Convert GPA values to letter grades instantly. See which letter grade your GPA falls under with our complete mapping on the 4.0 scale.
Your GPA is a number, but sometimes you need to express it as a letter grade — for scholarship applications, transfer evaluations, or simply to understand where you stand. This converter maps any GPA value on the 4.0 scale to its corresponding letter grade using standard academic thresholds.
Enter your GPA and instantly see the equivalent letter grade. The tool also shows the GPA ranges for all letter grades so you can see how close you are to the next tier. A 3.68 GPA might feel like a B+, but it's just 0.02 away from an A−.
This converter uses the most common US academic mapping. Note that individual institutions may define slightly different ranges, so always verify with your registrar's office for official conversions.
Students, parents, and educators all gain valuable perspective from precise gpa to letter grade data when planning academic paths, managing workloads, or setting realistic performance goals. Return to this calculator each semester or grading period to stay on top of evolving academic targets.
GPA-to-letter conversion isn't always intuitive. While A=4.0 and B=3.0 are easy, the plus/minus boundaries (3.3 for B+, 3.7 for A−) require looking up. This tool does the lookup instantly and shows the full table for reference. Real-time results let you test different scenarios instantly, helping you set achievable goals and build an effective plan for academic success.
Standard GPA to Letter Grade Ranges: 3.70–4.00 = A / A− 3.30–3.69 = B+ 3.00–3.29 = B 2.70–2.99 = B− 2.30–2.69 = C+ 2.00–2.29 = C 1.70–1.99 = C− 1.30–1.69 = D+ 1.00–1.29 = D 0.70–0.99 = D− 0.00–0.69 = F
Result: B+
A 3.45 GPA falls in the B+ range (3.30–3.69). You are 0.25 points below the A− threshold of 3.70. Raising your GPA by earning a few more A grades could push you into A− territory.
The 4.0 scale divides into letter grade ranges that help communicate performance. The A range (3.7–4.0) represents excellent work. B range (2.7–3.69) represents above average. C range (1.7–2.69) is average. D range (0.7–1.69) is below average, and F (below 0.7) indicates failure.
Some contexts require letter grade equivalents rather than GPA numbers. International applications, certain scholarship forms, and employment applications sometimes ask for letter grade standing. This converter bridges the gap instantly.
The B+ range (3.30–3.69) is notably wide, spanning 0.39 GPA points. Many students plateau here before breaking through to A− territory. Understanding that 3.70 is the threshold helps set a concrete target for improvement.
A 3.5 GPA corresponds to a B+ on the standard scale. It's above a B (3.0–3.29) but below an A− (3.70–4.00). This is typically good enough for Dean's List.
An A− corresponds to a 3.7 grade point value, and the A− range is typically 3.70–3.99 on the GPA scale.
The 4.0 scale is standard, but the exact GPA range for each letter grade can vary slightly between institutions. The ranges shown here are the most commonly used version.
You need 3.70 or higher for an A− and 3.85+ for a solid A at most institutions. Some define A as 3.93–4.00 with A− at 3.70–3.92.
On a standard unweighted scale, 4.0 is the maximum. On a weighted scale (with AP/Honors bonuses), GPAs can exceed 4.0 but don't have standard letter grade equivalents above A+.
A GPA below 0.70 (or in some definitions below 1.0) corresponds to an F. A 0.0 GPA means all courses received F grades.
