Quick Answer & Key Takeaway (TL;DR)

For CBSE 10th and 12th standards, the official formula to convert CGPA to percentage is: Percentage = CGPA × 9.5. For instance, an 8.4 CGPA equals 8.4 × 9.5 = 79.8%. Engineering universities (AICTE, Mumbai, VTU) use university-specific conversion formulas (often (CGPA - 0.75) × 10 or (CGPA - 0.5) × 10).

Most universities, scholarship applications, and job portals require candidates to submit marks as a percentage rather than a grade point average. A reliable percentage calculator from cgpa ensures your academic transcripts are correctly translated.

Percentage = CGPA × 9.5

If your overall CGPA is 8.6: 8.6 × 9.5 = 81.7%.

University & Engineering Formulas

Different universities employ distinct conversion equations:

  • AICTE Standard: Percentage = (CGPA - 0.75) × 10 (An 8.0 CGPA → 72.5%).
  • VTU (Visvesvaraya Tech): Percentage = (CGPA - 0.75) × 10.
  • Mumbai University: Percentage = 7.1 × CGPA + 11 (for CGPA ≥ 7).
