How to Convert CGPA to GPA on the US 4.0 Scale
Indian universities grade on a 10-point CGPA scale, while US universities use a 4.0 GPA scale. If you are an Indian student applying to graduate programs in the United States, you need to convert your CGPA to the US equivalent so admissions committees can evaluate your academic record alongside applicants from other countries.
The standard conversion formula accepted by most US institutions is straightforward: divide your CGPA by 10, then multiply by 4. This linear conversion maps the Indian 10-point scale proportionally onto the US 4.0 scale.
US GPA = (CGPA ÷ 10) × 4
CGPA to Percentage (CBSE):
Percentage = CGPA × 9.5
Example: Priya has a CGPA of 8.2 from VTU.
US GPA = (8.2 ÷ 10) × 4 = 3.28 GPA
CBSE Percentage = 8.2 × 9.5 = 77.9%
US Letter Grade = B
The CBSE percentage formula (CGPA × 9.5) is specific to the Central Board of Secondary Education and is officially published by CBSE for Class 10 results. Other universities use different percentage mappings, which is why our calculator includes university-specific dropdown options. Always use the formula that matches your institution.
Indian vs US Grading: What You Need to Know
The Indian and US grading systems differ in several fundamental ways beyond the scale numbers. Understanding these differences helps you present your academic record accurately on applications and avoid common conversion mistakes.
Scale and Letter Grades
Indian CGPA runs from 0 to 10, with grades like O (Outstanding), A+, A, B+, B, C, and F. The US GPA runs from 0 to 4.0, using A through F letter grades with plus/minus modifiers. An Indian A+ (typically 9.0+) maps to roughly a US A- (3.7), not a US A+ (4.0). This difference trips up many students who assume the letters are equivalent across systems.
Grading Strictness
Indian universities are generally considered stricter graders than US institutions. A 75% score at an Indian engineering college often represents the same competency as an 85% at a US university. Many US admissions committees are aware of this difference, which is one reason WES evaluations sometimes convert Indian grades slightly higher than the straight formula suggests. Our GPA calculator can help you model how your converted grades affect your overall US GPA once you start taking courses in the US.
University-Specific Conversion Differences
Not every Indian university calculates CGPA the same way, and percentage equivalents vary significantly between institutions. Using the wrong formula can misrepresent your academic record.
- CBSE: Percentage = CGPA × 9.5. This is the most widely known formula, officially published by the Central Board.
- Anna University: Uses a 10-point scale with grades O (91-100), A+ (81-90), A (71-80), B+ (61-70), B (51-60). Their CGPA-to-percentage mapping follows the grade midpoints rather than a linear formula.
- VTU (Visvesvaraya Technological University): Uses 10-point CGPA where S (Outstanding) = 10, A = 9, B = 8, C = 7, D = 6, E = 4 (pass). Percentage conversion follows its own grading document.
- Mumbai University: Uses a 10-point scale with O (10), A+ (9), A (8), B+ (7), B (6), C (5), P (4). Their percentage bands differ from CBSE significantly.
Tips for Indian Students Applying to US Universities
- Get a WES evaluation early. World Education Services takes 7-20 business days. Start the process months before application deadlines, not weeks. A WES-evaluated transcript carries more weight than a self-converted CGPA.
- Check each university’s conversion policy. Some schools specify their own formula on the admissions page. Stanford, MIT, and many other top schools state they evaluate transcripts in context rather than converting to a 4.0 scale.
- Do not round up aggressively. If your converted GPA is 2.98, do not write 3.0. Admissions committees will verify, and rounding up can raise trust concerns.
- Include context for low GPAs. If your CGPA is below 7.0, explain any extenuating circumstances (heavy course load, research involvement, university grading curve) in your statement of purpose.
Common Mistakes When Converting CGPA to GPA
- Using the wrong percentage formula: CBSE’s 9.5 multiplier only applies to CBSE. VTU, Anna, and Mumbai have different mappings. Always match the formula to your institution.
- Confusing CGPA with SGPA: CGPA is cumulative across all semesters. SGPA (Semester GPA) is for a single semester. US applications ask for the cumulative figure.
- Assuming a 10-point CGPA equals 100%: A CGPA of 10 converts to 95% under CBSE’s formula (10 × 9.5), not 100%. This is because the 9.5 multiplier accounts for CBSE’s grading distribution.
- Not checking the target school’s policy: Some US universities have their own conversion tables or require WES evaluations. Using a generic formula when the school specifies its own method can hurt your application. Use our grade converter to verify your results across multiple scales.
- Ignoring the difference between CGPA and percentage: Many students list their percentage when the application asks for CGPA, or vice versa. These are different numbers derived differently. A CGPA of 8.0 becomes 76% under CBSE (8 × 9.5) but might be 80% under Anna University (8 × 10). Read the application form carefully and provide exactly the format requested.
