How JNTUK CGPA converts to percentage

The official formula

JNTUK B.Tech (R16) Academic Regulations / conversion certificate: Percentage = (CGPA − 0.75) × 10 (2016-17 admitted batch onwards; lateral entry 2017-18+). Pre-R16 schemes may differ.. Applicable to JNTUK B.Tech under R16 academic regulations (and matching conversion certificates). Confirm older R10/R13 batches separately.

For example, a JNTUK CGPA of 8 converts to 72.50%.

Why university-specific pages matter

JNTUK 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 JNTUK'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 JNTUK CGPA to percentage formula?

Is this the official JNTUK formula?

Yes — it's taken from JNTUK'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 JNTUK — 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 JNTUK 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.
