How to Use This Letter Grade to GPA Calculator
A transcript full of letter grades looks clean until you need one decimal GPA for an application, a scholarship form, or a quick what-if semester calculation. Manually assigning point values down a long list is where simple typos turn a B+ into a 3.0 instead of 3.3. Select your letter from the dropdown and press Convert—the tool returns the exact unweighted grade point this site uses everywhere else.
- Choose a letter. Options include plus/minus variants from A+ / A through F.
- Convert. The primary result shows grade points; the secondary line states the mapping in words.
- Build a semester GPA. For multiple courses with credits, switch to the GPA Calculator.
- Go the other direction. Have a numeric GPA and need the letter band? Use the GPA to Letter Grade Calculator.
Letter Grade to GPA Formulas and Practical Applications
This is a translation table, not algebra—each letter maps to a fixed decimal on the 4.0 scale, like exchanging currency at a posted rate. A B+ is always 3.3 here; a plain B is 3.0. Once you know the points, you can multiply by credits and sum for a semester total—the same method the College GPA Calculator automates.
In our testing, the most common use is checking a single grade before entering a row in a spreadsheet, verifying what an advisor quoted, or teaching students how plus/minus letters change the numeric average even when the letter "looks" similar.

Frequently Asked Questions
Does an A+ give more points than an A?
On this unweighted scale both cap at 4.0. Some colleges award 4.3 for A+ separately—confirm with your registrar.
What if my school uses weighted honors or AP grades?
Honors bumps (for example B → 4.0 instead of 3.0) are not applied here. Add your school's bonus after you look up the base points, or use weighted mode in the GPA Calculator.
