The Official KTU Conversion Formula: 10 × CGPA - 3.75 (Circular Notification)
Per the official academic regulations issued by KTU (Notification Ref: KTU/A/456/2015), the official percentage conversion formula for B.Tech programs across Kerala is:
For example, a KTU B.Tech CSE graduate with an 8.10 CGPA converts to: (10 × 8.10) - 3.75 = 81.00 - 3.75 = 77.25%.
Why KTU Uses 10 × CGPA - 3.75 Instead of (CGPA - 0.75) × 10
Many universities subtract 0.75 and multiply by 10, which mathematically equals 10 × CGPA - 7.5. However, KTU chose the formula 10 × CGPA - 3.75:
- Reflecting Higher Grade Band Points: KTU awards Grade A (8.5 GP) and Grade A+ (9.0 GP) starting at 80% and 85% marks respectively. Subtracting 3.75 provides an exact linear fit with actual marks scored in University examinations.
- Fairness in IT Placements: Under
10 × CGPA - 3.75, a 6.375 CGPA qualifies for 60.00% placement eligibility, giving students a balanced conversion benchmark.

How to Calculate Cumulative CGPA from 8 Semester SGPAs
Cumulative CGPA is computed using the credit-weighted algorithm:
In the KTU 2019 scheme, a regular B.Tech program comprises 162 credits across 8 semesters, while the 2015 scheme comprised 182 credits.
KTU Degree Class Awards: Distinction (≥8.0 CGPA + 100 Points), First and Second Class
According to KTU Academic Regulations:
- First Class with Distinction (FCD): Final CGPA ≥ 8.00 (≥76.25%), passed all courses in first attempt within 4 years, and earned 100 Activity Points.
- First Class (FC): Final 6.50 ≤ CGPA < 8.00 (61.25% to 76.24%) with 100 Activity Points.
- Second Class / Pass: Final 5.50 ≤ CGPA < 6.50 with 100 Activity Points.
Step-by-Step Solved B.Tech 8-Semester Conversion Examples
Example 1: CET Trivandrum B.Tech ECE Graduate (CGPA: 8.42)
Consider a CET graduate with an 8.42 CGPA:
Calculation: (10 × 8.42) - 3.75 = 84.20 - 3.75 = 80.45%
Class Award: First Class with Distinction (FCD).
Example 2: Reverse Conversion (Target 65.00% for MNC Placement)
To find the CGPA required for a 65.00% aggregate in KTU:
Calculation: (65.00 + 3.75) / 10 = 68.75 / 10 = 6.88 CGPA
Impact on Technopark and Infopark Placements (TCS, UST 60%), GATE and Master's
Major technology employers operating across Technopark (Trivandrum) and Infopark (Kochi)—such as TCS, UST Global, Infosys, IBS Software, and Cognizant—require strict percentage cutoffs:
- 60.00% Placement Eligibility: Requires a minimum CGPA of 6.38.
- 65.00% Top Tech MNC Eligibility: Requires a minimum CGPA of 6.88.
- GATE and Higher Studies: IITs, IISc, and NITs accept direct CGPA scores. Check government fellowship eligibility on our scholarship eligibility tool.
Frequently Asked Questions (FAQs)
As per the official KTU Ordinance (Ref: Notification No. KTU/A/456/2015), the formula for converting 10-point CGPA to percentage for B.Tech, B.Arch, M.Tech, and MCA is: Percentage of Marks (%) = 10 × CGPA - 3.75.
In KTU, a student is awarded 'First Class with Distinction' if they achieve a final CGPA of 8.00 or higher, pass all examinations in the first attempt within 4 years, and successfully acquire a minimum of 100 mandatory student activity points.
To achieve exactly 60.00% marks under the KTU conversion formula [(60 + 3.75) / 10 = 6.375], a student requires a minimum CGPA of 6.38 (First Class).
CGPA is calculated using the credit-weighted sum of SGPAs: CGPA = Σ(SGPA of Semester i × Credits of Semester i) / Σ(Total B.Tech Credits across 8 semesters, ~160 to 182 credits).
Every KTU B.Tech student must earn a minimum of 100 activity points (75 points for lateral entry students) through co-curricular, NSS/NCC, sports, and technical events to qualify for the award of the degree.
Under KTU B.Tech academic regulations, the minimum passing CGPA for the award of a B.Tech degree is 5.50 (equivalent to 51.25% marks).
