Formula & methodology

Formula used

CBSE (10-point scale)

percentage = CGPA x 9.5

The CBSE's own published conversion. The 9.5 multiplier comes from the average of the mid-points of CBSE's grade bands.

Origin: Central Board of Secondary Education.

VTU and SPPU

percentage = (CGPA - 0.75) x 10

Subtracts a fixed 0.75 before scaling, so it returns a lower percentage than a plain x10 at every point on the scale.

Anna University

percentage = CGPA x 10

A direct decimal shift of the 10-point CGPA.

Mumbai University

percentage = (CGPA x 7.1) + 11

A linear conversion with both a different slope and an offset, which is why it diverges sharply from the others at the ends of the scale.

Variable definitions

Step-by-step calculation

1.
This is the whole calculation. These formulas are not interchangeable and not approximations of one another — each university publishes its own, and they give materially different answers. A CGPA of 8.0 is 76% under CBSE, 72.5% under VTU and 67.8% under Mumbai University. Selecting the wrong one produces a number your institution will not recognise.
2.
Each formula is applied in reverse to convert a percentage back to a CGPA, using the same constants. Round-tripping a value returns the original figure, subject to rounding at two decimal places.

Common mistakes

Using the CBSE x9.5 formula for a university degree.
The x9.5 rule is a CBSE school-board formula. Applying it to an engineering or degree CGPA overstates the percentage at almost every point on the scale.
Treating the converted percentage as an official mark.
The authoritative figure is whatever appears on your transcript or conversion certificate. Use this to plan; use the certificate to apply.

Limitations

Only institutions whose conversion formula is publicly published are listed. If yours is not here, ask your examination office — do not substitute another institution's formula.
Some universities publish a conversion table with band-by-band values rather than a single linear formula, and a table will not always agree with a formula at every point.
Institutions revise conversion rules. Check your institution's current regulations before relying on a figure for an application.
Many employers and foreign universities apply their own conversion, which may differ from your institution's.

This page is educational. It applies a standard grading formula to the figures you enter and shows the arithmetic behind the result. The weighting, rounding and grade-point scale it uses are the common ones described above, but each school, college and examination board sets its own, so the figure here is a planning estimate rather than your official record. Check your institution's published grading policy before acting on it.

Conversion formulas are set by each university and can differ between regulations, batches and degree programmes. Where a transcript or an official conversion certificate exists, that document is what an employer or admissions office will accept — treat this calculator as a fast check, not as a substitute for it.

Help & FAQs

Frequently Asked Questions

Clear answers to common questions to help you use this calculator confidently.

How do I convert CGPA to percentage?

Tap to view the answer

Select your university or board from the dropdown, choose 'CGPA → Percentage', and enter your CGPA. The calculator applies your institution's specific formula — e.g., CBSE uses CGPA × 9.5, VTU uses (CGPA − 0.75) × 10, and Anna University uses CGPA × 10.

What is the CBSE CGPA to percentage formula?

Tap to view the answer

CBSE (Central Board of Secondary Education) uses: Percentage = CGPA × 9.5. So a CGPA of 8.5 converts to 80.75%, and a perfect 10 CGPA converts to 95%. This is the official formula printed on CBSE mark sheets.

Can I convert percentage back to CGPA?

Tap to view the answer

Yes — select 'Percentage → CGPA' as the conversion direction. The calculator reverses the official formula. For CBSE: CGPA = Percentage ÷ 9.5. For VTU: CGPA = (Percentage ÷ 10) + 0.75.

What is the difference between SGPA and CGPA?

Tap to view the answer

SGPA (Semester Grade Point Average) covers a single semester, while CGPA (Cumulative Grade Point Average) is the average across all semesters. Most universities use the same conversion formula for both — just apply it to the value you have.

Which universities are supported?

Tap to view the answer

The calculator supports CBSE, VTU, Anna University, Mumbai University, SPPU (Pune), GTU, JNTU Hyderabad, MAKAUT (WBUT), and generic 10-point and 4.0 GPA scales.
