How JNTUK SGPA converts to percentage
Each block explains one part of how this works and how to read the result.
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 SGPA of 8 converts to 72.50%.
What makes JNTUK's conversion distinctive
JNTUK R16 conversion certificates use Percentage = (CGPA − 0.75) × 10 for 2016–17 admitted batches (lateral entry 2017–18+), matching VTU/AKTU’s shape rather than JNTUH’s −0.5 offset.
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 SGPA to percentage 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.
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 published conversion is the same linear function of the grade-point value for a semester SGPA or a cumulative CGPA ((SGPA − 0.75) × 10). Use this page for SGPA or the companion CGPA page for the cumulative score.
How do I convert percentage back to grade points?
Switch to "Percentage → SGPA" 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.
