VTU SGPA to Percentage Calculator
VTU affiliates the majority of engineering colleges across Karnataka and uses a formula that is easy to get wrong if you assume a plain multiplier. Enter your SGPA below for an instant, correctly-converted percentage.
VTU official formula (vtu.ac.in): Percentage = (SGPA − 0.75) × 10
How VTU SGPA converts to percentage
The official formula
VTU official formula (vtu.ac.in): Percentage = (CGPA − 0.75) × 10. Applicable to the 2015, 2017, and 2018 schemes as published in VTU's official CGPA standard formula circular.
For example, a VTU SGPA of 8.6 converts to 78.50%.
Why university-specific pages matter
VTU 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 VTU'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 VTU SGPA to percentage formula?
VTU official formula (vtu.ac.in): Percentage = (CGPA − 0.75) × 10. Applicable to the 2015, 2017, and 2018 schemes as published in VTU's official CGPA standard formula circular.
Is this the official VTU formula?
Yes — it's taken from VTU'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 VTU — 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 → SGPA" mode above — it reverses the same VTU 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.
