Launch SGPA to CGPA CalculatorHow to Calculate SGPA at REC
4-step calculation process according to official REC examination regulations:
List Registered Credits
Check your REC syllabus to note credit hours (Cᵢ) for every registered theory course, laboratory, and elective.
Identify Grade Points
Convert your earned marks (0–100) or letter grades (O, S, A) into REC grade points (Gᵢ).
Multiply Quality Points
Multiply credits by earned grade points for each subject to obtain Quality Points: Qᵢ = Cᵢ × Gᵢ.
Divide by Total Credits
Sum all quality points and divide by total semester credits: SGPA = Σ(Cᵢ × Gᵢ) / Σ(Cᵢ).

REC SGPA Formula
Under Raghu Engineering College (REC Autonomous / JNTUK) examination ordinances, Semester Grade Point Average is calculated using credit-weighted summation:
Σ Cᵢ
Where Cᵢ = Course Credits, Gᵢ = Grade Points earned in subject i
Assigned credit weight based on weekly lecture, tutorial, and laboratory practical hours as specified in the REC scheme syllabus.
Numerical score mapped to your letter grade on the official 10-point scale (O=10, S=9, A=8, B=7).
The product of credits and grade points. Summing all quality points and dividing by total registered semester credits yields your official SGPA.

REC SGPA Calculator by Grades
Compute your term SGPA directly using official letter grades (O, S, A, B, C):
When semester grade cards are released by Raghu Engineering College (REC Autonomous / JNTUK), only letter grades are shown for each registered course. Using Mode 1 in our calculator above, select your earned letter grades for each theory and practical subject. The calculator automatically fetches the corresponding REC numerical point, weights it by credit hours, and generates your exact SGPA.
REC SGPA Calculator by Marks
