What is a GPA?

A GPA scale converter lets you translate a grade point average between the three most common academic grading systems: the US 4.0 GPA scale, the Indian 10.0 CGPA scale, and percentage marks. Whether you are an Indian student applying to US universities, an employer evaluating transcripts from different educational systems, or a student comparing grades across semesters graded on different scales, this converter gives you the equivalent value instantly.

The 4.0 GPA scale is the standard at nearly all US universities. A 4.0 is a perfect grade, 3.0 is a B average, and 2.0 is typically the minimum for academic standing. The 10.0 CGPA scale is used by most Indian universities affiliated with boards such as CBSE, AICTE, and many state universities. A CGPA of 10.0 is a perfect score and 7.0–7.5 is generally considered good academic standing.

Percentage marks — the traditional Indian grading format — remain the most universally understood format across Indian schools, competitive exams, and government recruitment. Many job applications and government service applications still require percentage marks, even when the university issued grades as CGPA.

Converting between these three systems requires a linear approximation because the relationship between letter grades, percentage marks, and GPA points is not universally standardised. The converter uses the widely accepted formulas: GPA (4.0) = Percentage × 0.04 and CGPA (10.0) = GPA (4.0) ÷ 0.4. These are useful for general comparison but should be treated as approximations when used for official admissions or HR decisions.

How to use this GPA calculator

  1. Select the From scale — choose whether you are starting from a GPA (4.0), CGPA (10.0), or Percentage.
  2. Select the To scale — choose the scale you want to convert into.
  3. Enter your grade value in the input field. The converter accepts decimal values (e.g. 8.6, 3.45, 78.5).
  4. The converted value updates instantly.
  5. Use the swap button (⇅) to reverse the conversion direction.

Formula & Methodology

All three scales are related through simple linear conversion:

| Conversion | Formula |
|---|---|
| Percentage → GPA (4.0) | GPA = Percentage × 0.04 |
| GPA (4.0) → Percentage | Percentage = GPA × 25 |
| CGPA (10.0) → GPA (4.0) | GPA = CGPA × 0.4 |
| GPA (4.0) → CGPA (10.0) | CGPA = GPA ÷ 0.4 |
| Percentage → CGPA (10.0) | CGPA = Percentage ÷ 10 |
| CGPA (10.0) → Percentage | Percentage = CGPA × 10 |

The base unit is GPA (4.0). All conversions go through this base internally.

Reference table:

| Percentage | CGPA (10.0) | GPA (4.0) | Grade |
|---|---|---|---|
| 90–100% | 9.0–10.0 | 3.6–4.0 | Outstanding |
| 80–89% | 8.0–8.9 | 3.2–3.56 | Excellent |
| 75–79% | 7.5–7.9 | 3.0–3.16 | First Class |
| 60–74% | 6.0–7.4 | 2.4–2.96 | Second Class |
| 50–59% | 5.0–5.9 | 2.0–2.36 | Pass |

Note: These conversions are standard linear approximations. Different universities and institutions may apply their own grading tables that deviate from these values. Always refer to your institution's official conversion policy for formal academic submissions.

Frequently Asked Questions

A GPA scale converter converts a grade point average between different grading systems: the US 4.0 GPA scale, the Indian 10-point CGPA scale, and percentage marks. It lets students and employers compare academic performance across different educational systems and grading conventions.
The standard approximation is: GPA (4.0) = Percentage × 0.04. So 75% equals approximately 3.0 GPA, 85% equals 3.4 GPA, and 95% equals 3.8 GPA. This is a linear approximation used by many universities for transcript conversion and is not universal — some institutions use their own conversion tables.
CGPA (10-point) multiplied by 0.4 gives the equivalent GPA on a 4.0 scale. A CGPA of 8.0 converts to 3.2 GPA, a CGPA of 9.0 converts to 3.6 GPA, and a 10.0 CGPA converts to 4.0 GPA. Equivalently, multiply CGPA by 10 to get the approximate percentage.
No. The 4.0 = 100% / 0.04 conversion is a widely used approximation but is not mandated by any single authority. Individual universities, graduate schools, and employers may use different conversion tables. Always check the specific institution's stated conversion policy when applying for admissions or jobs.
GPA (Grade Point Average) typically refers to the grade average for a single semester or academic term. CGPA (Cumulative Grade Point Average) is the average across all semesters of a programme. In the US, GPA commonly uses a 4.0 scale; in India, CGPA commonly uses a 10.0 scale, though some institutions also use 4.0 or 10.0 interchangeably.
A CGPA of 8.0 out of 10.0 is generally considered good at most Indian universities and corresponds to approximately 80% and a 3.2 GPA on the US 4.0 scale. Many top Indian companies and graduate school programmes set a minimum CGPA threshold of 7.0–8.0. A CGPA above 9.0 is considered distinction-level at most universities.
Requirements vary significantly by programme and university. Many US graduate programmes set a minimum GPA of 3.0 (out of 4.0), equivalent to approximately 75% or a CGPA of 7.5. Competitive programmes at top universities typically expect 3.5 or above. Always check the specific programme's stated requirements.
Multiply your CGPA (on a 10.0 scale) by 10 to get the approximate percentage. A CGPA of 7.8 equals approximately 78%. Many Indian employers and government recruitment notices specify minimum percentage requirements, making this conversion necessary for candidates from universities that award CGPA.
The converter handles the three most common academic grading formats in India and the US: 4.0 GPA, 10.0 CGPA, and percentage. Other scales such as the 5.0 GPA scale used at some US universities, the 7-point scale used at some Australian universities, or letter-grade systems require separate conversion tables not included here.
The formula CGPA = Percentage / 10 is a standard approximation used by many Indian universities including those affiliated with CBSE and several state boards. However, some universities such as Anna University or VTU use their own grading tables that do not follow a simple linear relationship. Check your university's official grading policy for the precise conversion.
First class with distinction is typically awarded for scores above 75% or CGPA above 7.5 at most Indian universities, though the threshold varies. This corresponds to approximately a 3.0 GPA on the 4.0 scale. Some institutions reserve distinction for scores above 80% or 8.0 CGPA, which corresponds to 3.2 GPA.
