Letter Grade to GPA Reference Guide
The letter grading system is the most recognisable measure of academic performance in the United States. Letter grades are assigned based on percentage scores and then converted to GPA points for the purpose of calculating grade point averages. Understanding these conversions is essential for students tracking their academic progress or applying to graduate programs.
Why Does the Same Letter Have Different GPA Values?
On a standard 4.0 scale, both A and A+ are worth 4.0 — the scale doesn't go higher. On a 5.0 scale used in weighted grading (common in high school AP courses), each grade earns one additional point, making an A worth 5.0 instead of 4.0. This is why comparing GPA values between students from different schools requires context about which scale each school uses.
Frequently Asked Questions
Is a B+ the same as 3.3 GPA everywhere?
The B+ = 3.3 equivalence is the most widely used standard in the US, but not universal. Some institutions use slightly different conversions — for example, treating B+ as 3.5 instead of 3.3. Always check your institution's official grading scale. For graduate school applications, most programs will recalculate your GPA using their own conversion if needed.
My school doesn't use +/− grades — how do I convert?
If your school uses a simplified A/B/C/D/F scale without plus or minus, use the middle values: A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0.0. When entering your GPA on applications, note that your school uses a simplified scale, which is common and fully understood by admissions committees.
