CGPA to GPA Converter — 10 Point Scale to US 4.0 Scale

How to Convert CGPA to US GPA (4.0 Scale)

If you are an international student applying to universities in the United States, you will often need to convert your local CGPA (such as the 10-point scale used in India, Germany, or other countries) to the standard US 4.0 scale. Our free converter provides a quick estimate using the standard mathematical formula.

Here is how to use the tool:

1. Enter your current CGPA — Input your score (e.g., 8.5).
2. Select your scale — Choose between a 10-point scale, 7-point scale, or custom scales.
3. Click “Convert CGPA” — The calculator will compute your estimated GPA on a 4.0 scale, percentage equivalent, and letter grade.

Formula for Converting 10-Point CGPA to 4.0 GPA

The standard mathematical formula to scale a 10-point CGPA to a 4.0 scale is:

GPA (4.0 Scale) = (Obtained CGPA ÷ Max CGPA Scale) × 4

For example, if your CGPA is 8.0 out of 10:

GPA = (8.0 ÷ 10) × 4 = 0.8 × 4 = 3.20

For percentage conversion under the Indian CBSE guidelines, the CGPA is multiplied by 9.5. For example, a CGPA of 8.0 translates to 8.0 × 9.5 = 76.0%.

WES (World Education Services) Evaluation vs. Mathematical Scaling

It’s important to understand that simple mathematical scaling is an approximation. Official credential evaluators like WES use a course-by-course evaluation method. Under WES guidelines:

• Individual subject grades are evaluated first.
• A local grade (like “Excellent” or “A”) is mapped directly to a US equivalent (A = 4.0, B = 3.0, etc.).
• The credits for each course are used as weights to calculate a cumulative GPA.
• This means a simple mathematical ratio might slightly differ from an official WES score, but it serves as an excellent reference point.

Practical Conversion Examples

Example 1: CGPA of 9.0 out of 10

Formula: (9.0 ÷ 10) × 4 = 3.60. Percentage (CBSE): 9.0 × 9.5 = 85.5%. US Letter Grade equivalent: A.

Example 2: CGPA of 7.5 out of 10

Formula: (7.5 ÷ 10) × 4 = 3.00. Percentage (CBSE): 7.5 × 9.5 = 71.25%. US Letter Grade equivalent: B.

Example 3: CGPA of 6.2 out of 7

On a 7-point scale: (6.2 ÷ 7) × 4 = 3.54. Percentage: (6.2 ÷ 7) × 100 = 88.6%. US Letter Grade equivalent: A-.

Frequently Asked Questions

What is a good CGPA out of 10?

Generally, a CGPA of 8.0 or above on a 10-point scale is considered very good. It converts to a 3.20 GPA, which meets the admission requirements for most top-tier international universities. A CGPA above 9.0 is excellent and puts you in a strong position for scholarships.

How does CBSE convert CGPA to percentage?

To convert CBSE CGPA to percentage, multiply your CGPA by 9.5. The board arrived at this multiplier by analyzing the average marks of candidates who scored in particular grade points over multiple years.

Can I use my mathematically scaled GPA for university applications?

Most US universities require an official evaluation from WES, ECE, or similar evaluation agencies. You should not use a self-calculated GPA on your official application unless the university explicitly asks you to do so. Use this tool for planning and evaluating your target universities.

Does WES count failed courses in the GPA calculation?

Yes. Even if your home university excludes failed courses or repeats from your final transcripts, evaluation agencies like WES generally compute all attempts when arriving at the final US-equivalent GPA.
