CGPA vs GPA
GPA stands for grade point average and CGPA for cumulative grade point average. Both turn letter grades or marks into numbers, but different countries and universities use different maximums: 4.0 is common in the United States, 10 in India and 5 or 7 in other systems. Converting between them lets you compare results or fill in an application that asks for a different scale.
CGPA to GPA formula
GPA = CGPA ÷ your scale × new scale
For a 10-point CGPA converted to a 4.0 GPA this is simply CGPA × 0.4.
Step-by-step example
Convert a CGPA of 8.2 out of 10 to a 4.0 scale.
| Step | Calculation | Result |
|---|---|---|
| 1. Find the share of the maximum | 8.2 ÷ 10 | 0.82 |
| 2. Multiply by the new scale | 0.82 × 4 | 3.28 |
Quick reference: 10-point CGPA to 4.0 GPA
| CGPA (out of 10) | GPA (out of 4.0) |
|---|---|
| 10.0 | 4.00 |
| 9.0 | 3.60 |
| 8.0 | 3.20 |
| 7.0 | 2.80 |
| 6.0 | 2.40 |
When the simple formula is not enough
Admissions offices and credential evaluators often convert grades course by course with their own tables, which can give a different number from a straight proportion. Use this calculator for a quick estimate and follow the instructions of the school or service you are applying to for anything official.
Common mistakes
- Using the wrong scale for your CGPA, such as entering a 4.0-scale result as if it were out of 10.
- Treating the result as an official transcript value.
- Rounding too early. Keep two decimals until the final answer.
How to use this calculator
- Enter your values. Convert a CGPA from one grading scale to another, such as a 10-point CGPA to a 4.0 GPA.
- Check units and assumptions. Make sure the inputs use the same scale and that any optional settings match your situation.
- Calculate and review. Compare the output with the formula below and note any limitations stated on the page.
Formula and calculation method
Use the conversion scale or grading method selected by your institution. There is no universally applicable CGPA-to-percentage or CGPA-to-GPA conversion across all schools, so the institution’s published policy takes precedence.
Worked example
For example, if your university publishes a specific CGPA conversion formula, enter the value using that scale rather than assuming a different university’s formula applies. Keep the original scale and the converted result together when reporting grades.
Search and practical tips
People commonly search for a cgpa to gpa calculator – convert to 4.0 scale, how to calculate the result step by step, which formula to use, and how to check the answer manually. Use the formula above as a transparent starting point, and consult the relevant institution, agency, or qualified professional when an official rule or personal circumstances affect the result.
Frequently asked questions
How do I convert CGPA to GPA?
Divide your CGPA by the maximum of its scale and multiply by the maximum of the GPA scale. For a 10-point CGPA converted to 4.0, multiply by 0.4.
What is 8.0 CGPA in a 4.0 GPA?
With the proportional method, 8.0 out of 10 is 3.2 on a 4.0 scale.
Is this the official conversion?
No. It is a straight proportional conversion. Many universities and credential evaluation services use their own grade tables, so check which method the school you are applying to expects.
What is the difference between CGPA and GPA?
GPA is the grade point average for a term or course load. CGPA is the cumulative average across all terms. The scale, such as 4.0 or 10, depends on the institution.
Can I convert from a 4.0 scale to a 10-point scale?
Yes. Choose 4 as your scale and 10 as the scale to convert to. A CGPA of 3.5 out of 4 becomes 8.75 out of 10.
