CGPA SGPA & Percentage Calculator von Bikash Kumar

Doing CGPA to Percentage conversion in your head every time a result comes out gets old fast. This extension fixes that, two clicks and you have your answer, right from your browser toolbar.
It handles the three conversions students actually search for: CGPA to Percentage, SGPA to Percentage, and SGPA to CGPA across multiple semesters.
How it works:

Pick your conversion type from the dropdown
Enter your number and the result shows up instantly, no separate "calculate" button needed
Adding semesters is one click if you're averaging multiple SGPAs into a CGPA
Copy your result with a single tap so you're not retyping it anywhere

Say you just got your 6th semester SGPA and want your running CGPA without averaging five numbers by hand. Open the extension, type in each semester's SGPA, and it averages them for you on the spot.
This extension uses the standard 9.5 multiplier, the formula most universities follow. If your college uses a different scale, like VTU, Anna University, or Mumbai University, the popup links straight to the matching calculator on Cutoff Calculator so you get the exact number for your university.
