Percentage ↔ CGPA Converter

Education Calculators

Convert between percentage and CGPA using the CBSE multiplier or your own institution's formula.

This converter is intended for institutions that officially define a Percentage ↔ CGPA conversion. School students: the default uses the CBSE Class 10 (9.5×) conversion. College and university students (undergraduate or postgraduate): many institutions use a different multiplier, a different formula, or no official conversion at all. If your institution publishes its own conversion rule, choose Institution-Specific Multiplier and enter the value specified by your institution.

CGPA

CBSE Class 10 uses the official 9.5× multiplier. For other boards, check your institution's guidelines.

7.5 CGPA → 71.25%7.5 × 9.5 = 71.25 — not 75%

Frequently Asked Questions

No — under the standard CBSE formula, 7.5 CGPA converts to 71.25% (7.5 × 9.5), not 75%. The multiplier is 9.5, not 10, so CGPA and percentage only line up exactly at the very top of the scale (10 CGPA = 100%).

Common Mistakes to Avoid

  • The CBSE multiplier is 9.5, not 10 — a 7.5 CGPA is 71.25%, not 75%. It's a common assumption that CGPA × 10 gives your percentage. The official CBSE Class 10 formula uses 9.5 as the multiplier, so the two only match up at CGPA = 10 (which gives exactly 100%). Anywhere else, using 10 instead of 9.5 overstates your percentage.
  • CBSE's 9.5 multiplier doesn't apply to your university's CGPA. CBSE has no jurisdiction over college or university-level CGPA. Many universities publish their own multiplier, use an entirely different formula, or have no official conversion at all — check your institution's own rule and use Institution-Specific Multiplier if it differs from 9.5.
