Rensselaer Polytechnic Institute GPA Calculator & Percentage Converter

Q: What GPA scale does Rensselaer Polytechnic Institute use?

RPI uses a plus/minus 4.0 quality-point scale. A = 4.00, A- = 3.67, B+ = 3.33, B = 3.00, B- = 2.67, C+ = 2.33, C = 2.00, C- = 1.67, D+ = 1.33, D = 1.00, and F = 0.00. RPI does not award an A+, so the maximum GPA is 4.00.

Q: Does RPI have an A+ grade?

No. RPI's grading scale tops out at A = 4.00. There is no A+ grade, so a 4.00 is the highest possible GPA at RPI.

Q: What is the difference between quality points and quality hours?

Quality points are the quality-point value of a grade multiplied by the course's credit hours. Quality hours are the total graded credit hours that count toward your GPA. Your GPA is total quality points divided by total quality hours.

Q: How do I convert my RPI GPA to a percentage?

The standard conversion is Percentage = GPA × 25, which equals (GPA ÷ 4.0) × 100. For example, a GPA of 3.5 converts to 87.5%.

Q: Which grades are excluded from my RPI GPA?

Grades of W (Withdrawn), AU (Audit), P (Pass/No Credit), S (Satisfactory), IP (In Progress), and Z carry no quality points and do not contribute to quality hours, so they do not affect your GPA. I (Incomplete) and F (Fail) count 0 quality points in quality hours.

The Math

How RPI GPA Is Calculated

RPI multiplies each quality point by credit hours to get total quality points, then divides by total quality hours.

RPI GPA Formula

\[ \text{GPA} = \frac{\displaystyle\sum \text{Quality Points}}{\displaystyle\sum \text{Quality Hours}} = \frac{\displaystyle\sum (\text{Quality Point} \times \text{Credit Hours})}{\displaystyle\sum \text{Credit Hours}} \]

Quality PointsQuality-point value × credit hours for each course

Quality HoursTotal graded credit hours (excludes W, AU, P, S, IP, Z)

📝 Worked Example

An example using three courses:

Course	Credit Hours	Grade	Quality Point	Quality Points
MATH 1010	4.0	A	4.00	4 × 4.00 = 16.00
PHYS 1100	4.0	B−	2.67	4 × 2.67 = 10.68
CHEM 1100	4.0	C+	2.33	4 × 2.33 = 9.32
Total	12.0	—	—	36.00

Plugging into the formula:

\[ \text{GPA} = \frac{36.00}{12.0} \approx \mathbf{3.00} \]

The Conversion Formula

RPI 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%.

Letter Grade	Quality Point	Definition
A	4.00	Excellent
A−	3.67	Excellent
B+	3.33	Good
B	3.00	Good
B−	2.67	Good
C+	2.33	Average
C	2.00	Average
C−	1.67	Average
D+	1.33	Passed (not for graduate students)

📌 Grades Excluded from GPA

The following marks carry no quality points and are not counted in quality hours: W (Withdrawn), AU (Audit), P (Passed/No Credit), S (Satisfactory), IP (In Progress), and Z (Grade Unknown).

Grades I (Incomplete) and F count as 0 quality points within quality hours and therefore lower your GPA until resolved.
