CGPA to GPA Converter – Free Tool for International Applications

Last Updated: September 2026

Use this free CGPA to GPA Converter to instantly translate your Cumulative Grade Point Average from a 10-point, 5-point, 7-point, or percentage scale into an estimated US 4.0 GPA. The tool uses a linear conversion formula for quick self-assessment and provides a WES-style estimate where available. No sign-up required, and nothing you enter is saved.

🌍 CGPA to GPA Converter for International Applications

Convert your CGPA on any common scale to an estimated US 4.0 GPA. Includes linear conversion and WES‑style estimates where available.

📋 Linear conversion provides a rough estimate. WES and ECE use course‑by‑course evaluation for official reports.

How to Use This CGPA to GPA Converter

The converter is designed for speed and simplicity. Here is exactly what each field does and how the calculation works:

  1. Your CGPA: Enter your cumulative grade point average as it appears on your transcript or degree certificate. This should be the overall average across all semesters, not a single semester’s GPA.
  2. Scale: Select the grading scale your institution uses. Common options include 10-point (India), 5-point (Nigeria), 4-point (US-style), 7-point (Australia), and percentage. The tool uses this to determine the correct conversion formula.
  3. Convert to US GPA: Click this button to run the conversion. The tool applies a linear formula (your CGPA ÷ maximum scale × 4) and, where available for your selected scale, a WES-style estimate based on typical credential evaluation patterns.

The result is displayed instantly below the button. The tool shows both the linear estimate and, for supported scales, a WES-style estimate side by side so you can see the range.

Understanding Your Results: Linear vs. WES-Style Estimates

The converter provides two types of output. It is important to understand the difference before you use either figure in an application.

Estimate Type How It’s Calculated Best Used For
Linear Estimate CGPA ÷ Maximum Scale × 4. This is a simple proportional conversion. Quick self-assessment and preliminary shortlisting. It is not an official GPA.
WES-Style Estimate Based on typical patterns observed in official WES evaluations for your country’s grading scale. WES uses a course-by-course evaluation, not a single formula. A more realistic preview of how a credential evaluator might interpret your grades.

Why the two estimates can differ: The linear method assumes all grades convert proportionally. WES and ECE use a course-by-course evaluation that accounts for the difficulty of your institution and grading patterns in your country. For strong students from rigorous universities, the WES-style estimate is often higher than the linear estimate.

What This Converter Does — and What It Doesn’t

This tool is a starting point for self-assessment, not an official evaluation. Here is what it covers and what you still need to do separately.

Situation Handled by This Tool?
Linear CGPA-to-GPA conversion for any common scale Yes
WES-style estimates for supported scales Yes — where available
Course-by-course GPA calculation No — requires official evaluation
Official WES/ECE report for university applications No — apply directly to the agency
Semester-specific GPA or major GPA No — this tool uses your cumulative CGPA

If you need an official GPA for a graduate school application: Most US universities require a course-by-course evaluation from a NACES-member agency such as WES or ECE. These evaluations convert each course’s grade and credit separately and calculate a cumulative GPA on a 4.0 scale. The process typically takes 7 business days after all documents are received.

If your grades are in percentage form: Use our Percentage to GPA Converter first, then enter the resulting letter grade into this tool if your university uses a scale-based system.

Frequently Asked Questions About This Tool

Why doesn’t my converted GPA match my WES report? ▼
The most common reason is the difference between a linear conversion and a course-by-course evaluation. This tool applies a single formula to your CGPA, while WES evaluates each course individually, considering the credit weight and the grade earned. WES also uses country-specific grading standards that account for institutional difficulty. For strong students from competitive universities, the official WES GPA is often higher than the linear estimate.
Can I use this converted GPA for my university applications? ▼
It depends on the university. Some US universities accept self-reported GPAs for the initial application and only require an official evaluation if you are admitted. Others require a NACES-member evaluation upfront. Check your target university’s admissions page to see their specific requirement. If they require an official evaluation, you will need to apply to WES, ECE, or another approved agency.
Is a 7.5 CGPA on a 10-point scale a 3.0 GPA? ▼
Using the linear method, 7.5 ÷ 10 × 4 = 3.0. However, a WES-style evaluation often produces a higher result for Indian students in this range. Many WES evaluations place a 7.5–8.4 CGPA in the 3.3–3.5 range. The linear method is a conservative estimate, not a ceiling.
What is the difference between WES and ECE? ▼
Both are NACES-member credential evaluation agencies, but they have different report types and conversion methodologies. WES is the larger and more widely recognized agency, and its Course-by-Course (CxC) report is the standard for graduate admissions. ECE offers a “General with GPA” report that provides a cumulative grade average. Your target university will specify which agency and report type they accept.
Does this tool save or send my grades anywhere? ▼
No. All calculations are performed locally in your browser. Nothing you enter — including your CGPA or scale selection — is saved or sent anywhere. You can safely use the tool without privacy concerns.
Is this converter free, and do I need to sign up? ▼
Yes, it is completely free with no sign-up or account required. Just enter your CGPA and scale, and the result appears instantly.
Disclaimer: This converter provides an estimate using a linear formula and, where available, a WES-style pattern-based estimate. It is not an official credential evaluation and does not replace a course-by-course report from a NACES-member agency. Grading scales vary by institution and country, and official evaluations may produce different results. Always verify your target university’s specific requirements and, if required, apply for an official evaluation through WES, ECE, or another NACES-member agency.
