Grading Scale Formulas
| Scale | Formula | Notes |
|---|---|---|
| 4.0 Scale (US) | CGPA = ∑(Grade Points × Credit Hours) / ∑(Credit Hours) | A=4.0, A-=3.7, B+=3.3, B=3.0, etc. |
| 5.0 Scale (India) | CGPA = ∑(Grade Points × Credit Hours) / ∑(Credit Hours) | O=5.0, A+=4.5, A=4.0, B+=3.5, etc. |
| 10.0 Scale (Global) | CGPA = ∑(Grade Points × Credit Hours) / ∑(Credit Hours) | Direct grade points from 0.0 to 10.0 |
| Percentage | Percentage = ∑(Percentage × Credit Hours) / ∑(Credit Hours) | Direct percentage from 0% to 100% |
Scale Conversion Formulas
4.0 Scale to Other Scales:
- To 5.0 Scale: CGPA_5.0 = (CGPA_4.0 / 4.0) × 5.0
- To 10.0 Scale: CGPA_10.0 = (CGPA_4.0 / 4.0) × 10.0
- To Percentage: Percentage = (CGPA_4.0 / 4.0) × 100%
5.0 Scale to Other Scales:
- To 4.0 Scale: CGPA_4.0 = (CGPA_5.0 / 5.0) × 4.0
- To 10.0 Scale: CGPA_10.0 = (CGPA_5.0 / 5.0) × 10.0
- To Percentage: Percentage = (CGPA_5.0 / 5.0) × 100%
10.0 Scale to Other Scales:
- To 4.0 Scale: CGPA_4.0 = (CGPA_10.0 / 10.0) × 4.0
- To 5.0 Scale: CGPA_5.0 = (CGPA_10.0 / 10.0) × 5.0
- To Percentage: Percentage = (CGPA_10.0 / 10.0) × 100%
Percentage to Other Scales:
- To 4.0 Scale: CGPA_4.0 = (Percentage / 100%) × 4.0
- To 5.0 Scale: CGPA_5.0 = (Percentage / 100%) × 5.0
- To 10.0 Scale: CGPA_10.0 = (Percentage / 100%) × 10.0
Technical Notes:
- All calculations are performed in real-time using client-side JavaScript
- Results are rounded to two decimal places for readability
- Grade conversions use linear mapping and may not account for institutional curve adjustments
- No data is stored on external servers; all calculations remain local to your device
Practical Examples
Example 1: 4.0 Scale Calculation
A student takes 4 courses with the following grades:
| Course | Credits | Grade | Points |
|---|---|---|---|
| Mathematics | 3 | A (4.0) | 12.0 |
| Physics | 4 | B+ (3.3) | 13.2 |
| History | 3 | A- (3.7) | 11.1 |
| English | 2 | B (3.0) | 6.0 |
| Total | 12 | - | 42.3 |
Calculation:
CGPA = Total Points / Total Credits
CGPA = 42.3 / 12 = 3.53
Final CGPA (4.0 scale): 3.53
Example 2: Percentage to Other Scales
A student has an overall percentage of 85% and wants to convert to other scales:
Given:
Overall Percentage: 85%
To 4.0 Scale:
CGPA_4.0 = (85% / 100%) × 4.0
CGPA_4.0 = 0.85 × 4.0 = 3.40
To 5.0 Scale:
CGPA_5.0 = (85% / 100%) × 5.0
CGPA_5.0 = 0.85 × 5.0 = 4.25
To 10.0 Scale:
CGPA_10.0 = (85% / 100%) × 10.0
CGPA_10.0 = 0.85 × 10.0 = 8.50
Frequently Asked Questions
CGPA (Grade Point Average) is calculated by dividing the total number of quality points earned by the total number of credit hours attempted. Each grade is assigned a numerical value (e.g., A=4.0, B=3.0), which is then multiplied by the credit hours for the course to get quality points. The formula is:
CGPA = Sum of (Grade Points × Credit Hours) / Sum of Credit Hours
GPA (Grade Point Average) typically refers to your average for a single semester or term. CGPA (Cumulative Grade Point Average) refers to the overall average of all your semesters or terms combined. Our calculator can help you calculate both depending on the input data provided.
Our conversions follow standard mathematical formulas for translating between different scales. However, different institutions may have specific policies for converting grades. The conversions provided are approximations and may not exactly match official institutional conversions. For official purposes, always check with your academic institution.
Yes, you can download your results as a text file or share them via WhatsApp. However, the calculator doesn't store your data between sessions. If you want to keep a record, be sure to use one of the export options before closing the calculator.
To calculate your CGPA across multiple semesters, you should use all courses from all semesters. Input each course with its credit hours and grade. The calculator will provide the cumulative GPA based on all courses entered. Alternatively, you can use the weighted average of your semester GPAs if you know the total credit hours for each semester.
This calculator does not automatically handle course retakes or replacements. For retaken courses, follow your institution's policy. Some schools only count the highest grade, while others average both attempts or count only the most recent grade. You should manually enter the grade that should be counted according to your institution's policy.
