10-Point to 4-Point GPA Calculator
Convert an Indian 10-point CGPA to a US-style 4.0 GPA — and reverse — with a clear linear estimate used on many applications.
Linear estimate: GPA4 = (CGPA ÷ 10) × 4. Credential evaluators (e.g. WES) may use course-by-course evaluation instead of a flat conversion.
How 10-point CGPA maps to 4.0 GPA
The linear estimate
GPA4 = (CGPA ÷ 10) × 4, and the reverse is CGPA10 = (GPA ÷ 4) × 10. An 8.0 CGPA becomes 3.20; a 3.5 GPA becomes 8.75.
Linear estimate: GPA4 = (CGPA ÷ 10) × 4. Credential evaluators (e.g. WES) may use course-by-course evaluation instead of a flat conversion.
Credential evaluation caveat
WES and similar evaluators may ignore a flat conversion and instead evaluate individual courses. If you need an official evaluation for admissions or licensing, follow that agency's process rather than relying solely on this estimate.
Need percentage instead?
Use the CGPA to Percentage Calculator with your university's formula (CBSE, VTU, Anna, Mumbai, DU, or custom). Percentage and 4.0 GPA are different destination formats.
Frequently asked questions
How do I convert a 10-point CGPA to a 4.0 GPA?
A common linear estimate is GPA4 = (CGPA ÷ 10) × 4. For example, an 8.5 CGPA converts to (8.5 ÷ 10) × 4 = 3.40 on the 4.0 scale.
Is this what WES or foreign universities use?
Often not exactly. Many credential evaluators (including WES) perform course-by-course evaluation rather than applying a flat scale conversion. Treat this as an application estimate and confirm with the evaluator or university.
Can I convert a 4.0 GPA back to a 10-point CGPA?
Yes — switch modes. CGPA10 = (GPA ÷ 4) × 10. A 3.2 GPA becomes 8.00 on the 10-point scale under the same linear rule.
Is this the same as converting CGPA to percentage?
No. CGPA→percentage uses university-specific multipliers (e.g. CBSE ×9.5, Anna ×10, VTU's offset formula). This tool only remaps the scale between 10-point and 4.0 GPA.
Why do some sites use different conversion tables?
Some publishers map Indian letter grades or percentage bands to US letter grades before assigning GPA points. Those tables are not universal. This page documents one transparent linear estimate so you can see the math.
