Why convert a percentage to GPA?
Many schools and exam boards report results as percentages, while universities and employers, especially in the United States, often ask for a GPA on the 4.0 scale. If you are applying abroad, transferring between institutions or filling in a scholarship form, you may need to express your marks both ways.
There is no single worldwide conversion. This calculator offers the two most widely used approaches: the standard letter table used by most US high schools and colleges, and a linear conversion that scales 0–100% directly onto 0–4.0. Always check whether the institution you are applying to publishes its own table.
How to use it
- Enter your percentage, for example an overall average or a single course score.
- Choose the conversion method: the standard letter table, or the linear formula.
- Read your GPA and letter grade. The matching row in the table below is highlighted.
How the conversion works
Standard table: your percentage is placed in a letter band (for example 83–86% is a B), and the band's grade points are your GPA (B = 3.0). Results jump in steps: 86% and 83% both give 3.0.
Linear: the percentage is scaled straight onto the 4.0 range.
GPA = Percentage ÷ 25 (equivalently, Percentage ÷ 100 × 4)
The linear method gives a smoother result but is generally lower than the table for good scores. An 85% average is 3.0 on the table but 3.4 with the linear formula.
Examples
- 95% is an A, a 4.0 GPA on the standard table, and 3.8 with the linear formula.
- 85% is a B, 3.0 on the table, and 3.4 linearly.
- 72% is a C−, 1.7 on the table, and 2.88 linearly.
More worked examples
Two scores: 88% is a B+ (3.3) on the standard table, or 3.52 with the linear formula. 76% is a C (2.0), or 3.04 linearly.
Common mistakes to avoid
- Assuming one worldwide scale. Universities in different countries use different cut-offs; check the institution's own table.
- Converting your overall average only. Most universities convert course by course and then average, so use the GPA calculator for accuracy.
- Mixing the two methods. Pick one method and use it for every course.
