Korean GPA Scales: Quick Answer
When preparing for admission to universities in the US or Europe, one confusing aspect is the GPA (Grade Point Average) system. Korea typically uses a 4.5 or 4.3 scale, while the US standard is 4.0.
A Korean GPA should be calculated as a credit-weighted average: add each course's grade points multiplied by its credits, then divide by the total graded credits. A simple ratio such as 3.0 ÷ 4.5 × 4.0 is not an official US credential conversion because institutions can apply different policies.
| Scale | Typical maximum | Common context |
|---|---|---|
| Korean 4.5 | A+ = 4.5 | Widely used by Korean universities |
| Korean 4.3 | A+ = 4.3 | Used by some Korean universities |
| US-style 4.0 | A/A+ = 4.0 | Common in the United States |
Calculate your credit-weighted Korean GPA
Why Use a GPA Calculator?
- Standardization: Different schools have different "perfect" scores. A standardized conversion is needed for fair comparison.
- Scholarship Applications: Many scholarships require a GPA on a 4.0 scale.
- Resume: Global companies often request a standard GPA.
How to Convert Correctly
Using the ConverterGo Korean GPA Calculator, enter each course's credits and letter grade, then choose the grading scale printed on your transcript.
Major Scales
- 4.5 Scale: Common in many Korean universities.
- 4.3 Scale: Used by Seoul National University, Yonsei, etc.
- 4.0 Scale: The standard American scale.

Worked Example
Suppose you completed three graded courses:
| Course | Credits | Grade on a 4.5 scale | Weighted points |
|---|---|---|---|
| Course A | 3 | A+ (4.5) | 13.5 |
| Course B | 3 | A0 (4.0) | 12.0 |
| Course C | 2 | B+ (3.5) | 7.0 |
The result is (13.5 + 12.0 + 7.0) ÷ 8 = 4.06 / 4.5.
Important Conversion Limitation
The calculator compares the letter-grade point tables used by each scale. It does not issue an official credential evaluation. For an application, follow the receiving university's instructions and submit the GPA and maximum scale exactly as shown on your official transcript unless the institution requests another method.
Frequently Asked Questions
Is a 4.5 Korean GPA the same as a US 4.0 GPA?
No. The maximum values and letter-grade rules differ. Do not present a simple proportional conversion as an official US GPA unless the receiving institution explicitly allows it.
Are Pass and Non-Pass courses included?
Pass/Non-Pass courses are normally excluded from the grade-point average, although earned credits may still appear on a transcript. Check your university's rules.
Should I report 4.5 or 4.3?
Use the grading scale stated on your official transcript. If an application asks for the maximum possible GPA, enter that maximum alongside your result.
Practical GPA Tips
- Retake Courses: If your school allows, retaking grades below C+ can significantly boost your GPA.
- Check Credit Weights: Major courses often have higher credit weight than electives.
- Consistent Trend: An upward trend in grades over the years is viewed positively by admissions officers.
