If you’re trying to convert GPA to CGPA accurately, the most reliable method is a credit-weighted CGPA calculation. Different universities follow different grading rules, but the core formula stays the same: multiply each course/semester GPA by its credits, add everything, then divide by total credits.
This GPA to CGPA Converter is designed in an international-friendly way. You can calculate CGPA using Manual GPA (recommended for maximum accuracy), or you can choose a common grading scheme like US Letter (4.00) or ECTS (approx.) and let the calculator auto-fill GPA values.
How GPA to CGPA Calculation Works
CGPA is not a simple average of GPAs unless every course has the same credit value. Most institutions use a weighted system.
Formula:
CGPA = Σ(GPA × Credits) ÷ Σ(Credits)
Example
If you took 3 courses:
- Course 1: GPA 3.70, Credits 3
- Course 2: GPA 3.30, Credits 3
- Course 3: GPA 3.00, Credits 2
Weighted points = (3.70×3) + (3.30×3) + (3.00×2)
Total credits = 3+3+2
CGPA = Weighted points ÷ Total credits
This is exactly what the calculator does—so your result matches real university transcripts.

GPA vs CGPA: What’s the Difference?
