How to Convert GPA Scales
Converting between GPA scales requires understanding the relationship between different systems:
4.0 to 5.0 Scale Conversion
Formula: (GPA / 4.0) × 5.0 = Converted GPA
Example: 3.5 on 4.0 scale → (3.5 / 4.0) × 5.0 = 4.375 on 5.0 scale
GPA to Percentage Conversion
Common formula: (GPA / 4.0) × 100 = Percentage
Example: 3.0 GPA → (3.0 / 4.0) × 100 = 75%
Percentage to GPA Conversion
Formula: (Percentage / 100) × 4.0 = GPA
Example: 85% → (85 / 100) × 4.0 = 3.4 GPA
