For credential evaluations (such as WES for graduate school applications), individual course marks are mapped to local percentile curves rather than straight arithmetic division.

Converting Percentage Marks into GPA Scales

Converting academic percentages into GPA scales requires understanding whether your receiving institution uses a discrete letter-grade mapping (standard in the United States) or a continuous linear formula (common in European and international programs).

Frequently Asked Questions

On the standard US 4.0 scale: 93–100% corresponds to 4.0 (A), 90–92% is 3.7 (A-), 87–89% is 3.3 (B+), 83–86% is 3.0 (B), 80–82% is 2.7 (B-), 77–79% is 2.3 (C+), 73–76% is 2.0 (C), 70–72% is 1.7 (C-), 67–69% is 1.3 (D+), 65–66% is 1.0 (D), and below 65% is 0.0 (F).
How do Indian CBSE percentages convert to 10.0 CGPA?
The Central Board of Secondary Education (CBSE) officially calculates 10.0 CGPA using: CGPA = Percentage / 9.5. For example, an 85.5% aggregate converts to: 85.5 / 9.5 = 9.0 CGPA.
What is the German Bavarian Formula for percentage conversion?
German universities convert foreign grades using the modified Bavarian Formula: German Grade = 1 + 3 × [(N_max - N) / (N_max - N_min)], where N_max is 100%, N_min is passing percentage (e.g. 50%), and N is your actual score. In Germany, 1.0 is highest and 4.0 is minimum pass.
