How Calcutta University CGPA converts to percentage
The official formula
University of Calcutta Notification CSR/143/2024 (24 Dec 2024): CGPA × 10 = Percentage of marks (UG under CCF). Applicable to UG courses of studies under CCF per CSR/143/2024. Older CBCS cohorts should confirm whether the same notification applies to their marksheet.
For example, a Calcutta University CGPA of 7.8 converts to 78.00%.
Why university-specific pages matter
Calcutta University is one of India's larger affiliating universities — its conversion shape is not interchangeable with CBSE's ×9.5 or a plain ×10. This page locks the calculator to Calcutta University's published rule so you don't accidentally apply a neighbouring university's formula.
Other universities use a different formula
CGPA-to-percentage conversion is not standardised across India — each university publishes its own circular. The table below shows every formula this calculator supports, so you can double-check or switch if you need a different one.
Frequently asked questions
What is the Calcutta University CGPA to percentage formula?
University of Calcutta Notification CSR/143/2024 (24 Dec 2024): CGPA × 10 = Percentage of marks (UG under CCF). Applicable to UG courses of studies under CCF per CSR/143/2024. Older CBCS cohorts should confirm whether the same notification applies to their marksheet.
Is this the official Calcutta University formula?
Yes — it's taken from Calcutta University's own published circular/regulations, not estimated from a generic multiplier. Using the wrong formula (for example, assuming a flat ×9.5 multiplier when your university uses an offset) can misstate your percentage by several points on official documents.
Does the same formula apply to both CGPA and SGPA?
Yes for Calcutta University — the conversion is linear on the grade-point value itself. Use this page for a single semester's SGPA, or the companion CGPA page for your cumulative score.
How do I convert percentage back to grade points?
Switch to "Percentage → CGPA" mode above — it reverses the same Calcutta University formula correctly, including undoing any offset.
Can I use this for other universities too?
Yes — use the "University / board" dropdown in the calculator to switch to another supported university, or enter your own custom multiplier if yours is not listed.
