How to convert Stony Brook University grades
Select a conversion type, choose or enter one value, and click Convert. Letter-grade and grade point conversions are exact: a result is returned only when that mapping exists in the table above.
This converter does not calculate a semester or cumulative GPA. GPA calculations use multiple courses and their credit values, which is why they remain on the separate GPA calculator pages.
About this Stony Brook University grading data
The converter reads the university-specific grading table used across BetterCollegeGrades.com. It does not use a generic country-wide scale and does not estimate a grade when the required mapping is absent.
Terminology: This page uses “Grade Points” for the numerical value assigned to an individual grade. Some U.S. institutions use “quality points” for a credit-weighted total rather than the single value assigned to a grade, so this converter keeps the per-grade label as “Grade Points.”
