I had read this generalised rule somewhere. But I am not sure. If I have 7.9 CGPA, multiply it by 9.5= 75.05% If I have 80%, CGPA= 80/9.5=8.42

CGPA is defined on all student's comparative performance. suppose in 100 mark paper highest mark secured by topper is 90 marks then. 90 marks will be 100% and if student x will get 80 marks then CGPA of student x will be: 100/90*80 = 88.89 . on scale of 10 its 8.9.

I found it on one of the CBSE sites,which validates both the points mentioned above: ----- Full Form of CGPA ? Cumulative Grade Point Average. What is CGPA ? It is an overall indicative percentage of marks. How to calculate percentage from CGPA ? Multiply the CGPA with 9.5 or use the above calculator to get the indicative percentage. Why multiply with 9.5 only ? The Board took the result of the last five years and calculated the average marks of all candidates who had scored between 91 and 100. That average turned out to be close to 95 marks. Since the equivalent Grade Point for the 91-100 band (A1 grade) of marks is 10, it then divided the average result of 95 by 10. The result is 9.5. -----

So, isn't there a standard rule for doing that? What formula does calculator apply? Or will it vary from institution to institution? Knowing this can help a lot to calculate it ourselves while applying to certain universities that specifically ask for CGPA instead of percentages.

To my Knowledge,it differs from univ to univ.Earlier when i needed i found one in internet and applied but later i got a formula from our Univ where the result differed.so its better to ask your Univ COE section for clear and clarifications if needed.

There is a program of standard deviation (statistics). It takes the marks of topper as reference 10 pointer. and the lower extreme is 45-50% in VNIT( Which this means 0 pointer). Depending on the lower and higher maximum, windows of 1, 2, 3...10 pointer is decided. The window is usually. of 4-5 marks If topper gets below lower extremum everyone fails. (This of course never happens but only a worst case possibility.)

Thanks for sharing that information. I am sure it will be useful for many students. I wish we could collect the data for this conversion in one place.

@Anoop Kumar Just wondering if this is correct method - 8.08 CGPA 8.08 / 10 = 0.808 0.808 * 100 = 80.8% 3.44/4 CGPA 3.44 / 4 = 0.86 0.86 * 100 = 86%

CGPA (cumulative grade point average) to percentage in BPUT (Biju Patnaik university of technology) where I studied: Percentage = (CGPA-0.50) * 100 It is available in BPUT website!

In VNIT cgpa is more of a grade. Although in some other Universities it is as stated by @Ankita Katdare and @Anoop Kumar . AA means 10 pointer, AB=9, BB=8, BC=7 and so on. The windows for CGPA are decided by individual professor's software. Although the one who secures top most marks (not necessarily 100% and may be much less eg. 56%) is most likely to be awarded 10 pointer. This type grading system is dependent on relative ranking irrespective of difficulty level of paper in each academic year.

That would be an incorrect use of the Grading system in Engineering at least . Also the CBSE system is pretty well defined for the objectives it has stated.

In RGPV University if someone got 8.2 CGPA on scale of 10 then for Percentage you have to simply multiply CGPA with 10. 8.2 * 10 = 82.0%

I guess the simplest method to calculate percentage for CBSE results is this: Subject wise Percentage = 9.5 x GP of the Subject. Overall Percentage = 9.5 x CGPA So, if you have 8 CGPA, percentage: 9.5 x 8 = 76% So, if you have 9 CGPA, percentage: 9.5 x 9 = 85.5% Here's a sample chart - CGPA 10 means 95% CGPA 9 means 85.5% CGPA 8 means 76% CGPA 7 means 66.5% CGPA 6 means 57% CGPA 5 means 47.5% CGPA 4 means 38% CGPA 3 means 28.5% CGPA 2 means 19% CGPA 1 means 9.5% If you aren't sure, please post your score below and we can calculate it for you. If both your Class 9 and Class 10 grades are displayed on your report card, REMEMBER that only Class 10 grades are used to calculate your CGPA.

i am from mumbai university & my pointer is 7.58 ,, please convert my pointers into percentage , according to mumbai university .

You have come this far from toddler to freaking soon-to-be-graduate, I am sure you can lookout at MHU website and find it out yourself too. Don't be lame, man.
