The JNTU CGPA to percentage formula
JNTU Hyderabad (JNTUH) does not use the common × 9.5 rule. Its official conversion, used under the R18 and R22 regulations, is:
Percentage = (CGPA − 0.75) × 10
The − 0.75 is the part students miss. Like VTU, JNTUH subtracts 0.75 before multiplying, so JNTU percentages come out a few points lower than the generic formula would suggest.
What is 8.0 CGPA in percentage in JNTU?
Plug it in: (8.0 − 0.75) × 10 = 7.25 × 10 = 72.5%. The generic × 9.5 rule would give 76% — a 3.5-point overstatement. Use the JNTUH formula for anything official.
