Worcester Polytechnic Institute GPA Calculator & Percentage Converter

Q: What GPA scale does Worcester Polytechnic Institute use?

WPI uses a traditional 4.0 grade-point scale: A = 4.00, B = 3.00, C = 2.00, D = 1.00, and F = 0.00. WPI does not use plus or minus grades, so there is no A+, A-, or B+.

Q: Does WPI maintain a cumulative GPA?

WPI does not print a cumulative GPA on undergraduate transcripts. Students who need one for graduate or professional school applications may request a numerical equivalent from the Registrar, calculated as A = 4.0, B = 3.0, C = 2.0.

Q: Is there an A+ at WPI?

No. WPI uses only the letter grades A, B, C, D, and F with no plus or minus modifiers. The highest grade point is A = 4.00.

Q: How do I convert my WPI 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 left out of my WPI GPA?

Marks of AU, NC, P, I, W, SP, and UP carry no grade points and are excluded from both grade points earned and credit hours, so they do not affect your GPA.

The Math

How WPI GPA Is Calculated

WPI multiplies each grade point by credit hours to get grade points earned, then divides the total by the total credit hours.

WPI GPA Formula

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

Grade PointsGrade point value × credit hours for each course

Credit HoursTotal graded credit hours (excludes P, NC, AU, W, I, etc.)

📝 Worked Example

A sample calculation using three courses:

Course	Credit Hours	Grade	Grade Point	Grade Points Earned
MA 1021	3.0	A	4.00	3 × 4.00 = 12.00
PH 1110	3.0	B	3.00	3 × 3.00 = 9.00
EN 1219	3.0	C	2.00	3 × 2.00 = 6.00
Total	9.0	—	—	27.00

Plugging into the formula:

\[ \text{GPA} = \frac{27.00}{9.0} = \mathbf{3.00} \]

The Conversion Formula

WPI 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%.

📘 WPI Grade Points (4.0 Scale)

Note: WPI uses no plus or minus grades — there is no A+, A−, or B+.

Letter Grade	Grade Point	Definition
A	4.00	Excellent
B	3.00	Good
C	2.00	Acceptable
D	1.00	Passing (consortium / graduate / non-degree)
F	0.00	Failure

📌 Grades Excluded from GPA

The following marks carry no grade points and are not counted in credit hours: AU (Audit), NC (No Credit), P (Pass), I (Incomplete), W (Withdrawal), SP (Satisfactory Progress), and UP.

WPI undergraduates normally receive A, B, C or NR (No Record). The D and F grades apply to consortium, non-degree, and graduate students. The numerical equivalent uses A = 4.0, B = 3.0, C = 2.0.
