GPA Converter
Whether you’re applying to a US university, seeking a scholarship, or comparing your academic standing internationally, you need to translate your grades into a common scale. A GPA converter takes your existing grades–be they percentages, letter grades, or a 5.0-scale GPA–and produces the equivalent on a 4.0 scale (the most widely used in the United States) or onto other systems.
The free online GPA converter on this page handles all standard conversions instantly. Just choose your grading system, provide your grades, and see the result – a 4.0, percentage, or letter grade equivalent.
The calculator supports unweighted 4.0, weighted 5.0 (AP/IB), percentage, and letter grade scales. Once you get your result, the information below explains the methodology behind each conversion.
What Is a GPA and Why Convert It?
GPA (Grade Point Average) is a numerical summary of your academic performance, usually calculated on a 0–4.0 or 0–5.0 scale. In the US, colleges use the GPA to compare applicants from different school systems. If your high school or university uses a different grading system–say, a 10-point CGPA in India or percentage marks in the UK–you need to convert it to a US-style 4.0 GPA for applications. Even within the US, weighted GPAs (including honors or AP courses) often must be reduced to an unweighted 4.0 equivalent. A GPA converter simplifies this process, reducing the risk of manual calculation errors.
Common GPA Scales: 4.0, 5.0, Percentage, and Letter Grades
Understanding the scales is the first step in any conversion. The table below shows the standard mapping of letter grades to percentage and 4.0 values (unweighted).
| Letter Grade | Typical Percentage Range | 4.0 Scale |
|---|---|---|
| A+ | 97–100 | 4.0 |
| A | 93–96 | 4.0 |
| A- | 90–92 | 3.7 |
| B+ | 87–89 | 3.3 |
| B | 83–86 | 3.0 |
| B- | 80–82 | 2.7 |
| C+ | 77–79 | 2.3 |
| C | 73–76 | 2.0 |
| C- | 70–72 | 1.7 |
| D+ | 67–69 | 1.3 |
| D | 63–66 | 1.0 |
| D- | 60–62 | 0.7 |
| F | Below 60 | 0.0 |
Note: Some schools may shift these ranges slightly (e.g., A– may be 90–93). Always check your institution’s policy.
- 4.0 Scale (Unweighted): The standard US system where each course’s letter grade is assigned a point value (A=4.0, B=3.0, etc.), and the GPA is the credit‑weighted average.
- 5.0 Scale (Weighted): Used when advanced courses (AP, IB, Honors) are given an extra 1.0 point. For example, an A in an AP class might be worth 5.0. To convert a 5.0 scale GPA to a 4.0 scale, you typically subtract the 1.0 bonus from each weighted grade and recalculate.
- Percentage Grades: Common in many countries and some US schools. A percentage directly reflects test scores (e.g., 85%). There is no universal formula to convert percentage to a 4.0 GPA; the table above provides a typical mapping.
- Letter Grades: The simplest input; each letter maps to a point value on the chosen scale.
How to Convert Your GPA to a 4.0 Scale
You can convert manually using the table above. For a single course: if you have a B+ (87–89%), that’s a 3.3 on a 4.0 scale. To calculate a cumulative GPA from multiple courses, multiply each course’s points by its credit hours, sum those products, and divide by total credits. The converter on this page does the arithmetic automatically.
If your school uses a weighted 5.0 scale, the key is to recalculate each course without the added weight. For example, an A in an honors course that originally counted as 5.0 becomes 4.0. After stripping the weights, average the new 4.0‑scale points by credits. The GPA converter includes a setting that lets you switch between weighted and unweighted inputs for an instantaneous result.
International Grade Conversion: CGPA, Percentage, and More
International transcripts often use a completely different numeric scale.
Indian 10-point CGPA to 4.0 GPA
Many Indian universities issue a Cumulative Grade Point Average on a 10-point scale. The widely accepted quick conversion is:
GPA on 4.0 scale = CGPA × 0.4
Example: CGPA 8.5 → 8.5 × 0.4 = 3.4
A more precise method uses a look‑up table, but the multiplier is sufficient for most estimates. Input your CGPA into the converter above for an instant result.
Percentage (e.g., UK, India) to 4.0 GPA
There is no single standard. A common rule of thumb is divide by 25 (85% → 3.4), but this may understate the value at the top or bottom of the scale. Credential evaluation agencies such as WES use detailed conversion tables. For any official application, you should obtain a professional evaluation. The converter uses the most common, publicly available mapping to give a realistic estimate.
UK Honours Degree Classifications
British degrees are often described as First-Class Honours (70%+), Upper Second (2:1, 60–69%), etc. There is no direct 1:1 mapping to a US GPA, but broad equivalences exist: First ≈ 4.0, 2:1 ≈ 3.3–3.7, 2:2 ≈ 2.7–3.0. The GPA converter can approximate a percentage score into a 4.0 equivalent if your university provides a numeric mark.
