How JNTUH CGPA converts to percentage

Each block explains one part of how this works and how to read the result.

The official formula
JNTUH B.Tech Academic Regulations (R22 §11.2 / R25 §19.1): Percentage = (Final CGPA − 0.5) × 10. Applicable to B.Tech (and matching pharmacy/BBA regulations that publish the same clause) under JNTUH R22 and R25 schemes.
For example, a JNTUH CGPA of 8.4 converts to 79.00%.
What makes JNTUH's conversion distinctive
JNTUH B.Tech Academic Regulations (R22 §11.2 / R25 §19.1) use Percentage = (Final CGPA − 0.5) × 10 — a half-point offset that is not interchangeable with sister JNTU Kakinada’s R16 (CGPA − 0.75) × 10 rule.
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.
