Students and exam applicants constantly need to convert between marks, percentage and CGPA — for application forms, eligibility checks and admissions. This tool does all three: calculate your percentage from marks obtained, convert a CGPA to a percentage, and convert a percentage back to CGPA.
The CBSE conversion uses a factor of 9.5 (Percentage = CGPA × 9.5), but you can change the multiplier if your board or university uses a different one. Everything runs in your browser, with nothing stored.
