What formula is used to convert a 10-point Indian CGPA to a US 4.0 GPA?

The formula looks deceptively simple, but the two operations doing the work, dividing by 10 and multiplying by 4, only hold up if your university actually grades on a straight, unweighted 10-point scale rather than a relative or credit-weighted one, which is exactly where students most often get tripped up.

The Formula Step by Step

US GPA equals CGPA divided by 10, multiplied by 4. Worked example: an 8.0 CGPA divided by 10 gives 0.8, multiplied by 4 gives a US GPA of 3.2. A 9.0 CGPA using the same steps produces a US GPA of 3.6.

When This Formula Does Not Apply Cleanly

• Relative grading: Some Indian universities grade on a curve rather than an absolute 10-point scale.
• Weighted credits: Programs with heavily weighted core subjects can distort a simple average.
• Percentage-based transcripts: These typically convert to CGPA first, commonly by dividing your percentage by 9.5, before this formula applies.

My Advice

Treat this formula as a fast estimate for shortlisting, not as the number you submit on a formal application. If a specific university or a centralized evaluator like WES requires an official conversion, use their process directly, since their method can differ meaningfully from this general purpose formula, sometimes by more than a full grade band once course weighting and grading distribution are both factored in.
