GPA to Letter Grade Conversion Chart
Instantly convert between GPA numbers and letter grades — in both directions.
A 3.5 GPA equals a B+/A− letter grade (roughly 90–92%). A 3.0 GPA equals a B (83–86%). A 2.0 GPA equals a C (73–76%). Conversions vary slightly by institution, but the standard 4.0 scale is used by most US colleges and high schools.

Understanding the GPA Points Scale
The standard 4.0 scale assigns numeric values to letter grades for the purpose of calculating a grade point average. Some important nuances:
- A+ and A both equal 4.0 in most U.S. grading systems. Getting an A+ earns distinction within the class but doesn't numerically boost your GPA beyond a regular A.
- No partial credit between grades — a high B+ (89%) and a low B+ (87%) both earn exactly 3.3 GPA points. The GPA system groups grades into bands.
- Weighted scales can exceed 4.0 — AP and IB courses add up to 1.0 bonus, so an A in AP earns 5.0 weighted points. See our weighted GPA calculator.
GPA Thresholds That Matter
- 4.0 — Perfect GPA; all A's
- 3.9+ — Summa Cum Laude threshold at most schools
- 3.7+ — Magna Cum Laude; letter grade equivalent ≈ A−
- 3.5 — Dean's List; Cum Laude; letter grade ≈ B+/A−
- 3.0 — Minimum for most graduate programs; letter grade = B
- 2.0 — Minimum passing/good standing; letter grade = C
Frequently Asked Questions
What letter grade is a 3.5 GPA?
A 3.5 GPA is a B+/A− average — equivalent to roughly 90–92%. It is considered an excellent GPA that qualifies for Dean's List at most schools and is competitive for most graduate programs.
What letter grade is a 3.0 GPA?
A 3.0 GPA equals a B letter grade — roughly 83–86%. It is the standard "good standing" threshold at most US colleges and the minimum for many graduate program applications.
What letter grade is a 2.7 GPA?
A 2.7 GPA corresponds to a B− letter grade, equivalent to about 80–82%. It is above average at many schools but falls below the 3.0 minimum required by most graduate programs.
What letter grade is a 2.0 GPA?
A 2.0 GPA is a C average, equivalent to 73–76%. It is the minimum GPA for good academic standing at most universities. Falling below 2.0 typically triggers academic probation.
How do you convert a percentage grade to GPA?
90–100% = 3.7–4.0 (A−/A), 80–89% = 2.7–3.3 (B−/B+), 70–79% = 1.7–2.3 (C−/C+), 60–69% = 1.0–1.3 (D/D+), below 60% = 0.0 (F). Exact conversions vary slightly by institution.
Is a 3.7 GPA an A or A−?
A 3.7 GPA corresponds to an A− letter grade, equivalent to 90–92%. A full A (93–100%) earns a 4.0. The 0.3 difference between A− and A can matter significantly over a full college career.
