JNTUK SGPA to CGPA Calculator

Calculate your Jawaharlal Nehru Technological University Kakinada results with this SGPA to CGPA calculator JNTUK. It supports both equal-credit and weighted CGPA and explains every calculation.

How JNTUK grading works

JNTUK uses a 10-point scale tied to its academic regulations (R-series). SGPA is awarded each semester; CGPA aggregates across semesters. Credits per subject are defined in the curriculum; your semester grade card totals them. Because JNTUK semesters can carry different project/lab loads, the weighted formula – Σ(SGPA×credits)/Σcredits – gives the fairest CGPA. The calculator defaults to weighted when every row has credits and tells you it did so.

Worked example for JNTUK

Suppose Sem 6: 8.20 (22 credits), Sem 7: 7.70 (20 credits) → CGPA = (180.4 + 154.0)/42 = 334.4/42 = 7.96. Simple average = 7.95. The breakdown table shows SGPA, credits, SGPA×credits and running CGPA after each semester, so you see where an improvement lifted your cumulative score.

Percentage at JNTUK – the official rule

JNTUK's Academic Regulations R19 state the conversion directly: Equivalent Percentage = (CGPA − 0.75) × 10 (see the official R19 regulations on jntuk.edu.in ↗). So the worked example above, CGPA 7.96, converts to (7.96 − 0.75) × 10 = 72.10%. JNTUK updates its regulations across R-series years, so confirm that your batch's regulation carries the same clause — your regulation's Academic Regulations PDF and the footer of your grade card are the deciding documents, and the calculator links the official source with the result.

Common slip-ups

• Mixing 10-point SGPAs with an old percentage table from another university.
• Entering SGPA as 82 instead of 8.2.
• Ignoring that failed-lab re-registration may affect credit totals per JNTUK rules.
