How it works
We match your percentage to the standard US grading band, then read off the GPA assigned to that band:
Percentage → Letter grade → GPA (4.0 scale)This is the same lookup most US colleges publish. If your school uses different cutoffs, the GPA may shift by 0.1–0.3 in either direction.
Example calculation
You finish a class with an 88% average. 88% falls in the 87–89% band, which is a B+ on the standard scale. A B+ is worth 3.3 GPA points. So your GPA for that class is 3.3.
