How to Convert GPA to a Letter Grade
A GPA on the 4.0 scale maps directly to a letter grade. Enter your GPA and this calculator shows the matching letter, along with the percentage range that letter usually represents. It uses the standard US grading scale, where each grade point value corresponds to a letter and a percentage band.
GPA to Letter Grade Chart
Here is the standard conversion between GPA values, letter grades, and percentages on the 4.0 scale:
- 4.0 = A or A+ (93-100%)
- 3.7 = A- (90-92%)
- 3.3 = B+ (87-89%)
- 3.0 = B (83-86%)
- 2.7 = B- (80-82%)
- 2.3 = C+ (77-79%)
- 2.0 = C (73-76%)
- 1.7 = C- (70-72%)
- 1.3 = D+ (67-69%)
- 1.0 = D (63-66%)
- 0.7 = D- (60-62%)
- 0.0 = F (below 60%)
Frequently Asked Questions
A 3.5 GPA falls right at the boundary and converts to an A minus on the standard 4.0 scale. It represents roughly a 90 to 92 percent average, which is a strong result often described as an A minus student.
A 3.0 GPA is a B on the 4.0 scale, equal to about an 83 to 86 percent average. This is considered good standing at most schools and is a common benchmark for scholarships and program eligibility.
On the standard 4.0 scale, both A and A plus are worth 4.0 grade points, so a 4.0 GPA can be either. Some schools use a 4.3 or higher scale where an A plus is worth more than 4.0, but the common unweighted scale caps at 4.0 for both.
A GPA is an average, so it often lands between whole letter values. For example, a 3.4 sits between a B plus (3.3) and an A minus (3.7). This calculator rounds to the nearest letter grade using the midpoint between values, so a 3.4 shows as a B plus.
This calculator uses the standard unweighted 4.0 scale. Weighted GPAs from honors, AP, or IB courses can exceed 4.0 and do not map cleanly to a single letter, since the extra points reward course difficulty rather than a higher letter grade. For a weighted GPA, the letter shown here reflects the 4.0-scale equivalent.
