Understanding the Conversion
Marks to GPA conversion transforms raw marks or scores to the 4.0 GPA scale. This is essential because marks systems vary globally—some use out of 100, others 50, 80, 200, etc. GPA standardizes across systems.
Common mark scales: Out of 100 (most common), out of 50 (some schools), out of 80 (certain exams), out of 200 (some Indian systems). The conversion adapts to any maximum marks you specify.
Why conversion matters: International universities, employers, and scholarship programs need standardized GPA to evaluate students fairly across different systems.
Conversion Formulae
Marks to 4.0 GPA
GPA = (Marks Obtained ÷ Max Marks) × 4
Example: (85÷100)×4 = 3.4 GPA | (42.5÷50)×4 = 3.4 GPA
4.0 GPA to Marks
Marks = (GPA ÷ 4) × Max Marks
Example: (3.4÷4)×100 = 85 | (3.4÷4)×50 = 42.5
