Frequently asked questions
What is the formula to convert CGPA to percentage?
The most common formula, used by CBSE, is Percentage = CGPA × 9.5. Other institutions use different multipliers, which is why this calculator lets you adjust it.
Does every university use the same multiplier?
No — engineering colleges, universities on a 4.0 or 10.0 scale, and different boards often use their own conversion factor. Check your institution's official grading policy and enter the correct multiplier above.
Is this the same for SGPA?
Yes — SGPA (semester-wise) and CGPA (cumulative) use the same conversion approach; just enter your SGPA value in place of CGPA.
