CGPA to percentage converter

There is no single CGPA to percentage formula: CBSE class 10 used CGPA × 9.5, AICTE and VTU use (CGPA − 0.75) × 10, and many universities simply multiply by 10. The converter below shows all three for your CGPA, but the only correct figure for a form is the one from the formula printed on your own marksheet or issued by your university.

Worked example: CGPA 8.2

  1. 1CBSE class 10 (old CGPA scheme): 8.2 × 9.5 = 77.9%.
  2. 2AICTE / VTU: (8.2 − 0.75) × 10 = 7.45 × 10 = 74.5%.
  3. 3Simple multiply-by-10 universities: 8.2 × 10 = 82%.

The same 8.2 CGPA becomes 77.9%, 74.5% or 82% depending on the formula, so quote the one your board or university specifies.

Why does CBSE multiply CGPA by 9.5?

Under the old CBSE class 10 grading scheme, the board stated that an indicative percentage could be found by multiplying CGPA by 9.5. The factor came from comparing the average marks of students in each grade band with their grade points across several years of results. It applies to CBSE class 10 marksheets issued under that CGPA scheme, not to college CGPAs or to current CBSE results, which report marks directly.

What is the AICTE and VTU formula?

AICTE and VTU publish percentage = (CGPA − 0.75) × 10 for the 10-point scale. A CGPA of 7.75 becomes 70%, and 9.0 becomes 82.5%. Other technical universities have similar subtraction-based formulas with different constants. If your marksheet or transcript states a formula, use it exactly; employers and foreign universities usually check it against the document you submit. If your university has no published formula, say so on the form and give the CGPA itself.

Which formula should I use on a job or admission form?

  • First choice: the formula printed on your marksheet, transcript or university website.
  • If the form asks for a specific method, follow the form.
  • If your university issues a conversion certificate, attach it rather than converting yourself.
  • Do not pick the formula that gives the highest number; mismatches can be flagged during document checks.
  • Write the CGPA and the method used, for example 8.2 CGPA = 74.5% (AICTE formula), if the form has space.

CGPA to percentage: questions and answers

Is CGPA × 9.5 valid for college or university CGPA?

Not by default. The 9.5 factor was defined by CBSE for its class 10 CGPA scheme. Some colleges have adopted it, but many use × 10 or (CGPA − 0.75) × 10 instead. Check your institution's rule on the marksheet or the examination section of the university website.

How do I convert percentage back to CGPA?

Reverse the formula your institution uses. For × 9.5, divide the percentage by 9.5; for (CGPA − 0.75) × 10, divide by 10 and add 0.75; for × 10, divide by 10. So 74.5% becomes 7.45 + 0.75 = 8.2 under the AICTE formula.

Can I convert CGPA to a US GPA?

Not by a fixed formula that admissions offices accept. US universities usually ask for an evaluation from a credential service such as WES or ECE, or do it themselves. For a rough planning figure use the Indian percentage to US GPA converter in the related links, and treat the result as indicative only.

Why does the converter show three answers?

Because different boards and universities genuinely use different formulas, and showing one number could mislead you. Seeing them side by side makes it clear which one you are quoting. Pick the one that matches your board or university and note the method if the form has space for it.
