---|---|
| 95% | 4.00 | 4.00 | 4.00 | 3.80 |
| 85% | 4.00 | 3.00 | 3.00 | 3.40 |
| 80% | 3.70 | 2.70 | 3.00 | 3.20 |
| 75% | 3.00 | 2.00 | 2.00 | 3.00 |
| 70% | 2.70 | 1.70 | 2.00 | 2.80 |
| 65% | 2.00 | 1.00 | Not listed | 2.60 |
Why not just multiply by 4?
Take 80%. Toronto gives 3.70, the College Board chart gives 3.00, and Chowan gives 2.70. The shortcut gives 3.20, which doesn’t match any of them. Schools set bands, so a range of percentages earns one GPA, and the bands aren’t spread evenly across the scale. Dividing by 100 treats every percentage point as the same fraction of a grade point, which none of these three tables does.
A worked example
Say a course ended on 84.5%. In each table the decimal sits with the whole number below it, so 84.5 is treated as 84.
| Table | Band for 84% | GPA | Letter |
|---|---|---|---|
| University of Toronto | 80 to 84% | 3.70 | A- |
| Chowan University | 83 to 86% | 3.00 | not given |
| College Board chart (whole letters) | 80 to 89% | 3.00 | B |
The answer is 3.00 to 3.70. Two of the three tables agree on 3.00, and Toronto is 3.70. If you are applying to a school that publishes its own table, use that one. If it doesn’t, give the marks as they are and let the school convert them.
How the conversion works
- Each table lists percentage ranges and the GPA each range earns. Find the range your percentage falls in.
- Read off the GPA for that range. If you have a decimal like 84.5, it sits in the range of the whole number below it, so 84.5 is in the 80 to 84 range.
- Do the same in every table to see how much the answer depends on the school.
- To go the other way, find the grade point in the table and read off the percentage range that earns it.
Assumptions to keep in mind
- The three tables are examples of what real schools and the College Board publish. They are not an official standard, and no table is more right than another.
- Your school or the school you are applying to may use its own table. If it publishes one, that table beats anything on this page.
- Percentages are treated as whole-number bands, which is how the tables are written. A 79.6 sits in the 77 to 79 band, not the 80 band.
- The tables stop at a 4.0 GPA. Some schools give an A+ more than 4.0, and this page does not.
- The College Board chart skips 65 to 65.99. If you land there, the page says it is not listed rather than guessing.
Mistakes that throw a conversion off
Multiplying by 4
Dividing by 100 and multiplying by 4 is the shortcut a lot of converters use. It gives 3.2 for 80%, which none of the published tables here do. It can look right for a high mark and be well off for a middle one.
Using one school’s table for another school
Toronto’s 80% is a 3.7 and Chowan’s 80% is a 2.7. Use the table of the school you are applying to, if it publishes one.
Converting when you were told not to
Many schools ask for your grades as they are, and convert them themselves. Check the application instructions before you submit a converted number.
Forgetting the GPA is an average
A percentage for one course converts to a grade point for that course. Your GPA is the credit-weighted average of those, so convert each course, then use the GPA calculator.
Treating the estimate as official
Some schools send marks to a credential evaluator, such as WES or ECE, who use their own method. An evaluator’s number is the one that counts if your school asks for one.
Questions students ask
What is 80% as a GPA?
It depends on the table. It’s a 3.7 at the University of Toronto, a 3.0 in the College Board chart and a 2.7 at Chowan University. That spread is why there’s no single answer.
Is 75% a 3.0 GPA?
At Toronto, yes, because 73 to 76 is a B worth 3.0. In the College Board and Chowan tables 75% is a 2.0, because their 70s sit lower. Check the table that matters for your application.
Do I need to convert my percentage before I apply?
Often not. Many schools ask for your marks as they are and convert them themselves, and some use a credential evaluator. Check the application instructions first, because a number you convert yourself may not be accepted.
Why isn’t it percentage divided by 100 times 4?
Because no school in these tables does it that way. Schools set bands, so a range of percentages earns one GPA, and the bands are not evenly spread. 80% would be a 3.2 by the shortcut and a 2.7, 3.0 or 3.7 in the real tables.
How do I convert a GPA back to a percentage?
Switch to GPA above and enter it. You get the range of percentages that earns that GPA in each table. A GPA covers a band, so you get a range and not one number.
