GPA Converter — Conversion Formulas, Job Application Tips & FAQ

The GPA Converter translates between South Korea's three common grading scales — 4.5, 4.3, and 100-point — used across Korean universities. Enter course names, credit hours, and grades to calculate your overall GPA and separate major vs. liberal arts GPAs, with instant conversion to all three scales. 【GPA Conversion Formulas】 4.5 → 4.3: GPA(4.3) = GPA(4.5) × (4.3 ÷ 4.5). For example, a 4.0 on the 4.5 scale equals approximately 3.82 on the 4.3 scale. The 100-point conversion uses grade midpoints: A+ ≈ 97.5, A ≈ 92.0, B+ ≈ 87.0, B ≈ 82.0, and so on. 【Tips for Job Applications】 When filling out Korean job application forms, always verify which GPA scale the company expects. Some large corporations assume 4.5 as the maximum, so submitting a 4.3-scale score could appear inflated or cause confusion. Many public enterprise (공기업) exams require a 100-point GPA, so convert your grade accurately beforehand.
