Read a GPA number back as a letter
A GPA is a tidy number, but it hides the letter grade behind it. If your transcript shows a 3.42 term average, or a scholarship form asks for the letter equivalent of your 2.7, this converter closes that gap: enter a GPA between 0.0 and 4.0 and it returns the letter grade that value lands on. Select a letter instead and it shows the exact grade-point value schools assign it — the number they plug into every GPA calculation.
This is most useful when you are translating between two systems that describe the same performance. A registrar reports GPA points; a professor hands back a paper marked B+; a graduate application wants a letter. Because a GPA is a continuous number and letters are fixed categories, the converter uses standard midpoint thresholds so a 3.5 and a 3.7 both read as an A-, while a 3.9 tips over into an A.
Letter Grade to GPA Chart (4.0 Scale)
The table below shows every letter grade and its corresponding GPA value on the standard US 4.0 scale. This is the scale used by most American high schools and colleges for unweighted GPA calculations.
| Letter Grade | GPA Points (4.0 scale) |
|---|---|
| A | 4.0 |
| A+ | 4.0 |
| A- | 3.7 |
| B+ | 3.3 |
| B | 3.0 |
| B- | 2.7 |
| C+ | 2.3 |
| C | 2.0 |
| C- | 1.7 |
| D+ | 1.3 |
| D | 1.0 |
| D- | 0.7 |
| F | 0.0 |
A+ and A both map to 4.0 on the standard scale. Some institutions assign A+ = 4.3 — check your school's grading policy.
How to Convert GPA to a Letter Grade
The GPA-to-letter mapping uses threshold values. A GPA of 3.85 or higher is an A; 3.5–3.84 is an A-; 3.15–3.49 is a B+; and so on. Because GPA is a continuous number while letter grades are discrete categories, there is a range of GPA values that all map to the same letter grade.
To convert in the other direction — from letter grade to GPA — each letter has a fixed point value on the 4.0 scale (e.g. B = 3.0, C+ = 2.3). This is what institutions use to compute your semester and cumulative GPA.

Worked Examples
A 3.5 term GPA
3.5 sits exactly on the A- threshold, so the converter returns A-. This is the classic "almost an A" result: it means your grades averaged out to the bottom edge of the A-minus band. Nudge the average up to 3.85 and it becomes a straight A; slip to 3.14 and it drops to a B.
A 2.9 semester average
It is tempting to round 2.9 down to "a B-minus," but the threshold for a plain B is 2.85, and 2.9 clears it. So a 2.9 reads as a B, not a B-. This is where a mental round-off trips people up — the bands are set at midpoints (2.85, 3.15, 3.5), not at the whole and half numbers you might expect.
Turning a single B+ back into points
Going the other direction, select B+ and the tool shows 3.3 grade points. That is the value a school multiplies by the course's credit hours when it builds your GPA — a 3-credit B+ contributes 3.3 × 3 = 9.9 quality points. Do that for every course, divide by total credits, and you get the GPA that this converter reads back as a letter.
Tips & Common Mistakes
- A cumulative GPA is not a single grade. A 3.42 does not mean you earned a "3.42" in any course — it is the average of many letters. The letter this tool returns is the closest single equivalent, useful for context, not a grade that appears on any one transcript line.
- A+ and A both read as 4.0. The standard scale caps the top at 4.0, so entering 4.0 returns an A and there is no way to recover an A+ from the number alone. A handful of schools award A+ a 4.3 — if yours does, trust your official transcript over any converter.
- Watch the midpoint thresholds. The cutoffs sit between the letters (for example 3.15 splits B from B+, and 2.5 splits B- from C+). A 3.14 is a B and a 3.15 is a B+ — a hundredth of a point apart. Small rounding in how your school stores GPA can flip the letter.
- Weighted GPAs above 4.0 do not fit. Honors and AP bonuses can push a weighted GPA past 4.0, but this converter tops out at 4.0. Convert to an unweighted equivalent first, or use the weighted GPA calculator to see how the bonus points are applied.
Frequently Asked Questions
How do I convert a GPA to a letter grade?
Match your GPA to the nearest band on the 4.0 scale: 3.85–4.0 = A, 3.5–3.84 = A-, 3.15–3.49 = B+, 2.85–3.14 = B, and so on down to F at 0.0–0.49. Enter your GPA above and the converter returns the letter grade instantly.
What letter grade is a 3.0 GPA?
A 3.0 GPA corresponds to a B on the standard 4.0 scale. It represents an 80–89% average and is generally considered the minimum for competitive graduate school applications and many scholarships.
What letter grade is a 3.5 GPA?
A 3.5 GPA falls in the A- range on the plus/minus scale (3.5–3.84). On the basic five-letter scale it rounds to an A. It represents a strong academic record and is often the benchmark for honours, Dean's List, and competitive programmes.
What GPA is an A, and what is an A-?
On the standard US plus/minus scale, an A maps to 4.0 GPA and an A- maps to 3.7 GPA. Both require a grade in the 90%+ range, though the exact percentage cutoff for A vs A- varies by school (commonly 93% for A, 90% for A-).
Why does an A+ still show as 4.0 GPA?
On the most common US 4.0 scale both A and A+ are capped at 4.0 — there is no numerical distinction at the top. Some institutions award A+ a value of 4.3 or 4.33 as an exception; if your school uses that policy, use your official transcript or registrar's GPA calculation.
