SGPA to Percentage Calculator — Compare Common Conversion Rules

SGPA means Semester Grade Point Average. It is your credit-weighted average for one semester, usually on a 10-point scale. Colleges and employers often ask for a percentage instead, so you need to convert it. There is no single national formula for this. Each university sets its own rule, which is why websites give different answers for the same SGPA. The three rules you will see most often are: × 9.5: multiply your SGPA by 9.5. This comes from the CBSE rule for CGPA, and many colleges use it too. × 10: multiply your SGPA by 10. This is the simplest rule, and it gives the highest answer of the three. (SGPA − 0.75) × 10: subtract 0.75, then multiply by 10. This rule is often quoted for VTU and other engineering universities, though sources do not all agree, so please confirm it. The rule makes a real difference. For an SGPA of 8.2, the three answers range from 74.5% to 82%. That gap can decide whether you clear a 75% eligibility cutoff, so never guess. Check the back of your marksheet, your university's ordinance or notification, or ask your exam office. If your university gives you a different multiplier, choose the custom option and enter it. To get one percentage for your whole degree, do not average the percentages from each semester. First work out your CGPA from all your semesters, weighted by credits, and then convert the CGPA using your university's rule. If the semesters have equal credits, your CGPA is simply the average of your SGPAs. SGPAs of 7.8 and 8.6 give a CGPA of 8.2.
