Frequently asked questions

How do I convert CGPA to percentage?
It depends on your university. Many use CGPA × 10; VTU and AKTU are commonly cited as (CGPA − 0.75) × 10; GTU as (CGPA − 0.5) × 10. Pick the formula, enter your CGPA, and the percentage updates as you type. Always confirm the rule on your university's circular.
Is 9.5 the right multiplier?
Only for old CBSE Class X grades. CBSE stopped issuing CGPA after 2017–18 and its ×9.5 was for school grades, so don't use it for a university CGPA unless your university says to. It stays here as a preset.
How do I convert a percentage back to CGPA?
Switch to "% → CGPA". The calculator reverses the chosen formula, and warns when your percentage is below or above what the formula can produce.
My university uses a different formula. Can I enter it?
Yes. Choose "My own formula" and type the multiplier and offset (percentage = a × CGPA + b). We can't promise to match every university, so use the rule your institution publishes.
Can I work out my CGPA from semester results?
Yes. Open "From semesters", enter each semester's SGPA and credits, and you get the credit-weighted CGPA, which you can then convert. If your university averages SGPAs without credits, give every semester the same credits.
Does it work for a 5 or 4 point scale?
Yes. Choose the scale; the proportional formula (CGPA ÷ scale × 100) and your own formula work on any scale. The named university formulas are for the 10-point scale only.
How accurate is the 4.0-scale GPA?
It is a straight proportion of your CGPA to 4.0, so only an estimate. US evaluation services such as WES use their own tables; there is no official conversion.
Is my data stored or uploaded anywhere?
No. Everything runs in your browser. Your last inputs are saved only in this browser's local storage. A copied link carries your numbers in the part after the #, which is never sent to a server.
Is it free, and do I need an account?
It is free, with no sign-up, no watermark and nothing to install.
