In today’s academic world, GPA, SGPA, and CGPA are three of the most commonly used terms yet they often confuse students. When you see your marksheet saying “SGPA: 8.25” or “GPA: 3.7/4”, you may wonder are they the same thing or different?
Let’s clear the confusion once and for all. In this article, you’ll learn,
- The real difference between SGPA and GPA
- How both are calculated (with formulas & examples)
- Their importance for college, jobs, and foreign university admissions
- SGPA to GPA conversion (especially for Indian students applying abroad)
SGPA
SGPA stands for Semester Grade Point Average. It represents your academic performance in one specific semester.
Each subject or course you study in a semester has,
- A certain credit weight (based on hours or importance)
- A grade (like A, B+, C, etc.)
- A grade point (numerical value of the grade)
The SGPA is calculated by taking a weighted average of all the grade points, based on their respective credits.
Formula for SGPA (10-point scale):
SGPA = Σ(Credit×Grade Point) / Σ(Credits)
Example of SGPA Calculation (Indian 10-point System)
| Subject | Credits | Grade | Grade Point |
|---|---|---|---|
| Thermodynamics | 4 | A | 9 |
| Fluid Mechanics | 3 | B+ | 8 |
| Machine Design | 4 | A+ | 10 |
| Mathematics | 3 | B | 7 |
Step 1: Multiply each grade point by its credit
(9×4) + (8×3) + (10×4) + (7×3) = 36 + 24 + 40 + 21 = 121
Step 2: Divide by total credits (4+3+4+3 = 14)
SGPA = 121 ÷ 14 = 8.64
So your SGPA for that semester = 8.64 / 10
GPA
GPA stands for Grade Point Average. It is a more general term used globally to represent your average academic performance, typically on a 4.0 scale.
Unlike SGPA, which focuses on one semester, GPA may refer to,
- Your average for one semester (Semester GPA), or
- Your average across all semesters (Cumulative GPA), depending on context.
Formula for GPA (4.0 scale):
GPA = Σ(Credit Hours×Grade Points) / Σ(Credit Hours)
Each grade has a numerical value for example,
A = 4.0, A− = 3.7, B+ = 3.3, B = 3.0, C = 2.0, D = 1.0, F = 0.
Difference of SGPA vs GPA
| Basis | SGPA | GPA |
|---|---|---|
| Full Form | Semester Grade Point Average | Grade Point Average |
| Meaning | Average grade points in one semester | Average grade points in all courses or semesters |
| Scale | Usually 10-point (India, Asia) | 4.0-point (U.S., Canada, etc.) |
| Duration | One specific semester | Semester, yearly, or cumulative average |
| Used In | India, Asia, some UK universities | U.S., Canada, Europe, Australia |
| Conversion | CGPA × 9.5 = % (India) | GPA × 25 = % (approx.) |
| Example | 8.5 / 10 | 3.5 / 4 |
💡 In simple words:
- SGPA = One semester’s score
- GPA = General or overall academic score
So, when your Indian marksheet says “SGPA = 8.3”, it’s equivalent to about “GPA = 3.3” in U.S. universities.
How SGPA Is Used in India?
In Indian universities under AICTE / UGC / GTU / VTU / Anna University, SGPA is the standard semester grading metric.
It’s used to calculate,
- Your semester result
- Your overall CGPA (Cumulative Grade Point Average)
The CGPA is then printed on your final degree certificate, often along with percentage conversion.
Conversion Formula:
Percentage = CGPA×9.5
So, a CGPA of 8.2 = 77.9%
SGPA to GPA Conversion (Approximate Method)
Many Indian students need to convert SGPA to GPA while applying abroad. Here’s a simple approximation formula used globally,
GPA (4.0) = (SGPA÷10)×4
Example:
If your SGPA = 8.2
then GPA = (8.2 ÷ 10) × 4 = 3.28 / 4.0
Always mention both,
SGPA: 8.2 / 10 (≈ GPA 3.28 / 4.0)
It looks professional and transparent in resumes or SOPs.
Conclusion
The confusion between SGPA and GPA exists mainly because different countries follow different grading scales.
But at their core, both mean the same thing your academic average.
- SGPA shows your semester performance,
- GPA reflects your overall or international equivalent performance.
If you’re studying in India, track your SGPA each semester and use a CGPA calculator to monitor your overall performance. And if you’re planning to study abroad, use a GPA conversion chart or an official WES evaluation to present your grades accurately.
Remember numbers matter, but growth and consistency matter even more. Keep learning, keep improving, and your GPA will naturally follow.
