Converting Jawaharlal Nehru Technological University Gurajada, Vizianagaram (JNTU-GV) percentage back to CGPA
Jawaharlal Nehru Technological University Gurajada, Vizianagaram (JNTU-GV) (Andhra Pradesh) officially converts CGPA to percentage with cohort-keyed — R23: % = (CGPA − 0.5) × 10; R20, R19 and R16: % = (CGPA − 0.75) × 10.

Worked example
The official Jawaharlal Nehru Technological University Gurajada, Vizianagaram (JNTU-GV) formula is cohort-keyed — R23: % = (CGPA − 0.5) × 10; R20, R19 and R16: % = (CGPA − 0.75) × 10. Starting from a percentage of 75%, the formula reverses to a CGPA of about 8 on the 10-point scale. You can check this by running 8 through the forward Jawaharlal Nehru Technological University Gurajada, Vizianagaram (JNTU-GV) CGPA to percentage calculator — it returns 75%, confirming the two directions agree.
Why this is an estimate, not an official figure
A college issues your percentage from your actual CGPA, not the other way around — so reversing the formula recovers the CGPA that would produce that percentage. When both numbers appear on your grade card, always quote the official CGPA rather than this estimate.
Source & verification
own — R20 verified from JNTU-GV's Directorate of Academic Planning, Academic Regulations (R20) for B.Tech (Regular), §18(iv). R23 verified from the JNTU-GV B.Tech R23 regulation, §19 Award of Class. R19 read in full from JNTU-GV College of Engineering Vizianagaram and confirmed to contain no conversion clause; its constant derives from the JNTUK conversion certificate.
⚠️ THE CONSTANT CHANGED BETWEEN R20 AND R23. R20 and earlier subtract 0.75; R23 subtracts 0.5. At CGPA 8.0 that is 72.5% under R20 and 75% under R23. All four generations were live in 2025 examinations, so the regulation code on your hall ticket decides the answer. || THE GRADE LETTERS ALSO CHANGED. R19 uses O/S/A/B/C/D/F where O = 10, S = 9, A = 8. R20 uses A+/A/B/C/D/E/F where A+ = 10, A = 9, B = 8. AN 'A' IS 8 POINTS UNDER R19 AND 9 UNDER R20 — do not read one grade card against the other's table. || THE PASS FLOOR ROSE FROM 4.75 TO 5.00 between R19 and R20, and Distinction under both R19 and R20 requires no supplementary appearance in any subject regardless of final CGPA. || AUTONOMOUS COLLEGES SET THEIR OWN CONSTANT AND ROUGHLY A QUARTER DIFFER FROM THE UNIVERSITY. This entry applies to students at non-autonomous affiliated colleges, and to students at autonomous colleges admitted BEFORE that college received autonomy. Avanthi Institute of Engineering and Technology at Tamaram is JNTU-GV affiliated and autonomous and uses −0.75 under its own R24 — while its sister campus at Cherukupally uses −0.5.
