How college CGPA formulas actually work
Formulas are university-level, not college-level
Every affiliated college under VTU uses VTU's published conversion; every JNTUH-affiliated college uses JNTUH's (CGPA − 0.5) × 10 rule. Building thousands of near-identical per-college pages would duplicate content without adding accuracy — this single searchable tool resolves the affiliating university and runs the verified formula.
Our college list is curated from public AISHE / UGC / AICTE affiliation knowledge and well-known institutional records. It is not a complete national database; always cross-check your marksheet.
Search, confirm, convert
Type your college name or city in the typeahead. On select, we show the affiliating university, the readable formula, and the primary source citation from that university's circular — then embed the same CGPA calculator used across Knwdle's university pages, pre-set to that formula id.
If your college isn't listed
Use the general CGPA to Percentage Calculator and choose your university from the dropdown, or open a dedicated university page (VTU, Anna, Mumbai, DU, JNTUH, and others). If your university uses a custom multiplier printed on the marksheet, pick "Custom formula" there.
Frequently asked questions
Why is there one college search tool instead of a page per college?
CGPA-to-percentage formulas are set by the affiliating university, not by individual colleges. Thousands of colleges share a few hundred university formulas — building one thin page per college would duplicate content. This tool maps your college to the verified university formula instead.
Is every Indian college in this list?
No — the lookup currently covers 150 curated, well-known colleges. Affiliation mapping is curated from public AISHE / UGC / AICTE affiliation knowledge — not a complete national database. If your college is missing, use the all-universities CGPA calculator and select your affiliating university, or enter the multiplier printed on your marksheet.
Why does my college use a different formula from CBSE ×9.5?
×9.5 is CBSE and Delhi University's published rule. Most technological universities use a different shape: Anna and KTU use ×10, JNTUH/JNTUA/GTU use (CGPA − 0.5) × 10, and VTU/AKTU/MAKAUT use (CGPA − 0.75) × 10. Mumbai University uses (CGPA × 7.1) + 11. Applying CBSE's multiplier to a VTU or JNTUH score silently misstates your percentage.
What if my college is autonomous or deemed?
Autonomous and deemed institutions often publish their own conversion rule. If they appear in this list (e.g. VIT, SRM), we use their published formula. Otherwise check the reverse of your consolidated marksheet or the institution's examination regulations.
Can I convert percentage back to CGPA after selecting my college?
Yes — once a college is selected, the embedded calculator supports both directions. Switch to "Percentage → CGPA" mode to reverse the same university formula, including undoing any offset.
Can I call this from an API / AI agent?
Yes — GET /api/tools/college-cgpa-percentage-calculator?college=…&cgpa=… returns matching colleges and the converted percentage. See the developers section below.
