The official grade-to-point mapping, how it is applied, and where it comes from.
IUB publishes worked SGPA and CGPA formulas based on quality points divided by credit hours. The cited rules contain the grading table and a worked example showing the credit-weighted calculation.
Conversion shown: CGPA × 25 (mathematical normalization; not an official university conversion formula)

IUB uses the credit-weighted method. Grade point times credits gives quality points per course; total quality points divided by total credits gives the GPA. One practical note. If you are close to a threshold that decides funding or progression, get the number confirmed in writing before the deadline rather than after, because corrections after the fact are much harder to obtain.
Not unless IUB or the body receiving your application publishes that formula for your specific purpose. The multiplier is a convenience, and it carries no official standing.
A shared calculator would need one grade table. IUB has its own, so this page uses it. Check it against your own handbook before a deadline depends on the figure.
