Quick Answer & Understanding Your Result
A GPA Calculator computes Grade Point Average (GPA) across standard credit-weighted collegiate and high school grading scales.
International Grading Standards
- Unweighted 4.0 Scale (US/Global): Standard letter grade scale (A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0.0).
- 10.0 Metric Scale (Vietnam/Europe): Traditional linear percentage system converted to credit-weighted GPA.
- Credit-Hour Weighting: Multiplies each course grade point by course credit hours (Grade Points × Credits) divided by total credits.
Academic Applications
- Study Abroad Admissions: Converting Vietnamese 10.0 transcripts into US 4.0 scale for university applications.
- Graduation Honors: Tracking thresholds for Cum Laude, Magna Cum Laude, and Summa Cum Laude honors.
Enter your course grades and credit weights above to calculate your exact cumulative GPA instantly.
Formula & Calculation Logic
Mathematical FormulaWeighted average math:
- Multiplies each individual course grade point by its respective credit units.
- Divides the sum of all quality points by the total completed credit units.
