How to Convert Korean GPA: 4.0, 4.3, 4.5 and Percentage Table
Confused by Korean GPA scales like 4.5 or 4.3? Learn how to accurately convert your grades to the US 4.0 scale or a 100% percentage score with our comparison charts and official tool guide.
Applying for a scholarship like GKS (Global Korea Scholarship) or submitting your resume to a Korean company? You will likely run into a confusing hurdle: the Korean GPA system.
Unlike many Western countries that use a 4.0 scale, South Korea's academic landscape is split between 4.5 and 4.3 scales, and many institutions require you to provide a "Percentage Score" (백분율) instead of a grade point average.
If you're staring at your transcript wondering how your 3.8 out of 4.5 stacks up, this guide is for you.

The three main GPA scales used in Korea (4.0, 4.3, and 4.5)

Understanding Korean GPA Scales: 4.0, 4.3, and 4.5
In South Korea, there is no "national standard" for GPA. Each university chooses its own scale, though the vast majority fall into one of these three categories:
4.5 Scale: The most common system. Used by the majority of private and public universities. An A+ is 4.5, and a C0 is 2.3.
4.3 Scale: Used by many top-tier and international-focused universities, including Seoul National University (SNU), Yonsei University, and Ewha Womans University. This system includes "minus" grades (e.g., A- is 3.7).
4.0 Scale: Rarely used as the primary scale by Korean universities but is often the required format for international applications (like US graduate schools).
[!IMPORTANT]
Because the 4.5 scale is the "default" for many Korean job portals and government forms, you will often need to convert your 4.0 or 4.3 GPA into a 4.5 equivalent.

While each university has its own internal mapping, the following table shows the generally accepted relationship between the different scales and their percentage equivalents.
Letter Grade | 4.5 Scale | 4.3 Scale | 4.0 Scale | Percentage (%) |
|---|---|---|---|---|
A+ | 4.5 | 4.3 | 4.0 | 100 |
A0 | 4.0 | 4.0 | 3.7 | 96-97 |
A- | - | 3.7 | 3.4 | 93-94 |
B+ | 3.5 | 3.3 | 3.1 | 89-90 |
B0 | 3.0 | 3.0 | 2.8 | 85-86 |
B- | - | 2.7 | 2.5 | 82-83 |
C+ | 2.5 | 2.3 | 2.2 | 79-80 |
C0 | 2.0 | 2.0 | 1.9 | 75-76 |
Note: This chart is an approximation. Some schools may weigh a 4.3 A+ higher or lower when converting to a 4.5 scale.
How to Convert GPA to Percentage (%)
The Percentage Score (백분율) is often more important than the GPA itself in Korea. For example, the GKS scholarship requires a minimum percentage score (usually 80%) rather than a specific GPA.
Method 1: Check Your Transcript (Most Accurate)
Most Korean universities automatically print the "Percentage Score" or "Original Score Average" at the bottom of the transcript. Always use the number printed on your official document as your primary score.
Method 2: The Linear Formula (Estimation)
If you need a quick estimate and your school doesn't provide a table, you can use a basic ratio:
(Your GPA / Scale Max) * 100
Example: (3.6 / 4.5) * 100 = 80.0%
[!CAUTION]
Many universities use a non-linear curve where an 80.0% might actually correspond to a lower GPA (like 2.8/4.5). Do not rely on simple math for official government or high-stakes job applications.

Pro Tips for International Students & Workers
1. Document Management
When converting grades, keep a copy of your university's official Grading Scale Description. This is usually found on the back of your transcript or on the university's Registrar website. It explains what an "A" means in their system, which is vital for foreign evaluations.
2. GKS Scholarship Applicants
If you are applying for the Global Korea Scholarship, you must use the official GKS conversion table provided in the application guidelines. They are very strict about using their specific table over any other calculator.
3. "Rounding" Matters
Never round up your GPA unless explicitly told to do so. If you have a 3.49 and the requirement is 3.50, rounding to 3.5 could be seen as falsifying documents in the eyes of strict Korean HR systems.
FAQ: Frequently Asked Questions
Q: Is a 3.0 out of 4.5 a good grade in Korea?
A: A 3.0/4.5 is roughly a "B" average (approx. 85%). While it's passing, many competitive graduate programs and major companies (like Samsung or Hyundai) look for 3.5/4.5 or higher.
Q: Can I convert my US 4.0 GPA to a Korean 4.5 scale?
A: Yes, using the Saramin or JobKorea tools mentioned above is the standard way to do this for employment. For university admissions, the school will usually perform its own evaluation of your foreign transcript.
Q: What if my university uses a 100-point scale instead of GPA?
A: Many schools in China and India use this. In this case, simply use your 100-point score as your "Percentage Score."
Conclusion
Understanding the Korean GPA system is essential for anyone looking to build a career or continue their education in South Korea. While the multiple scales (4.0, 4.3, 4.5) can be confusing, the Percentage Score is the universal language that connects them all.
When in doubt, always refer to your official transcript first, and use trusted portal tools for everything else!
