VTU CGPA to percentage

Select General (10-point) on CGPA to percentage — there is no separate VTU entry, because the formula is identical and adding a duplicate labelled with a university name would imply a verification that has not happened. The class column uses the common Indian boundaries, which your own regulations may set differently.

A straight ×10 assumes the grade scale and the percentage scale line up along their whole length. They do not: a pass grade is typically a 4 awarded for marks around 40, which a straight ×10 happens to get right, and the fit drifts upward everywhere above that because the bands are not evenly spaced.

Subtracting 0.75 first shifts the whole line down by 7.5 points, which brings the middle of the range closer to what marksheets actually show. It is a correction fitted to observed data rather than a derivation from first principles — which is exactly why it is a convention and why this site labels it as one. The formula page sets the four common rules side by side.

Because of that shift, a perfect 10.00 produces 92.50% rather than 100%. Nothing under this rule reaches the top of the percentage scale, and the inverse behaves accordingly — feed it 95% and it returns 10.25, which is off the scale. Percentage to CGPA refuses that case rather than printing it.

If a form demands a percentage above 92.50% and your grade card is a ten-point CGPA converted this way, the number cannot exist. That is a question for your examination section, not an arithmetic problem to solve harder.

VTU has run several schemes, referred to by admission year, and the grading and conversion rules are set per scheme. A formula correct for one batch is not automatically correct for another. Check, in order:

1. The regulations for your scheme and admission year.
2. A circular from the Registrar (Evaluation), which is what colleges are instructed to apply.
3. The reverse of your own grade card, where the grading key is often printed.
4. A written reply from your college examination section.

If you hold the issuing document, send it in. A formula with a source behind it is published here as verified, with the document linked and the date it was read. Without one it ships the way this one does.

Both are credit-weighted averages of grade points — SGPA for one semester, CGPA across every semester completed. The conversion formula applies to either, and the arithmetic underneath is the ordinary one: multiply each subject’s grade point by its credits, add, divide by total credits. The SGPA calculator and CGPA calculator do both levels with your own figures.
