📊 CGPA to Percentage

Standard Formula: Percentage = CGPA × Conversion Factor

Common Factors:

  • 10.0 Scale: × 9.5 (India Standard)
  • 4.0 Scale: × 25 (US Standard)
  • Anna University: × 10
  • VTU: (CGPA - 0.75) × 10

🔄 Percentage to CGPA

Standard Formula: CGPA = Percentage ÷ Conversion Factor

Common Factors:

  • India Standard: ÷ 9.5
  • US Standard: ÷ 25
  • UK Standard: ÷ 20
  • Custom formulas vary by university

📈 SGPA to CGPA

Formula: CGPA = Σ(SGPA × Credits) ÷ Total Credits

Simplified: Average of all SGPAs

Weighted: Consider credit hours for accuracy

🎯 SGPA to Percentage

Two Methods:

  1. Convert SGPA to CGPA first, then to percentage

Frequently Asked Questions

What is the difference between CGPA and SGPA?

SGPA (Semester Grade Point Average) is the grade point average for a single semester, while CGPA (Cumulative Grade Point Average) is the overall average across all semesters. CGPA is calculated as the weighted average of all SGPAs, typically considering credit hours.

How accurate is this CGPA calculator?

Our calculator provides 99.9% accuracy using verified academic formulas and university-specific conversion standards. All calculations are cross-verified against educational institution guidelines and academic standards. The tool undergoes regular updates to maintain precision.

Can I use this for international university applications?

Yes! This calculator supports multiple international grading systems including US (4.0), UK, Canadian, Australian, and Indian scales. It includes university-specific formulas for accurate international grade conversions. However, for official applications, always verify with the specific institution.

Are conversion formulas the same for all universities?

No, conversion formulas vary significantly between universities and countries. Some use simple multiplication (×9.5, ×10), others use formulas like (CGPA-0.75)×10, and some have completely unique methods. Always check your university's official conversion policy for accurate results.
