CGPA vs GPA

The mechanics match closely enough that people assume the numbers do too. They do not, and the reason is in the fourth row.

Divide a CGPA by 10 and multiply by 4 and an 8.00 becomes 3.20. That is the arithmetic and it is what CGPA to GPA computes. What it assumes is that the two scales measure in the same units along their whole length, and they do not.

An Indian 60% is a first class and a genuinely respectable result — it is above the cut-off most employers use. Convert it through the general formula and it is a CGPA of 6.75, which maps linearly to a GPA of 2.70. To a US admissions officer who has never read an Indian marksheet, 2.70 reads as weak. Nothing about the student changed; the scale did.

The distortion runs the other way at the top. Indian ordinances award a 10 for anything from 90 upwards, and 90 in an Indian engineering paper is uncommon. A US A grade starts at 90 too, but American course marks cluster much higher. So a 9.0 CGPA is rarer than the 3.60 GPA it maps to.

Read the last two columns together and the problem is visible. A 6.00 CGPA is 52.50% — a pass, and at some universities a second class. The same row says 2.40, which in the American reading is close to academic probation. Two very different verdicts on one student.

Because there is no document behind it. No Indian university publishes an official four-point equivalent of its own scale, so there is no ordinance, circular or examination manual to cite. Every formula on this site is labelled either verified against an issuing document — which is then linked with the date it was read — or not verified. This one can only ever be the second.

A verified badge without a citation is worse than no claim at all, because you would then trust it. That is why the conversion is offered with the label attached rather than quietly presented as fact.

Most programmes abroad do not want your arithmetic. They want the transcript with the grading key printed on it, and for many they want a credential evaluation from WES, ECE or the institution’s own office. Those services read the ordinance, the credit structure and the grading bands, which is exactly what a single multiplier throws away.

• Where a form has a free-text box, write the figure with its scale — “8.00 / 10” — which is accurate and cannot be misread.
• Where a numeric four-point field is mandatory, use the converted figure and state the derivation in any adjacent field.
• Where the application asks for a percentage rather than a GPA, convert on your university formula instead: CGPA to percentage shows the working.

In India, GPA is often used loosely to mean a single semester — what most universities call SGPA. In the United States it almost always means the cumulative figure for the whole degree. If someone asks for your GPA and you are unsure which they mean, the safe answer states both the period and the scale: “8.23 / 10 cumulative, across four semesters”.
