Free calculators for colleges and students

CampusHub publishes free calculators for the arithmetic that recurs in higher education: converting SGPA and CGPA between scales and to percentage, working out credit hours from contact hours, and estimating programme-wise annual fees.

Conversion formulae differ between universities. Every tool states the formula it uses so you can check it against your own regulations before relying on the answer.

CGPA-to-percentage is the clearest example of why the formula matters more than the answer. Some universities multiply by 9.5, some by 10, some subtract a constant — and a student quoting the wrong one on an application has a problem nobody catches until it matters.

Why the conversion formula is printed

There is no single national rule for converting a CGPA to a percentage. Your university’s regulations specify one, and it is the only one that counts on a transcript or an application form.

These tools default to the most common convention, state it plainly, and let you substitute your own. A calculator that hides its formula is worse than doing the arithmetic by hand, because you cannot tell when it is wrong.

FAQ

Questions people ask

Phrased the way they arrive, answered so each one stands on its own.

How do I convert CGPA to percentage?

It depends on your university’s regulations. A common convention multiplies CGPA by 9.5, but others multiply by 10 or apply a subtraction. Check your own regulations — the number on a transcript has to match the rule your institution publishes.

Are these tools free?
