Grade Converter
Percentage (%) to US Letter Grade
Understanding Grade Conversion
Turning a raw percentage (0-100) into a standardized Letter Grade or GPA is crucial for college admissions. This tool simplifies the complex grading scale used in the US and international universities.
US GPA Standard
Our algorithm follows the strict 4.0 grading scale accepted by Ivy League colleges and Common App. (e.g., 93% = 4.0).
Instant Result
Don't waste time on manual charts. Type your marks from any exam (100 or 500 total) and get the normalized Letter Grade instantly.
Visual Indicator
Results are color-coded. Seeing an A in Green or a C in Yellow helps you instantly gauge your academic standing.
How is Percentage Converted to GPA?
While every university has minor variations, the standard mathematical formula logic is:
- A Grade (Excellent): Percentage between 90% to 100%. (GPA: 3.7 - 4.0)
- B Grade (Good): Percentage between 80% to 89%. (GPA: 2.7 - 3.3)
- C Grade (Average): Percentage between 70% to 79%. (GPA: 1.7 - 2.3)
- D Grade (Passing): Percentage between 60% to 69%. (GPA: 1.0)
Note: Any score below 60% is generally considered an 'F' (Fail) or 0.0 in the US academic system.

| 77 - 79 | C+ | 2.3 | Average + |
| 70 - 76 | C | 2.0 | Average |

Common Grading Questions
What is an 'A' grade in percentage?
Typically, any score above 90% or 93% is an 'A' grade depending on whether the school uses +/- grading. An 'A' signifies superior performance and adds 4.0 points to your GPA.
How do I convert marks out of 500 to a Letter Grade?
First, convert marks to percentage: (Scored / 500) × 100. For example, 400/500 = 80%. Enter 80% into this tool to get the Letter Grade 'B-'.
Is 75% a bad grade in College?
No, 75% converts to a C grade or roughly a 2.0 GPA. While not an Honor Roll score, it is a passing grade accepted by most undergraduate programs for degree completion.
Grading Systems Explained
Expert answers to the most common queries about Grade Scales, GPA calculation, and international equivalencies.
What is considered a "Passing Grade" globally?
In the US Academic system, a 'D' Grade (60-69%) is widely considered the lowest passing score for undergraduates, although many courses require a 'C' (70%+) to progress to the next level. In contrast, the UK Grading System considers 40% as a pass for a Bachelor's degree. Always check your university's specific handbook as standards vary by region.
Does 90% always equal a 4.0 GPA?
Not always. While most schools use the standard 4.0 scale where 93-100% is an 'A' (4.0), some institutions use a weighted system (5.0 scale) for Honors or AP classes. For standard college admissions, authorities like The College Board often convert a raw 93%+ directly to 4.0, representing "Excellence" or Superior Performance.
How accurate is this tool for Indian Students?
This calculator acts as an excellent predictor for students converting percentages to the US system. For example, if you score 85% in CBSE/ICSE, it translates to a 'B' or '3.0 GPA', which helps you gauge your eligibility for Universities in the USA or Canada before official transcript evaluation.
Difference between Unweighted and Weighted GPA?
This Percentage to Letter Grade Calculator provides an "Unweighted GPA" based strictly on numerical scores. Weighted GPAs (often going up to 5.0) account for course difficulty (like AP/IB). If your transcript uses difficulty multipliers, your final GPA might be higher than what is shown here.
