Notes:
- Not all schools use A+ or C− in GPA calculations — check your school’s grading policy.
- Some institutions use weighted GPAs, giving an extra 0.5–1.0 points for Honors/AP/IB classes.
- A GPA of 3.0 = B average, and 4.0 = straight A’s on an unweighted scale.
FAQs on Grade to GPA Converter
How do I convert letter grades to GPA?
You assign each letter grade a point value based on a 4.0 GPA scale. For example:
A = 4.0
B = 3.0
C = 2.0
D = 1.0
F = 0.0
Then, average the points across all your classes. If your school uses weighted grades (like for AP or Honors classes), you add extra points — usually +0.5 or +1.0.
What GPA is a B+?
A B+ usually equals 3.3 on a 4.0 scale.
If it’s an Honors or AP course, it might be worth 3.8 to 4.3 depending on your school’s weighting system.
What’s the highest GPA I can earn?
The highest possible unweighted GPA is 4.0 — that means straight A’s in regular classes.
But if your school uses a weighted scale, the GPA can go as high as 4.5 or even 5.0 if you’re taking all Honors or AP classes and getting A’s.
Is a 3.0 GPA good?
A 3.0 GPA is a solid B average, and it’s considered good in most high schools. It meets minimum requirements for many colleges, but competitive schools may prefer higher.
How do AP and Honors classes affect GPA?
They’re usually weighted, which means an A in an AP class might count as 5.0 instead of 4.0.
That can give you a GPA higher than 4.0 and boost your class rank — but only if you do well in the harder class.
Can I convert GPA back to letter grades?
Yes! Here’s a quick guide:
4.0 → A
3.7 → A−
3.3 → B+
3.0 → B
2.7 → B−
2.0 → C
1.0 → D
0.0 → F
