GPA & CGPA Converter Guide: 4.0 GPA, 10.0 CGPA, and Percentage Conversion

Grade systems differ internationally. While United States institutions report academic performance on a 4.0 GPA scale, Indian boards and universities rely on a 10.0 CGPA or overall percentage. Converting between them is vital for WES evaluations and study-abroad applications.

GPA to Percentage Conversion (4.0 Scale)

For general conversions, standard linear mapping is applied to translate a 4.0 scale score to a 100% basis:

• Formula: $\text{Percentage} = \left(\frac{\text{GPA}}{4.0}\right) \times 100$
• Example: A GPA of 3.6 translates to $\left(\frac{3.6}{4.0}\right) \times 100 = 90\%$.

CGPA to Percentage Conversion (10-Point Scale)

For Indian institutions on a 10-point scale, the multiplier varies:

• CBSE: $\text{Percentage} = \text{CGPA} \times 9.5$
• VTU: $\text{Percentage} = (\text{CGPA} - 0.75) \times 10$
• Anna University: $\text{Percentage} = \text{CGPA} \times 10$
• Mumbai University:
  • For CGPA < 7: $\text{Percentage} = 7.25 \times \text{CGPA} + 11$
  • For CGPA ≥ 7: $\text{Percentage} = 7.1 \times \text{CGPA} + 12$

Percentage to GPA/CGPA Conversion

To reverse the calculations:

• To 4.0 GPA Scale: $\text{GPA} = \left(\frac{\text{Percentage}}{100}\right) \times 4.0$
• To CBSE CGPA: $\text{CGPA} = \frac{\text{Percentage}}{9.5}$
