FAQ
What is the most common percentage to CGPA formula?
A common rule is CGPA = Percentage ÷ 9.5 (often used in CBSE contexts), but many institutions use different conversions.
Is percentage to CGPA conversion universal?
No. Different boards and universities use different divisors, scales, or mapping tables, so always confirm the official rule for your program.
Can I convert to a 4.0 scale using this tool?
Yes—choose the 4.0 linear option (CGPA = Percentage × 4/100) or set a custom max scale if your school specifies one.
What percentage range is allowed?
This tool accepts values from 0 to 100. If your input is outside that range, it will show an error.
Does the tool round CGPA?
Yes, the displayed CGPA is rounded to 2 decimals for clean reporting.
My university gave a custom divisor. How do I use it?
Select Custom divisor and enter the divisor exactly as provided (for example, 9.0, 9.5, or 10).
Why does my result differ from another website?
Most differences come from using a different formula (÷9.5 vs ÷10 vs a scale mapping) or from rounding rules.
