Convert your CGPA to percentage, US GPA, and letter grade with multiple formula options.
CGPA (Cumulative Grade Point Average) is widely used in Indian education systems on a 10-point scale. To compare with percentage-based systems or international GPAs, conversion is needed. The most common formula multiplies CGPA by 9.5 (CBSE standard), but Anna University uses ×10. Enter your CGPA below and choose a formula to see your equivalent percentage, letter grade, and US GPA.
| CGPA Range | Percentage | US GPA | Letter Grade |

Multiply your CGPA by 9.5 (the standard formula used by CBSE and most Indian institutions). For example, a CGPA of 8.0 equals 8 × 9.5 = 76%. Some universities like Anna University use CGPA × 10 instead.
The standard formula is: Percentage = CGPA × 9.5. This is widely used by CBSE in India. Anna University uses: Percentage = CGPA × 10. Some institutions use custom multipliers, so always verify with your university's official conversion method.
A common approximation is: US GPA = (CGPA / 10) × 4. So a CGPA of 8.0 on a 10-point scale roughly equals a 3.2 US GPA. However, this is an approximation — official credential evaluation services like WES use more nuanced methods.
On a 10-point scale, a CGPA of 7.0+ is generally considered good, 8.0+ is very good, and 9.0+ is excellent. For competitive postgraduate programmes or top employers, a CGPA of 8.0+ is often expected.
CGPA and GPA are related but not identical. CGPA is typically on a 10-point scale and represents your cumulative average across all semesters. US GPA is on a 4.0 scale. GPA may refer to a single semester, while CGPA always refers to the cumulative average.
