Convert CGPA to percentage only with the formula your university actually published.

FormulaCGPA ships 10 audited official schemes and refuses to invent the rest. Every result shows the equation, circular or regulation, scheme year, valid range, worked arithmetic, and a caveat.

Verified institutions

A small accurate set is the product. Third-party calculators that apply one multiplier to every marksheet are listed on the methodology page as contrast, not as sources.

No silent 9.5

CBSE’s discontinued Class 10 rule is not a university conversion. It never auto-fills here.

Missing formula = said out loud

Anna University is included as a certificate-only case so the empty state is a feature, not a gap.

Quick answers

Is there one CGPA-to-percentage formula for all Indian universities?

No. There is no universal conversion. CBSE’s old Class 10 multiplier of 9.5 is a board rule, not a university rule, and FormulaCGPA never applies it silently.

What if my university is missing?

If we cannot quote an official circular or regulation, the institution is excluded or listed as “No official conversion published.” Use the labelled unofficial custom formula only as a working figure.

Can I convert percentage back to CGPA?

Only when the official formula is linear and reversible. The reverse equation is shown on the result. Mumbai’s rounding to the next integer means the reverse is approximate.
