The Math

How OU GPA Is Calculated

OU multiplies each grade point by credit hours to get quality points, then divides total quality points by total graded credit hours.

OU GPA Formula
\[ \text{GPA} = \frac{\displaystyle\sum \text{Quality Points}}{\displaystyle\sum \text{Graded Hours}} = \frac{\displaystyle\sum (\text{Grade Point} \times \text{Credit Hours})}{\displaystyle\sum \text{Credit Hours}} \]
Quality PointsGrade point value × credit hours for each course
Graded HoursTotal graded credit hours (excludes P, S, W, I, etc.)

📝 Worked Example

Three courses on the OU 4.0 scale:

CourseCredit HoursGradeGrade PointQuality Points
ENGL 11133.0A4.003 × 4.00 = 12.00
MATH 19144.0B3.004 × 3.00 = 12.00
HIST 14833.0C2.003 × 2.00 = 6.00
Total10.0——30.00

Plugging into the formula:

\[ \text{GPA} = \frac{30.00}{10.0} = \mathbf{3.00} \]
Tool 2

OU GPA to Percentage Converter

Convert your 4.0-scale OU GPA to an equivalent percentage instantly.

Convert GPA → Percentage

Enter any OU GPA between 0.0 and 4.0.

The Conversion Formula

OU uses a 4.0 scale, so:

\[ \text{Percentage} = \text{GPA} \times 25 \quad \text{or equivalently} \quad \text{Percentage} = \left(\frac{\text{GPA}}{4.0}\right) \times 100 \]

Example: If your GPA is 3.5, then Percentage = 3.5 × 25 = 87.50%.
