Why do universities use different CGPA to percentage formulas?

Each university sets its own rule in its regulations or by notification. Some multiply by 10 (KTU, IPU, RGPV, Thapar), some subtract a constant first (AKTU − 0.75, GTU/CUSAT/DBATU/BPUT − 0.5), some use another multiplier (NIT Kurukshetra × 9, CBSE × 9.5) and HEC uses a band table.

Where do the formulas on these pages come from?

From each university's official regulation, ordinance, notification or certificate, linked on every page with the clause number. Where only an archived or college-hosted copy was available, the page says so.

Is SGPA the same as GPA?

Both are the credit-weighted average of grade points for one semester. Some universities (CUSAT, NIT Trichy, University of Madras, HEC Pakistan, NUC Nigeria) call it GPA; others call it SGPA.

My university is not listed. Can I still calculate my CGPA?

Yes — use the general SGPA to CGPA calculator, which weights semesters by credits. We only add a university page when we can cite its official rule.

University CGPA, SGPA & Percentage Calculators

A CGPA of 8.0 is not the same percentage everywhere. Under a plain CGPA × 10 rule, as at KTU or IPU, it is 80%; at AKTU the ordinance subtracts 0.75 first and gives 72.5%; NIT Kurukshetra multiplies by 9 for 72%; CBSE Class X uses 9.5 for 76%; and Pakistan's HEC does not multiply at all but reads the percentage from a band table. Grade points differ just as much — KTU and Amrita use half-point grades, BPUT gives a failed course 2 points, and Calcutta University's CCF scheme turns every mark into a decimal grade point.

Every calculator in this section is built from one university's own regulation, ordinance or notification, and each page cites the document, the clause and the link we checked. Where we could not find an official rule — for example a percentage conversion for SPPU engineering, Osmania or Amrita — the page says so and does not invent one.

Each university page has an SGPA calculator, a CGPA calculator that weights semesters by their credits, the official grade table in plain HTML, a worked example and the classification bands. Where the university publishes a conversion, a separate page converts CGPA to percentage and works backwards from a percentage cut-off to the CGPA you need.
