*Weighted GPA can exceed 4.0How the US 4.0 GPA Conversion Works
The US 4.0 GPA scale is a standard used across American educational institutions. Converting international or non-standard grades is crucial for admissions. This tool employs established equivalency tables to ensure an accurate and fair representation of your academic performance.
Calculation Formula and Weighting System
The unweighted GPA is calculated using the following general formula: $$Unweighted GPA = \frac{\sum (Course GPA \times Credit\:Hours)}{\sum Credit\:Hours}$$
This calculator includes a **Course Weighting System** (AP/IB/Honors) which adds an additional bonus to the US 4.0 score before the final calculation. An AP/IB course typically adds **1.0 point** and an Honors course adds **0.5 points** to the standard 4.0 scale conversion for that course, resulting in a *Weighted GPA* that can exceed 4.0 (up to 5.0).
Importance of Accurate GPA Calculations
An accurate, standardized GPA provides a uniform measure for admissions officers to compare applicants from diverse educational backgrounds. It’s an essential part of your college application, signaling your academic readiness and commitment to rigorous coursework. Ensure you use the correct credit hours and identify your AP/IB/Honors classes properly.

Frequently Asked Questions (FAQ)
Q1: How does this calculator handle letter grades like A+ or B-?
A1: Letter grades are mapped to their standard 4.0 unweighted equivalents. For example, A+ and A both typically map to 4.0, A- maps to 3.7, B+ maps to 3.3, and so on. The tool automatically detects the letter format and applies these standard conversions.
Q2: What is the difference between Weighted and Unweighted GPA?
A2: The Unweighted GPA provides a score out of a perfect 4.0 and doesn't account for course difficulty. The Weighted GPA (often up to 5.0) adds bonus points (typically +0.5 for Honors and +1.0 for AP/IB courses) to reward students for taking more challenging classes.
Q3: Can I use this for university or college grades?
A3: This tool is specifically designed for high school marks. University or college GPA conversions often involve different scales (like the US 4.0, 4.3, or 5.0 systems) and may require a different methodology.
Q4: How are fractional credit hours (e.g., 0.5) handled?
A4: The calculator correctly accounts for fractional credit hours. The converted GPA value for the course is multiplied by the credit hour weight before being summed up with other courses to calculate the final cumulative GPA, ensuring accuracy for semester-long or quarter-long courses.
Q5: What are the US 4.0 GPA classifications (A, B, C)?
A5: On the 4.0 scale, a 4.0 is an 'A' grade (excellent), 3.0 is a 'B' (good), 2.0 is a 'C' (average), and 1.0 is a 'D' (poor but passing). Your final GPA classification will be displayed in the results summary.
