GPA to Letter Grade
A GPA maps back to a range of letters, not to one letter. The chart below is the usual 4.0-scale reading; the calculator applies it to your number.
The usual chart
GPA does not convert back to a single letter grade, because many different letter combinations average to the same number. What it converts to is a range. This is the common 4.0-scale reading:
| GPA | Letter | GPA | Letter |
|---|---|---|---|
| 3.85–4.00 | A | 2.35–2.64 | C+ |
| 3.65–3.84 | A− | 1.85–2.34 | C |
| 3.35–3.64 | B+ | 1.65–1.84 | C− |
| 2.85–3.34 | B | 1.35–1.64 | D+ |
| 2.65–2.84 | B− | 0.85–1.34 | D |
| 0.65–0.84 | D− | ||
| below 0.65 | F |
A GPA above 4.0 means a weighted scale. The calculator converts it to its 4.0 equivalent first (a 4.2 on a 5.0 scale is about 3.36) and then reads the band, because the letter bands above are defined on the 4.0 scale.
Why one GPA covers many letters
A 3.46, for example, could come from this transcript:
| Course | Grade | Points | Credits | Quality |
|---|---|---|---|---|
| Statistics | B+ | 3.3 | 3 | 9.9 |
| Microeconomics | A− | 3.7 | 3 | 11.1 |
| Biology | B | 3.0 | 4 | 12.0 |
| Philosophy | A | 4.0 | 3 | 12.0 |
| Total | — | 13 | 45.0 |
45.0 ÷ 13 = 3.46, which falls inside the B+ band — but two of the four courses were graded A or A−. Swap the 4-credit biology B for a C+ (2.3) and the same student lands at 3.24, a straight B. The average hides both facts, which is why transcripts list the letters and not just the number.
What to report to whom
- Applications: give the GPA with the scale — "3.46/4.0" — and never a bare letter. A letter invites the reader to assume a band you did not claim.
- Resumes: the GPA alone is usually enough for a new graduate; after a few years of work, most people drop it.
- Scholarship forms: if they ask for a letter, ask which band they use. A 3.5 is an A− at one school and a B+ at another, depending on whether plus/minus grades exist.
Common questions
Is a 3.5 GPA an A?
Not on the standard table: A starts at 3.7 (A−) or 3.85 (A). A 3.5 is a B+ band. At a school that ignores plus/minus grades, though, 3.5 is literally an A/B mix, and the school may describe it that way.
Does a 3.5 round up to a 4.0?
No. GPAs are not rounded to whole numbers for any purpose that matters; transcripts report two decimals and admissions readers compare two decimals.
Why does my school call my 3.5 an A average?
Because that school's table has A = 4.0, B = 3.0 and no plus or minus steps, so a mix of A's and B's lands between 3.0 and 4.0 and gets described loosely. The band chart above assumes a school that does use plus/minus grades.
How do I get from a letter back to a GPA?
You need the credits as well as the letters, because GPA is credit-weighted. The GPA calculator takes each course's letter and credits and returns the number.
