The 9.5 conversion rule
Many boards, including CBSE, relate percentage and CGPA with a factor of 9.5. To turn a CGPA into an approximate percentage you multiply by 9.5; to go the other way you divide the percentage by 9.5. This tool does both directions.
How to convert
Pick a direction, enter your number, and read the result: CGPA = percentage ÷ 9.5 or
percentage = CGPA × 9.5. The 9.5 factor is an approximation used for indicative
conversions, so always check your board's official method for anything formal.
