GPA Converter
Uses a typical unweighted 4.0 scale. Percent bands vary by school. Weighted values cap at 5.0 and aren’t added to an F.
Converts one course grade using this page’s example scale. Honors and AP/IB values illustrate +0.5 and +1.0 bonuses, with no bonus for an F. Your school’s cutoffs and weighting rules may differ.

4.0 GPA Scale Chart
This example 4.0 GPA scale includes plus and minus grades. Match your course grade to its grade-point value, then use your course credits to calculate your overall GPA. Percentage cutoffs vary by school.
| Letter grade | Example percentage range | Grade points |
|---|---|---|
| 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 | 65–66% | 1.0 |
| D− | 60–64% | 0.7 |
| F | Below 60% | 0.0 |
This chart uses A+ = 4.0. Some schools award a different value for A+, omit plus/minus grades, or use different percentage boundaries. Follow your school’s grading and rounding rules when calculating an official GPA.
Understanding the GPA Scale
Grade points describe a single course grade. GPA combines the grades from the courses included in your school’s calculation.
| Term | Meaning |
|---|---|
| Letter grade | The grade awarded for a course, such as A, B+, or C. |
| Percentage grade | A score expressed out of 100. Your school’s cutoffs determine its letter-grade equivalent. |
| Grade points | The numerical value assigned to a letter grade, such as 4.0 for an A on this page’s scale. |
| GPA | The average of the included course grade points, accounting for course credits when applicable. |
What Does GPA Scale Reporting Mean?
GPA scale reporting identifies the grading scale your school uses—not the GPA you earned. For example, a 3.6 GPA on a school-reported 4.0 scale uses 4.0 as the scale and 3.6 as the cumulative GPA.
Use your transcript or your counselor’s instructions when completing an application. Report weighted or unweighted status separately when requested; do not infer the school’s reporting scale solely from whether your GPA exceeds 4.0.
How GPA Scales Work
Unweighted GPA Scale
An unweighted GPA does not add bonus points for course difficulty. Using this page’s chart, a B+ is worth 3.3 grade points whether the course is regular, Honors, or AP.
Unweighted does not necessarily mean every course counts equally. A school may still weight each course by its credits when calculating the overall GPA.
Weighted GPA Scale
A weighted GPA adds extra grade points to eligible advanced courses. This example adds 0.5 for Honors and 1.0 for AP or IB courses, with no bonus for an F.
These are the example bonuses used by this page’s converter, not rules followed by every school. Course eligibility, bonuses, and maximum values depend on your school’s policy.
| Letter grade | Regular | Honors: +0.5 example | AP/IB: +1.0 example |
|---|---|---|---|
| A+ | 4.0 | 4.5 | 5.0 |
| A | 4.0 | 4.5 | 5.0 |
| A− | 3.7 | 4.2 | 4.7 |
| B+ | 3.3 | 3.8 | 4.3 |
| B | 3.0 | 3.5 | 4.0 |
| B− | 2.7 | 3.2 | 3.7 |
| C+ | 2.3 | 2.8 | 3.3 |
| C | 2.0 | 2.5 | 3.0 |
| C− | 1.7 | 2.2 | 2.7 |
| D+ | 1.3 | 1.8 | 2.3 |
| D | 1.0 | 1.5 | 2.0 |
| D− | 0.7 | 1.2 | 1.7 |
| F | 0.0 | 0.0 | 0.0 |
These are per-course grade points, not a conversion of your entire GPA. Some schools restrict weighting for lower grades or use a different calculation.
What About a 4.3 GPA Scale?
A 4.3 scale may award 4.3 points for an A+ without adding a bonus for course difficulty. Stanford uses this approach. A GPA above 4.0 therefore does not automatically mean it is weighted; check how the school assigns grade points.
How to Convert Grades to GPA
Start by converting each course grade to grade points using your school’s scale. Then multiply each grade-point value by the course credits, add the results, and divide by the total credits included in your GPA.
GPA = Total quality points ÷ Total GPA credits
Quality points are the grade points for a course multiplied by its credits.
Example: Courses With Different Credits
| Course | Letter grade | Credits | Quality points |
|---|---|---|---|
| English | A | 3 | 4.0 × 3 = 12.0 |
| Art | B | 1 | 3.0 × 1 = 3.0 |
| Total | 4 | 15.0 |
Calculation:
15.0 ÷ 4 = 3.75 GPA
Simply averaging 4.0 and 3.0 would give 3.5, which would be incorrect for this credit-weighted example. Averaging course grade points directly works only when all included courses count equally.
For percentage grades, convert each course percentage separately before calculating GPA. Using this page’s example chart, 90% and 92% both correspond to A− and 3.7 points, while 93% corresponds to A and 4.0 points. An overall percentage average is not necessarily equivalent to a GPA calculated course by course.
GPA Scale – FAQs
Is GPA always on a 4.0 scale?
No. Schools may use a 4.0 scale, an A+-based 4.3 scale, weighted scales such as 5.0 or 6.0, or another grading system. Use the scale stated by your school rather than assuming every GPA is out of 4.0.
Is an A+ worth 4.0 or 4.3?
It depends on the school. This page’s chart assigns 4.0 to both A and A+. Some institutions, including Stanford, assign 4.3 to an A+. Your school’s grading policy determines the value used in your official GPA.
What GPA points are A, A−, B+, B, and B− worth?
On this page’s 4.0 scale, A = 4.0, A− = 3.7, B+ = 3.3, B = 3.0, and B− = 2.7. These are values for individual course grades; your overall GPA depends on all included grades and credits.
What percentage equals a 4.0 GPA?
In this page’s example chart, course grades from 93–100% receive 4.0 points. Other schools may use different cutoffs. A cumulative 4.0 GPA does not identify one exact percentage average, because different course percentages can receive the same grade-point value.
How do I convert a weighted GPA to an unweighted 4.0 GPA?
Recalculate from your course grades without the advanced-course bonuses, using the applicable grade-point and credit rules. A weighted GPA alone is not enough to determine an exact unweighted GPA. Dividing by 5 and multiplying by 4 does not generally remove course-specific weighting.
Can I convert my overall GPA back to a percentage?
Not to one exact percentage in general. Different combinations of course grades can produce the same GPA, and percentage cutoffs vary. A chart can show example grade ranges, but it cannot reconstruct the original marks.
What is a good GPA on a 4.0 scale?
On this page’s scale, 3.0 corresponds to B-level grade points and 4.0 to A-level grade points. Whether a GPA meets your goal depends on the requirements of your school, program, scholarship, or application, not a universal cutoff.
Do colleges use the same GPA scale as my high school?
Not necessarily. Colleges may review the GPA your school reports or recalculate it using their own course-selection and weighting rules. Follow each application’s instructions when reporting grades and GPA.
