SGPA to CGPA Converter

Spluxly’s free online SGPA to CGPA Converter is a flexible and accurate academic grade conversion tool designed for university and college students who need to calculate their Cumulative Grade Point Average from individual Semester Grade Point Averages. SGPA measures academic performance within a single semester, while CGPA provides a comprehensive picture of overall performance across all completed semesters — making CGPA the figure most commonly required for placements, higher education applications, and academic evaluations. The converter offers two calculation methods to match different institutional credit structures: Simple Average mode assumes equal credit weightage across all semesters and computes CGPA as a straightforward mean of all entered SGPAs, while Weighted Average mode accepts custom credit hours for each semester and computes a credit-weighted CGPA that more accurately reflects the academic load of each term. Enter your SGPA values for each semester, add or remove semesters as needed, and the calculator instantly returns your CGPA and its equivalent percentage using the standard conversion factor of 9.5. Completely free, no registration required.

How to Use the SGPA to CGPA Converter Online

Converting your SGPA values to a cumulative CGPA takes just seconds. Follow these simple steps:

• Choose Your Calculation Method – Select Simple Average if all your semesters carry equal credit weightage, or Weighted Average if your semesters have different credit totals; the credits input fields appear automatically when Weighted Average is selected
• Enter Semester 1 SGPA – Type your first semester’s SGPA (e.g., 8.75) into the Semester 1 input field; accepted values are 0.0 to 10.0
• Enter Semester 2 SGPA – Type your second semester’s SGPA (e.g., 9.00) into the Semester 2 input field
• Enter Credits (Weighted Average only) – If using Weighted Average mode, enter the credit hours for each semester (e.g., 20 for Semester 1, 18 for Semester 2)
• Click Add Semester – Add additional semester rows as needed for every completed term; each new row animates in and is numbered automatically
• Remove Semesters (if needed) – Click the X button on any semester row beyond the first two to remove it from the calculation
• Click Calculate CGPA – Instantly receive your CGPA result and equivalent percentage displayed in the result card with a smooth scroll to the output
• Review Your Results – See your CGPA (e.g., 8.88) and equivalent percentage (e.g., 84.31%) displayed clearly in the result panel

How SGPA to CGPA Conversion Works

CGPA is calculated from SGPA values using one of two methods depending on whether all semesters carry equal or different credit weightages.

Method 1 — Simple Average (Equal Credits): CGPA = Sum of All SGPAs ÷ Number of Semesters

Example for four semesters (SGPAs: 8.75, 9.00, 8.50, 9.25): CGPA = (8.75 + 9.00 + 8.50 + 9.25) ÷ 4 = 35.50 ÷ 4 = 8.88

Method 2 — Weighted Average (Custom Credits): CGPA = Σ (SGPA × Credits) ÷ Σ (Total Credits)

Example for two semesters (SGPAs: 8.75 and 9.00; Credits: 20 and 18): CGPA = (8.75 × 20 + 9.00 × 18) ÷ (20 + 18) CGPA = (175.0 + 162.0) ÷ 38 = 337.0 ÷ 38 = 8.87

Equivalent Percentage Conversion: Percentage = CGPA × 9.5

Example: CGPA 8.88 × 9.5 = 84.36%
