Percent to GPA converter

Kroma

Enter a percentage, a letter grade or a GPA and see the matching letter, 4.0 scale GPA and percent range. On the common US scale, 93–96 is an A (4.0), 90–92 an A− (3.7), 87–89 a B+ (3.3) and 83–86 a B (3.0). Honors courses add 0.5 and AP courses add 1.0 to the weighted value.

📌 Key facts

  • On the common US scale, 93 to 96 is an A (4.0), 90 to 92 an A- (3.7), 87 to 89 a B+ (3.3) and 83 to 86 a B (3.0).
  • Below 60 is usually an F (0.0) on a 4.0 scale.
  • Honors courses usually add 0.5 and AP courses 1.0 to a weighted GPA.
  • There is no single national conversion chart: each school or district sets its own cutoffs.
  • Colleges may recalculate your GPA with their own formula, often using only core academic classes.

Percent, letter grade and GPA chart

Most US high schools and colleges convert a percentage to a letter, then to GPA points on a 4.0 scale. This is the most common chart:

PercentLetterGPA
97–100A+4.0
93–96A4.0
90–92A−3.7
87–89B+3.3
83–86B3.0
80–82B−2.7
77–79C+2.3
73–76C2.0
70–72C−1.7
67–69D+1.3
63–66D1.0
60–62D−0.7
0–59F0.0

Some schools stop at \( A = 4.0 \) without a plus, others give an \( A + 4.3 \), and some use a flat 90/80/70/60 scale with no plus or minus.

Weighted values for honors and AP classes

Weighted GPAs reward harder classes. The common method adds 0.5 for honors and 1.0 for AP, IB or dual-enrollment courses, only when the grade is passing. An A (4.0) becomes 4.5 in an honors class and 5.0 in an AP class, a B (3.0) becomes 3.5 or 4.0.

\[ \text{weighted GPA} = \text{base GPA} + 0.5\ \text{(honors)}\ \text{ or }\ {+}\,1.0\ \text{(AP/IB)} \]

To combine several classes into one GPA, use the GPA calculator, which also weighs each class by its credits.

How colleges look at converted grades

Admissions offices usually recalculate your GPA from your transcript using their own rules, often counting only core academic classes and ignoring weighting. Your school's reported GPA is what appears on your transcript, so use this converter to estimate, not to replace it.

International students can convert grades to a US-style GPA with a credential evaluation service, since a 14/20 or a first-class degree does not map to a US letter by simple arithmetic.

Percent to GPA: the standard conversion chart

Most US high schools use a chart like this one. Check your own school's version, because cutoffs vary.

PercentLetterGPA
97 to 100A+4.0
93 to 96A4.0
90 to 92A-3.7
87 to 89B+3.3
83 to 86B3.0
80 to 82B-2.7
77 to 79C+2.3
73 to 76C2.0

So an 88% maps to a B+ and a 3.3.

Percent to GPA: when your school differs

Some schools use a 90-80-70 scale with no plus or minus. Others weigh classes on a 5.0 or 100-point scale. Therefore, always ask your counselor for the official table.

  • Pass or fail classes usually do not count.
  • International grades need a separate conversion.
  • Repeated courses may replace or average with the old grade.

Also, if you moved between schools, each transcript keeps its own scale, and the college combines them.

Percent to GPA: how colleges read converted grades

Admissions officers care about trends and course rigor, not only a single number. For example, a 3.6 in advanced classes can impress more than a 4.0 in easy ones.

Next, they look at the context: your school's grading culture and the classes it offers. Finally, many colleges recalculate your GPA from the core subjects, so your converted number is a guide, not an official score.

When you convert a grade, write down the method you used. That way you can explain it if someone asks.

Percent to GPA: tools that work together

After the conversion, average your whole transcript with the GPA calculator. To plan the last test of the term, use the final grade calculator. For class categories with different weights, open the weighted average calculator. Then, the percent change calculator shows your growth across terms.

Percent to GPA: a quick checklist

Before you use a percent to GPA conversion, run a short checklist. First, find your school's official chart. Next, convert each class one at a time. Then average the results by credits. Finally, save the percent to GPA table you used.

For example, a 91% in chemistry becomes an A- worth 3.7. A percent to GPA tool saves time, but your registrar's number always wins. Also, if a class uses a curve, convert the final percentage and not the raw one. A percent to GPA result is only as good as the chart behind it.

3 real-life examples

1

A 91.5% in chemistry

91.5 falls in the 90–92 band: A−, 3.7. In an honors class the weighted value is 4.2; in AP it is 4.7.

2

From a 3.5 GPA to a letter

3.5 sits between \( B + (3.3) \) and A− (3.7). The converter returns the letter just below it: B+, which covers 87–89%.

3

Average of three class percentages

95% (A, 4.0), 85% (B, 3.0) and 75% (C, 2.0) give \( \dfrac{4.0 + 3.0 + 2.0}{3} = \) 3.0 GPA with equal credits.

Frequently asked questions

How do I convert a percentage to GPA?
Find the letter grade for the percentage, then read its points on the 4.0 scale. For example 88% is a B+, which is 3.3. Enter the percentage above for the instant result.
What percent is a 4.0 GPA?
A 4.0 corresponds to an A, usually 93% and up. Some schools start the A at 90%, and an A+ (97% and up) is also 4.0 on most scales, although a few give it 4.3.
What GPA is an 85%?
An 85% is a B on the usual scale, which is a 3.0. Under a scale without plus or minus, 80–89% is also a B, 3.0.
How is a weighted GPA converted?
Add 0.5 for honors and 1.0 for AP or IB to the base GPA when the course grade is passing. An A in AP counts as 5.0 and a B in honors as 3.5.
Is this the scale my school uses?
It is the most common one, but schools set their own. Check your student handbook or transcript key for the exact table, especially for plus and minus grades.
