FAQs:

The standard formula for converting CGPA to percentage is:

Percentage = CGPA × 9.5 (for 10-point scale)

Example: If your CGPA is 8.2, then 8.2 × 9.5 = 77.9%

This formula is widely accepted across most Indian universities.

Conversion depends on your university’s grading system:

1. 10-point scale: Multiply CGPA by 9.5
2. 4-point scale: Multiply CGPA by 25 (or divide by 4 then multiply by 100)
3. Other scales: (CGPA ÷ scale maximum) × 100

To calculate percentage from CGPA:

1. Identify your university’s grading scale (usually 10 or 4)
2. For 10-point scale: Percentage = CGPA × 9.5
3. For 4-point scale: Percentage = (CGPA × 100) ÷ 4
4. Round off to two decimal places if needed

The calculation method varies by institution:

• Most Indian universities: CGPA × 9.5
• CBSE 10th standard: CGPA × 9.5
• US universities (4-point): CGPA × 25
• Engineering colleges: Often CGPA × 10

To convert percentage back to CGPA:

For 10-point scale: CGPA = Percentage ÷ 9.5

For 4-point scale: CGPA = (Percentage ÷ 100) × 4

Example: 85% would be 85 ÷ 9.5 = 8.95 CGPA (10-point scale)

Reverse conversion formulas:

1. 10-point scale: CGPA = Percentage ÷ 9.5
2. 4-point scale: CGPA = Percentage ÷ 25
3. Custom scales: CGPA = (Percentage × scale maximum) ÷ 100

College-specific methods:

• Check your college’s academic regulations
• Most use CGPA × 9.5 or CGPA × 10
• Some colleges provide conversion tables
• Engineering colleges often have specific formulas
• Contact your examination cell for official formula

Step-by-step calculation:

1. Confirm your CGPA scale (usually 4 or 10)
2. Multiply by appropriate factor (9.5 for 10-point)
3. For 4-point: (CGPA ÷ 4) × 100
4. Example: 3.6 CGPA (4-point) → (3.6 ÷ 4) × 100 = 90%

Percentage to CGPA conversion:

Standard method:

• 10-point scale: Divide percentage by 9.5
• 4-point scale: Divide percentage by 25
• Example: 76% → 76 ÷ 9.5 = 8.0 CGPA

Calculation methods:

• General formula: CGPA × Conversion factor
• Conversion factors vary:
  • 9.5 for most Indian universities
  • 10 for VTU and some engineering colleges
  • 25 for 4-point scale (US system)

For 4-point scale systems:

Percentage = (CGPA ÷ 4) × 100

Example conversions:

• 3.0 CGPA → (3.0 ÷ 4) × 100 = 75%
• 3.5 CGPA → (3.5 ÷ 4) × 100 = 87.5%
• 2.8 CGPA → (2.8 ÷ 4) × 100 = 70%

Reverse calculation methods:

Calculation depends on institution:

• Standard method: CGPA × 9.5
• Engineering colleges: Often CGPA × 10
• Mumbai University: (CGPA – 0.75) × 10
• Anna University: (CGPA × 10) – 7.5

Methods to determine percentage:

1. Identify your university’s conversion policy
2. Use standard formula (CGPA × 9.5) if unsure
3. For precise calculation, check academic handbook
4. Contact your university’s examination office

Percentage → CGPA conversion:

General guidelines:

• 10-point scale: Divide by 9.5
• 4-point scale: Divide by 25
• VTU: Divide by 10
• SPPU: (Percentage ÷ 10) + 0.75

Conversion process:

1. Determine your university’s grading scale
2. Apply appropriate multiplication factor
3. For 10-point: × 9.5
4. For 4-point: × 25
5. For custom scales: (CGPA ÷ scale max) × 100

Equivalent percentage calculation:

Standard formula: Percentage = CGPA × Conversion Factor

Common conversion factors:

• 9.5 – Most Indian universities
• 10 – VTU, JNTU
• 25 – 4-point scale (3.6 CGPA = 90%)
• University-specific factors may apply

Percentage equivalent calculation:

For 10-point CGPA:

• Multiply CGPA by 9.5
• Example: 7.8 CGPA × 9.5 = 74.1%

For 4-point CGPA:

• Multiply CGPA by 25
• Example: 3.2 CGPA × 25 = 80%

Engineering college methods:

• VTU: CGPA × 10
• Anna University: (CGPA × 10) – 7.5
• KTU: (CGPA × 10) + 5
• SPPU: (CGPA – 0.75) × 10
• Most private colleges: CGPA × 9.5

Calculation method:

1. Identify your university’s CGPA system
2. For semester system: Calculate SGPA first, then average
3. Multiply final CGPA by conversion factor
4. Common factors: 9.5, 10, or university-specific

Ways to obtain percentage equivalent:

• Calculate using standard formula (CGPA × 9.5)
• Request conversion certificate from university
• Check academic transcript for percentage equivalent
• Consult university’s examination department

Determining percentage equivalent:

Standard calculation:

• 10-point scale: CGPA × 9.5
• 4-point scale: CGPA × 25

University-specific examples:

• Mumbai University: (CGPA – 0.75) × 10
• Anna University: (CGPA × 10) – 7.5

Mumbai University specific formula:

Percentage = (CGPA – 0.75) × 10

Example calculation:

1. If CGPA is 7.8
2. Subtract 0.75: 7.8 – 0.75 = 7.05
3. Multiply by 10: 7.05 × 10 = 70.5%

This formula applies to most undergraduate programs at Mumbai University.

Reverse calculation methods:

CBSE 10th standard conversion:

Percentage = CGPA × 9.5

Example:

• CGPA 9.2 → 9.2 × 9.5 = 87.4%
• CGPA 8.6 → 8.6 × 9.5 = 81.7%

Note: This formula is officially provided by CBSE and only applies to 10th standard results.

Step-by-step calculation guide:

1. Confirm your CGPA scale (4, 10, or other)
2. Identify your institution’s conversion formula
3. Apply the appropriate multiplication factor
4. For 10-point: × 9.5 (or × 10 for some universities)
5. For 4-point: × 25
6. Round off to two decimal places if needed

VTU (Visvesvaraya Technological University) method:

Percentage = CGPA × 10

Example:

• 7.5 CGPA → 7.5 × 10 = 75%
• 8.3 CGPA → 8.3 × 10 = 83%

This direct multiplication by 10 is specific to VTU and differs from the standard 9.5 multiplier used by most other universities.

• CGPA 7.2 → (7.2 – 0.75) × 10 = 64.5%

This formula applies to most undergraduate programs at SPPU.

For graduation programs:

• Arts/Science/Commerce: Typically CGPA × 9.5
• Engineering: Often CGPA × 10
• Professional courses: Check university guidelines
• Some universities award class based on CGPA ranges
