JNTUH CGPA to percentage formula
Percentage = (Final CGPA − 0.5) × 10. For example, a final CGPA of 8.00 converts to 75.00%.
The reverse is CGPA = (Percentage ÷ 10) + 0.5. JNTUH's regulation states the conversion for the final CGPA; it is not a blanket rule for converting an individual semester SGPA.
The cited R25 and revised R22 B.Tech regulations use the same final-CGPA conversion. This page intentionally covers both directions instead of creating a near-duplicate percentage-to-CGPA page.
