CGPA to Percentage Calculator
Enter your CGPA on the ten-point scale and press Calculate to get the percentage equivalent. For example, 8 CGPA in percentage is 76% under the 9.5 rule, get the percentage equivalent using the widely used × 9.5 convention.
About the CGPA to Percentage Calculator
There is no single national CGPA to percentage formula. The most common convention on a ten-point scale is percentage = CGPA × 9.5, popularised by several Indian universities and repeated in most online converters. It is a convention, not a law: VTU and AKTU subtract 0.75 before multiplying by 10, Anna University subtracts 0.5, and Mumbai University uses a linear fit of its own.
That matters because the answers differ. A CGPA of 8.0 becomes 76% with the 9.5 rule, 72.5% under the VTU and AKTU formulas, and 75% under Anna University's. When a form asks for a percentage, use the formula printed on your own transcript rather than a generic converter — including this one.
How the calculation works
- 10-point scale, common convention: percentage = CGPA × 9.5
- VTU / AKTU: percentage = (CGPA − 0.75) × 10
- Anna University: percentage = (CGPA − 0.5) × 10
- 4-point scale: percentage = CGPA ÷ 4 × 100
Reference values
| CGPA (10-point) | Percentage at × 9.5 |
|---|---|
| 6.0 | 57.0% |
| 6.5 | 61.75% |
| 7.0 | 66.5% |
| 7.5 | 71.25% |
| 8.0 | 76.0% |
| 8.5 | 80.75% |
| 9.0 | 85.5% |

Worked examples
- 6.0 = 57.0%.
- 6.5 = 61.75%.
- 7.0 = 66.5%.
- 7.5 = 71.25%.
- 8.0 = 76.0%.
Checking the answer
Check one row of the CGPA (10-point) chart by hand. A difference of a whole step (10 or 100) means a decimal point moved; a difference in the last digit is just rounding. The first row, 6.0 to 57.0%, is the one worth memorising because it anchors every other figure in the table.
Common mistakes
- Using a rounded factor for a large quantity, where the error multiplies.
- Rounding at the start of a calculation rather than at the end.
- Assuming two similarly named units are the same size.
Using this conversion
CGPA (10-point) and Percentage at × 9.5 do not share a single multiplier, so the chart is the reference rather than the arithmetic. Reading the nearest row and adjusting from it is faster and less error-prone than rebuilding the formula each time, especially on a phone at a counter or a site office.
When precision matters
Where a CGPA (10-point) figure is used for a specification or a payment, take the value from the converter rather than from a rounded Percentage at × 9.5 row, and note which convention was used so the other party can check it the same way.
A last check on the CGPA (10-point) table: 6.0 57.0% sits at the base of the chart, and the rows above it step in the same proportion, so you can scale from that first row instead of reading every line. If a figure you were quoted falls between two rows, it is the Percentage at × 9.5 side that has been rounded, not the conversion itself.
