GPA Scale Converter
How to Use the GPA Scale Converter
In the Convert tab, enter your GPA on any scale, select the source scale (4.0, 4.33, 5.0, 10.0, or percentage), and choose your target scale. The calculator converts instantly and also shows all other scale equivalents at the bottom. Use the All Scales tab to see your GPA expressed on every scale simultaneously — ideal when you need to fill out international applications.
GPA Scale Conversion Method
Step 2: Convert = Normalized × Target Scale Maximum
Example: 3.5 on 4.0 scale → 10.0 scale
Normalized = 3.5 ÷ 4.0 = 0.875
Result = 0.875 × 10.0 = 8.75
This proportional method is the most universal approach. It assumes the same relative academic standing across all scales — a 3.5/4.0 GPA (87.5th percentile of maximum) converts to 87.5% of any other scale's maximum.
GPA Scale Reference
4.0 Scale (US standard): Most common in US colleges and universities. A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0.0
4.33 Scale (US+): Used by some US schools that award A+ = 4.3. Slightly more granular at the top.
5.0 Scale: Used by some US high schools for weighted GPAs (AP/honors classes get +1 point). Also used in some international systems.
10.0 Scale (India): Standard in IITs, NITs, and most Indian universities using the CGPA system. O (Outstanding) = 10, A+ = 9, A = 8, B+ = 7, B = 6.
Percentage (%): Used in many countries as the primary grading metric. Commonly used in India (alongside CGPA), South Asia, Middle East, and Africa.
