Short answer. A University of Mumbai circular of October 2018 gives, for the 10 point grading system, Percentage = 7.25 x CGPI + 11, rounded to the next full integer. A CGPI of 8.0 gives 69%.
The official formula
Percentage = 7.25 x CGPI + 11, rounded to the next full integer
The 2018 circular says that for the 10 Point Grading System (CBCS) the percentage is 7.25 x CGPI + 11. The percentage can be calculated with this formula and rounded to the next full integer. For the 7 point Grading System (CBGS), the percentage is taken from the actual marks.
Where it comes from
The circular was issued by the Board of Examinations and Evaluation of the University of Mumbai. It says the committee's resolution was approved at a meeting held on 4 September 2018 and applies to graduate and postgraduate choice based courses from the academic year 2016-17. An earlier circular of 19 June 2017 used 7.1 x CGPA + 11, after a committee meeting of 20 May 2017. The 2018 text replaces the figure 7.1 with 7.25.

Who it applies to
The circulars are addressed to Arts, Science, Commerce and Management colleges and institutions of the university. We do not state what applies to other faculties such as engineering, because the documents we read do not say.
How to use the tool
Type your CGPA in the box. Pick the formula that matches your scheme first. The tool shows the percentage and a short table of nearby values. Always compare the answer with your marksheet or a certificate from the Mumbai University office, because only they can give the official figure.
Things to watch
Both circulars say the conversion is only an approximate representation, because CGPI is a weighted average and cannot be tied exactly to actual marks.
The circulars add that CGPI can be used everywhere, since the grading system is in force. The formula is for cases that need a percentage.

Going the other way
Forms often ask for a minimum percentage. Under the Mumbai University rule on this page, 60% needs a CGPA of about 6.76; 70% needs a CGPA of about 8.14; 75% needs a CGPA of about 8.83. These are plain reversals of the formula. They show what CGPA you would need to clear a percentage cut-off, but the form may ask for the university's own certificate.
How it compares
At a CGPA of 8, the Mumbai University rule gives 69%. For the same number, CBSE gives 76%, VTU gives 72.5%, JNTUH gives 75%. The spread is the reason to use only the rule of the body that gave you the CGPA. Our CGPA to percentage hub lists every rule we have checked.
Worked example
Example. A Mumbai University student has a CGPA of 8.
7.25 x 8 + 11 = 69.00%. Rounded up to the next whole number: 69%.
Questions
Why does the page show two Mumbai formulas?
The university issued 7.1 x CGPA + 11 in June 2017 and 7.25 x CGPI + 11 in 2018. The later circular is the latest we read.
Do I round up or down?
The circulars say the result can be rounded to the next full integer. The tool shows both the exact figure and the rounded-up figure.
What if my programme is on the 7 point scale?
The circulars say percentage for the 7 point CBGS comes from the actual marks, not from a formula.
Is this the official Mumbai University conversion?
It follows the document linked on this page, which we read on 2026-10-10. For a certificate or a form that needs the official figure, ask the Mumbai University office.
Can I use the Mumbai University formula for another university?
No. Each board and university sets its own rule. At a CGPA of 8.0 the rules in this series give anything from 69% to 85%. Use the page for your own university.
What if my marksheet shows both a CGPA and a percentage?
Use the percentage on the marksheet. It is the university's own figure, and it overrides any conversion from a tool.
