JNTUH SGPA & CGPA Calculator
Grade points: O=10, A+=9, A=8, B+=7, B=6, C=5, F=0 (pass needs C/5+). Percentage = (CGPA − 0.5) × 10.
JNTUH CGPA to percentage — the official formula
Jawaharlal Nehru Technological University Hyderabad (JNTUH) uses a 10-point grading system, and its CGPA-to-percentage conversion is fixed in the academic regulations. The calculator above computes your SGPA from subject credits and grade points and converts a CGPA to percentage with the official JNTUH formula.
The JNTUH formula
This is specified in JNTUH B.Tech Academic Regulations (Clause 11.2) and applies uniformly across the R16, R18 and R22 regulations — the regulation year changes your credits and subjects, not the conversion. Example: a CGPA of 8.5 gives (8.5 − 0.5) × 10 = 80%. The reverse is CGPA = (Percentage ÷ 10) + 0.5.
How SGPA and CGPA are calculated
You must score grade point 5 (C) or above to pass a subject; an F (0) drags your SGPA until cleared.
