CGPA to GPA Converter

This is the first thing to understand, because almost every conversion chart online presents one number as though it were authoritative. An 8.5 CGPA on a 10-point scale converts to 3.4 by proportion. Run the same 8.5 through the CBSE multiplying factor and you get 80.75%, and read that through US letter-grade bands and you land lower still. Same input, three defensible answers.

None of them is wrong. They answer slightly different questions, and institutions genuinely disagree about which to use — which is why this tool makes you choose the method instead of hiding the decision. If your target university or credential evaluator publishes a conversion, that figure beats anything computed here.

Where a form accepts your original scale, the safest submission is your unconverted CGPA with the maximum stated — for example 8.5/10 — plus the marksheet. An admissions office would generally rather run its own conversion than inherit yours.

Linear (proportional) divides by your scale maximum and multiplies by the destination maximum: CGPA / 10 x 4. It is transparent, reversible, and what most self-reporting application forms expect. Use it unless you have a reason not to.

Via percentage converts to a percentage first using a multiplying factor, then reads that percentage through the destination scale's letter bands. This mirrors how an Indian marksheet is normally interpreted, and it is the method behind most published conversion tables. Because it passes through letter bands, its output steps rather than scaling smoothly — two CGPAs a tenth apart can land on the same GPA.

The factor itself is a convention rather than a derivation. CBSE publishes x9.5; plenty of universities use a flat x10; VTU reaches a percentage with (CGPA - 0.75) x 10. Check what your institution publishes before putting a number on an official form.

Linear conversion, with the CBSE x9.5 percentage alongside for reference. Every row is generated by the same calculation the tool above runs.

The reverse direction comes up more often than people expect — a US transcript going to an Indian university, or a form that will only accept a 10-point figure. Use the swap button in the tool to flip the scales.

Nigerian universities and several Indian institutions grade out of 5. The arithmetic is identical — only the scale maximum changes, which is exactly why using the wrong maximum is the most common conversion mistake.

Using the wrong scale maximum. A 4.35 is excellent out of 5 and mediocre out of 10 — it converts to 8.7 on a 10-point scale, not 4.35. Check the maximum printed on your marksheet before anything else.

Converting an already-converted figure. If your university already prints a percentage, convert from that percentage — not from a CGPA you derived from it. Each conversion step adds rounding and method error.

Treating a converted GPA as official. It is an estimate. Credential evaluators assess course by course against country-specific scales, and their result can differ from any single-number formula.

Confusing SGPA with CGPA. SGPA covers one semester; CGPA is the running figure across all of them. To roll a semester into your cumulative record, use the cumulative GPA calculator instead.

This page translates a CGPA you already have onto a different scale. If you need to work out the CGPA itself from your subjects, credits and grade points — including its division or class band and its percentage equivalent — use the CGPA calculator, then bring the result back here to convert it.
