US GPA Scale Explained: 4.0 vs 5.0 vs Weighted (2026 Guide)

If you are planning to study in the United States, your GPA (Grade Point Average) is perhaps the most important number in your application. However, for many international students, the US grading system is confusing.

In this guide, we explain the different types of GPA scales and how they impact your 2026 admission cycle.

1. The Standard 4.0 Scale (Unweighted)

Most US universities use a 4.0 scale. In this system, each letter grade is assigned a number:

2. Weighted vs. Unweighted GPA

While the unweighted GPA treats all classes equally, the Weighted GPA gives more "weight" to difficult classes like AP (Advanced Placement) or IB (International Baccalaureate).

• Unweighted: Max is 4.0.
• Weighted: Can go up to 5.0 or even higher depending on the school's policy.

Universities look at both, but they often "recalculate" your GPA based on their own internal standards to ensure fairness.

3. How to Convert Your Local Grades

If you are coming from a system that uses percentages or a different scale (like the 10-point scale in India or the 5-point scale in some European countries), you usually shouldn't convert it yourself.

Professional agencies like WES (World Education Services) or ECE are often required by universities to provide an official "Course-by-Course" evaluation.
