About the SGPA, CGPA, and Percentage Tools

Why this tool exists

Grading systems can get complicated quickly, especially when you are balancing multiple semesters with different credit weights. We built this calculator so you do not have to manually multiply and divide points just to figure out where you stand academically. It handles the heavy lifting so you get an accurate view of your academic performance in seconds.

When should you use this tool?

How the tool works

The SGPA to CGPA calculator uses a standard weighted average formula. You simply enter your SGPA and the total credits for each semester. The tool multiplies those two numbers together for every semester, adds them all up, and then divides by your total accumulated credits. For the percentage conversion, you select your university's specific mathematical formula, and it applies the calculation directly to your CGPA.

Limitations and Accuracy

This calculator relies on standard mathematical formulas for calculating weighted and unweighted averages. However, keep in mind that every university has its own rules for rounding decimals and applying specific conversion multipliers. While this tool provides a highly reliable estimate, you should always verify your final numbers against your official university transcripts before submitting them for formal applications or background checks.

Frequently Asked Questions

Do I need to enter credits for the calculation to work?

If all your semesters carry the exact same number of credits, you can skip entering them and safely use the "Unweighted" calculation mode. However, if your credit load changes from one semester to the next, you must enter the credits and use the "Weighted" mode for an accurate result.

Which percentage formula should I choose?

The 9.5 multiplier is the standard default for CBSE and many general degree programs. If you are an engineering student, review your university's specific guidelines. Many technical universities use a deduction formula, such as multiplying by 10 only after subtracting 0.75 from your total CGPA.

Can I use this calculator if I have an active backlog?

Yes, but you have two options. You can either exclude that subject's credits and calculate your average based only on the subjects you have cleared, or you can wait and recalculate based on your updated marksheet once the backlog is officially cleared by your university.
