About GradeCalc Tools

GradeCalc Tools is a small, free website that helps students convert grades quickly and correctly. Our calculators cover the conversions students search for most: CGPA to percentage, percentage to CGPA, SGPA to CGPA, and attendance planning.

How we work

• Every calculator shows the formula it uses, so you can check the maths yourself.
• Everything runs in your browser — we do not collect or store the numbers you enter.
• The site is free for everyone, with no accounts and no limits.

Important note

Conversion formulas are published by each university or board and can change. Our results are reliable estimates, but your institution's official figure is the final one. See our Disclaimer.
